Be aware. if you overpressure it the schrader valve could explode out of the can like a bullet, especially if you accidentally drop it and the can lands "just wrong". the can itself has been weakened buy introducing a hole into its structure. Hacks like this can be very dangerous. much safer to just buy a pressure pot for your compressor or a pump pack designed for the purpose.

By using a punch, you create more surface (mate-ing) area between the Brass Tire Valve & The Can. Great idea. Can should last a life time. Also by positioning the Brass Tire Valve @ the top of the can, (above the liquid level) you keep the solvent from continuous soaking of the Schