How To Bend PVC the Easy Way

[@curbyweaver4606]

Nice vid. The sand prevents the pipe from kinking and the heat relaxes the plastic. Genius.

[@jhorne18]

This surely tells you where NOT to use regular PVC pipe, one obvious place being not for the hot water side of a plumbing system or high heat areas. Very instructive video. Thanks for uploading.

[@asokan0015]

Thumbs up Gentle man. Nice, Easy, Cheap & Very useful. All the resources are within the reach of a common man like me. Thanks a ton for sharing. Keep posting.

[@jlgrizzly7972]

I used a heat gun and sand, with plywood templates to bend gray PVC conduit while wiring my shop. The sand works great to hold the shape but the price of the heat gun is worth the time savings. Thanks for a great idea I just changed up a few thing to save me some time making sweeps to run wire.

[@brianchester2122]

Never thought of using this technique to bend PVC. Have used it to bend metal pipe when a pneumatic jig was not available. A good idea. From an artistic view, a great trick for sculpting. By pushing predetermined lengths of rope into each end that is equal to the inside diameter of the PVC, making a bend in the middle of a 12 foot length of PVC is easy. The rope would hold the sand where it needs to be.Thank you for your effort.

[@tabaccopuro]

Awesome looking PVC lights. The hot sand will prevent a deformed bend but a heat gun used on the outside will assist in doing this faster. Your pvc insert is a very clever way to attach the led portion and it looks professional, but I rather do it as one piece. Overall, your video is inspirational and I will make some of these this week. Bravo!

[@brucewalter]

Great idea. Don't know why someone would dislike your video. Will keep this in mind for my next diy project that requires bent pcv.

i've used the sand in pipe for bending brass and steel tubing for years and never thought to use it for pvc with heat... great info, Thanks!!!

[@terrybush5449]

I just wanted to say thank you for your video. I watched video and chose yours. I bent a piece of 1 1/4 to about a 35 deg angle slipped it over a piece of chain link fence top rail that I had laying around, now it is a hand rail on a set of outside stairs.

[@charleswilson4598]

I am not a perfectionist so I really liked your video and thought it was a good diy idea. I used to do professional installations and we sometimes didn't have the best tool for the job and had to improvise, so a good idea was worth a lot.

[@nbm34]

Never mind the negative comments James your idea is brilliant even if someone can expand on this technique. I would find getting a spring suitable for bending, difficult. Because suitable springs are not easy to find as sand. If Indians where so good at what they do why do they leave their country for ours. and still have peasants in the fields, with thousand dying in poverty with no comment from their own people it seems. Well anyway your idea is sound practical and with no need for tools as such just a hot sand. Well done and thank you for your time in showing this to us, Respect my freind look forward to seeing more of your inventions.

[@chunlichun]

[@breeze787]

Hey your the video I've been searching for. I saw your vid once before eons ago and I was impressed on how easy it was to do with superior results. Now I have a project that requires bending pvc and I wanted to see your video before I started. Thanks for putting this up I'll probably be popping on by every once in awhile just for old times sake now.

[@michaelbujaki2462]

This is a brilliant idea. I would add a little sand to the bottom section that you don't want bent, that way you can apply heat to a lesser amount of sand.

[@shnarklevonbarkle110]

I just watched a similar video, but the guy was using a heat gun or maybe it was a hair dryer idk. He made a jig with some plywood and nails that was quite impressive. I don't recall if the curves had any severe deformation. It wasn't apparent on the video, but it was incredibly quick and easy. He was building greenhouses and using the pvc as framing. This looks cool, but is probably for those who are really meticulous about how stuff looks. It does look good.

[@alfredomarquez9777]

I was looking at how to bend a larger diameter pipe, say 1 1/4" CPVC. Reading at the comments, I found that "Technicolor Christmas" has done up to 2". To all the people that will suggest using a spring bender: there is no larger than 7/8" bending spring. I'm planning to bend 1 1/4" CPVC pipe at 30 to 45 degrees bends to clear an obstacle in a low pressure pipe used to lift water less than 30 ft.This video shows a nice method, perhaps a little slow, but his results are perfect! Congrats.

[@brinahealy942]

I'm currently using a Pipe Viper on 3/4" schedule 40 PVC pipe. DON'T EXPECT more than a 75 degree bend--as the pipe viper gets stuck. Pulling it out distorts the spring, so the spring was useless...

[@elisanch2621]

We, as electricians have been bending PVC, with heat for some time, been doing it for more than 30 years, he’s just using a different concept, that’s good, doesn’t hurt to try and improve things

[@chicagojohn5847]

Thanks for posting this video. I don't know if you invented this approach or not, but it's really very creative. I'm looking to bend some thin-wall Lexan polycarbonate tubing, and this should enable me to adjust the temperature pretty precisely relative to the glass transition temperature for this material. It's also great that the sand helps to prevent kinking. Great concept, well explained. Thanks so much!

[@olben1095]

Very creative with the lights. Makes for a modern look.

[@ElPasoTom]

Keep a hose nearby. Once bent use hose to rapidly cool inside of pipe by flushing with water also gets any remaining sand out. Thanks for video. Cool idea.

[@tommyroberts8012]

you are so smart...i love your video... thanks for spending your time to share your knowledge. You are smarted than 90% of contractors I have met and they work for me everyday....yikes.

[@keith254]

Awesome trick. Table salt on the stove should work as well. Just be careful to not over heat the pipe. Salt won't melt until over 1000 degrees F, and I think the pipe should bend around 200-300. It might be a good idea to use a temp gun on it to make sure it isn't way too hot. Salt is a good conductor and should hold heat pretty well.

[@scorp10fl53]

Goldsmiths and jewellers use sand to bend gold and silver tubing as well. Very good method although with a bit of control you could use the torch to heat the sand filled pipe itself followed by a spray bottle to cool it off rapidly. Nice adaptation of an idea!

[@romwil]

Great presentation and technique! Thanks v much for sharing with all and taking the time to create a solid informative video. I also agree that the DIY project approach with the K.I.S.S. Method is the best approach. Solid stuff.

[@jessmdevans]

very cool...pvc pipe should never be used in water over 90 degrees(they say 70) because of its low melting point. but ive seen dummies plumb their house with it because its so cheap, not knowing any better, and the pipe blowing up the size of lemons, but didnt burst. it just had these huge lemon size lumps every where, anyway that tells you that it can be deformed with very moderate temps, water heaters are generally set at 120-125 degrees. this is cool, i used to bend them with a pvc heating blanket, also they make bending springs, you can put inside the tubing, then heat the pipe with a torch, the spring keeps the tubing perfectly round cuz heating and bending pvc causes the sides to collapse and the pipe goes flat.... but this is a great method. ive never seen it, the pipe stays round and its very flexible, great going finding this out

[@gondolacrescent5]

[@terriecotham1567]

Thanks for tacking your time to make this and post very well done simple and to the point please keep up the good work

[@rafdavfl]

Good idea. But as a retired electrician, we would use the propane torch to heat the pvc and do what ever bend we needed. Being out in the field w/o electricity or a generator required the propane torch. If the bend, 90 or 45 or whatever, was buried, we didn't worry about the scorch marks left on the pvc. Out in the open, we used due care and made it look good.

[@JohnWPB]

Nice Job! Just heating the PVC and bending, as some have mentioned, would wrinkle and kink at the points of bending it. The sand serves 2 functions, to heat the plastic to make it pliable, and to keep the form of the tubing in tact.

[@intrimitidopacio1592]

we only uses old newspaper to bend a pvc... very easy.. nice presentation...

[@dannycoltra6078]

Plug both ends with corks & tape to make airtight. Air inside pipe will keep it from kinks use torch to heat pipe keeping flame far enough away to keep from burning pipe. When pipe gets limber set pipe by jig use wet cloth to cool pipe. It will be a lot quicker I am an Electrical contractor I have bent 1/2" to 6" PVC Conduit this way for more than 28 years.

[@technicolorchristmas]

Air inside doesn't prevent kinks, unfortunately.

[@pleidius]

one of the professional tools I've used is a 'glycol bender' Glycol is undiluted antifreeze. A metal tube is partially filled with glycol and heated. The PVC is inserted into the heated glycol for a few moments and when removed is very limp. Using a pair of well insulated rubber gloves you form the PVC into the desired shape and 'massage' it till it is cool enough to hold it's shape.. This process can be messy, but when you need to make a lot of bends, it is one of the fastest . . . .

[@gardensandmore1614]

+pleidius I can see how this would work, as along as heating the glycol wasn't expensive to do and not over-heated. I do wonder about the fumes.

[@pleidius]

[@paulahedge9596]

I really like your idea of pathway lighting. Have you made a step by step video on how to make them? All I can find is the one where you show how to bend the pipe. If you haven't could you? Please

[@largerooster2059]

Ever try a plastic pipe oven? It's about three feet long and comes in different sizes for pipe size. Opens up like a door hinge and you put the pipe in slowly roll it till it gets flexible then you lay on a flat surface and make your bends. No kinks or pinch. Professionals use them for all types of plastic pipe in single lines or double containment. Works perfect.

[@mrstanskaggs1]

I saw them do this in Brazil to run water pipes.. They use a bed of sand and set a fire under the bed.. the pipe is inserted int the sand for a couple of seconds and it becomes pliable: I do not remember if they put sand inside the tubes though.. It would seem to make sense to though.. They were bending a bunch at a time to run in the building they were plumbing though.. This video made me think of that instance.. Thanks! Stan

[@divusiulius7539]

First off, Thank You! You made my head explode. DIY PVC projects are taking over my life. I have just one quick question. Since I have never done this before, would a hair dryer or a Heat gun work while using the heated sand at the same time? I'm going to try both. Have you any suggestions or recommendations? I'm all ears!

[@technicolorchristmas]

I have never gotten a Hair dryer to get hot enough, a heat gun will work but it is harder to get the pipe to heat evenly along the entire length and evenly all the way around.

[@curtsiekert]

Great video. Thanks. I too would love to see the finished product. Please let me know.

[@denniskimball5578]

Awesome! Really like this simple and effective approach. Thank you!

[@romansten9]

you can also use a metal spring inside for short bends, heated by various methods. doesnt have all the same benefits of sand, but in some cases its even easier and less messy than sand.

[@epicenergy777]

Awesome video. I didn't want to strangle you by the end. Some guys voice drive you to drink after 11:46. Thank You!!

[@Blakehx]

Good idea that works well! By the way, using coarser sand that is slightly moistened will work even better! Have you tried using super hot oil, either dipping it in or filling it?

[@janetgray9685]

have you done that? I would think IIT would catch fire?

[@theone-so9br]

I've never seen it done this way before. I used to use sand inside to keep it from collapsing and heat with a heat gun to heat the pipe full of sand. A wet rag will make it cool once it's shaped. A heat gun may burn the pipe if not careful, but a hair dryer will not overheat the pipe as easily.

[@gardensandmore1614]

+Tim Chartrand True, but heating the outside of the pipe takes a while and is less efficient. If the heat is on the inside of the pipe, the pipe warms faster and less heat is wasted since the air is trying to take the heat away.

[@general5104]

Another real good and quick method of bending 1" PVC or less, is to mark it off, where the actual bend is to be and stick it up your exhaust pipe. Play with the timing, to get it just the softness you want.

[@Joani161]

Thanks, Some sort of airflow would help to cool faster. Maybe a compressor or hair dryer on cool and so on. Blowing through the pipe is best bot outside will help. Where did you find the lights?

[@lelko8]

Nice person, very polite. I bent my first PVC in 1970 . I had 4 ,4'' conduits that ran exposed for about 200' if I recall. A couple of offsets and a 90* bend. Would this method work ? You tell me . I very likely would still be there. Also there are times when schedule 80 is necessary. Again this is a very nice guy . Schedule 80 by the way is much thicker.

[@davidgreener423]

[@oobihdahboobeeboppah]

If you drag the tip of the torch backwards through the sand so that it doesn't scoop up the sand but it is riding through it backwards, you will be able to heat the sand more thoroughly heating the entire pile and help it retain the heat rather than just heating it from one side.

[@arora_for_life]

[@nickcompton8913]

I'm curious to see if this works well with bending hoses. Special bent hoses under the hood of your vehicle can get costly.

[@rkmcintire]

What not use a heating element that is flexible and can the temperature range just shy of the melt point of pvc? Seems like this take a long time to do something that should take just a few minutes. But it does show some creativity to solve a problem.

[@technicolorchristmas]

+Ronald McIntire The point of the video is to show a method that doesn't require a specialized tool. Yes, I know there are bending springs, and heat guns, and pressure benders and heating elements, and no average Jo or layman has one. This takes a bit more time, sure, but anyone can do it with rudimentary tools. It also scales up, I've done a 2" diameter pipe 10' long. No possible way to do that with any of those tools.

[@rkmcintire]

O it is a great idea. Such an ingenious method.

[@wb5rue]

+technicolor christmas Also, perhaps something other your aluminum (heat-sink) pan would work better to heat the sand.

[@timacrow]

I didn't listen to the audio so I don't know if any specific temps were mentioned, but could a larger supply of sand been more thoroughly heated in a toaster oven? One fill of sand followed by successive hot refills might speed things up. Just thinking out loud.

[@MrRobinfenn]

you would need to have some way to measure the hot sand so you don't heat up other area of the pipe another thing you can do is to use a dowel with the cork so that no sand reaches the other end. I've bent pipe using oven and open flame before I like this way I will experiment with different sizes as well

[@Cavalier_Steve]

I like you lights idea and they look really good to how do you plan on removing the black print on the side of them just out of interest. Good Job!

[@adriantp_]

Steven Watson I have found that light sandpaper does that pretty well. One should probably sand anything one intends to paint anyway. If you want to get really fancy and go for a glass finish, start with coarse and progress to fine (but that's probably not great for paint adhesion). Oh, and wear a filter mask when sanding PVC. The particles can be pretty light and float their way right into your lungs.

Forman: Why is there no pipe on the wall!?!?! We have two 1200 ft. pulls to do by lunch!!! Crewman: I was sitting here filling them with sand for 10 minutes each...little cork and everything.

[@TomBurke4015]

To make consistent copies, perhaps you could mix cement with some of your excess sand, dig a shallow hole in the ground (as a support), pour in the sand/cement mixture, press in your master tube (less than halfway covered!! :-), and let the cement harden. Then, you have a form for making perfect copies, with the bonus that the form will help cool the tubes more quickly. Probably a good idea to wiggle the master tube very slightly as the cement is setting up so that the fit isn't TOO tight, and you might also want to coat that tube with a little oil or somesuch to keep the wet cement from sticking to it. The copy tubes wouldn't need any of that.

[@gordbaker896]

So you put the master tube in concrete and let it harden. How do you then remove the 'master' bent tube? FAIL.

[@aroostookaerials7333]

+Gord Baker "Less than halfway covered," you are basically making a bent trough in the shape you need. FAIL to you sir.

[@drumzyful]

I WANNA MAKE THOSE LIGHTS I tuned in to watch the PVC bending technique which was cool but then saw those outstanding lights that you made. Can you provide a video about making those LED garden lights? I need to know everything since electrical, even though I can do basic house wiring, I'm a novice about what you quickly showed and need to know what to buy and where. I already have a couple different transformers that came with those crappy made in China lights that either lose connection easily (pressure prongs with a cam that supposedly retains force against prongs and wire) or they get knocked over by the hose or dogs... So maybe I can use them as a power source? Thanks for your time!

[@gardensandmore1614]

Hot sand is a real easy, basic way to warm PVC pipe, and there are other options that do the same thing, some of which are flexible metal tubing devices with electrical wire inside that provides the heat like Nichrome wire common to bread toasters and toaster ovens. The key is managing the heat to a temperature that won't over-heat the PVC plastic and not getting into a rush. As to keeping the heating of the same materials as cheap as possible, lots of folks use a common, small barbeque grill, get charcoal going like they were going to cook some meat and place a thicker than standard metal bowl with sand in the center after the coals get hot. Of course there is a lot of heat produced and things soon get too hot to touch without burning flesh. Again, the issue is still not getting the sand too hot, so some sort of temperature monitoring device becomes necessary. If you want to do larger diameter PVC pipe, you will likely want to make a hot-box to put pipe pieces in. A hot-box is a simple way to hold the heat in to give the PVC pipe time to soften enough to accept the desired bend, or shape. If you pre cut the pipe that will become the bent joints of a greenhouse and use plugs of wood, cork, or another substance that doesn't heat up easily, the ends of the joint pipe can be preserved in the diameter the pipe comes with from the store. What I did was install 2x4 wood pieces in the box so I could cause the pipe pieces to bend a little, heat them, let them cool, adjust the 2x4 for a bit more bend, heat the pipe, let it cool, and adjust the 2x4 again. I repeated the process until the PVC pipe pieces were bent to the desired shape. I used a small, personal barbeque grill in the bottom center of the box since I only needed the center of the pipe pieces to bend. If you don't shape the 2x4 to the diameter of the pipe, the pipe will start to show a slightly flattened section where it touched the wood formers as it relaxes, or softens while heated. An easy way to get around the problem is to shape thicker wood, as in 2x6 that has a curve matching the desired final shape of the bent pipe that also has a channel in the 2x6 that the pipe can settle into. The 2x6 will have a rounded top, sort of a shallow arc and the top of the arc does all the shaping work. The channel in the top of the arc is where the PVC pipe will settle into as it warms and softens. If you have seen mechanical metal pipe bending devices that use a simple bottle jack in a steel frame at Harbor Freight, or another store, you have seen curved pipe bending parts that push against the bottom of the metal pipe to cause a bend without flattening the pipe. Metal conduit bending devices use the same concept to bend thin wall metal pipe without causing the bend to flatten. The secret is the curved channel the round metal pipe settles into as force is applied to cause it to bend into a gentle curve. Not much to the process and the only difference is the plastic pipe rather than metal and heat to cause the plastic to remember the bend after it cools.

[@sajidahmed5079]

u cam use hot air blower gun too. Fill sand in side and close both side.Blow hot air on the spot where u want to bend and bend it.in side prevent it from shrinking .

[@awackocrank]

If you wanted to make multiple identicle pieces you could put some finish nails partly into a piece of wood that outlines the pattern, and then put the softened pieces in the pattern to cool and harden to shape.

[@technicolorchristmas]

+awackocrank I have used jigs in the past for different projects. A half round router bit into a 3/4" piece of plywood is great because you can make it almost any shape in it preserves the diameter of the pipe.

[@greedsss34]

[@ww321]

You can also do it by putting duct tape on the ends to seal the air inside. Your way is probably better for tight bends.I heat with torch on heat gun, holding it back and always moving to keep from discoloring from to much heat

[@technicolorchristmas]

+ww321 unfortunately, the sealed air method will not prevent "kinks" and the torch method often results in a scorched and discolored exterior. Even if it doesn't actually burn and bubble the surface, it often "yellows" the outside. This method, while it takes a bit more time, does neither, and that's why it's useful for some applications.

[@tonythomas951]

Ever hear the phrase "go pound sand"? Now you know where it came from. All conduit was bent by packing the conduit with sand back when conduit first came to be. It still works on metal as well as plastics but there are better ways that don't require sand such as air pressure or good bending tools.

[@jamesmonahan1819]

I found this informative. Especially the part about the PEX fitting working as an inside connector for PVC pipe. Or, was this all PEX tubing? Also.

I will keep an eye out for more of your videos.

[@tonydownunder5703]

Well done, Very good. Thanks for sharing.

[@xboa721]

Great idea. Although how's this: fill the pipe with sand first, then heat the external surface of pipe with a heat gun. The sand will help the pipe hold its shape while u bend it and overcomes heating sand (poor thermal conductor) to high temp. Cheers.

[@peterpunch1]

***** heatgun give so uneven temperature.. especially if you are trying thick pipes. I will try this method tomorrow on bigger pipes and see how it goes.. :-)

[@xboa721]

Fair call. I went out and bought a Makita heat gun - seemed like the best bang for my buck and at $100 it has digital temp control which overcomes 99% of the problems of heat guns. I can set it to a temp like say 340 degC which works nice for working with PVC.

[@acefreaky2988]

You can do similar with 110mm (4 1/2 ich ) soil pipe saves a fortune on fittings if you make sockets or slow bends out of it .

[@teefondle3000]

It would probably work well with gravel and fine sand. Thanks for the video

[@michaelledford4751]

For all the haters ,every plumber on earth should have a smelting pot & stand along with attached propane burner ,now instead of only using their smelting gear for cast iron work they can full their pot with sand that stays hot & build a simple adjustable jig for any angle with 100% accuracy, the smelting pot would hold enough sand to do 6 or 8 bends continuously .

I can see how the pipe stretch a little bit when you take out the sand and put over the inside radios of the other pipe when is still warm.Only reason it dont kink is because is just a few degrees of curve

Nice work friend. I'm interested in the LED lights. Can you provide a vendor? I'll go and search for RGB LEDs now. Peace

Have you measured the temp of the sand when poured...250 F, 300 F? , 350 F?

[@technicolorchristmas]

I have tried at lower temps (because I was impatient waiting for it to come up to temperature) and I'm sure the pipe will eventually get soft, it just takes forever. the 500-600 F seems to be a sweet spot for flexibility while maintaining integrity of the pipe and quickly cooling to set the shape.

Excellent. I just made myself a Fujara using plastic pipe, now I fancy making a curly Fujara :0) Do you think it doable to turn a 5ft pipe into a coil using this method? Cheers Gary

Is there a reason for you not to cooling it down with water while you hold it at an angel? Then you would be able to at least quadruple the ammout of bent pvc pipes. for many good reasons that i dont have.
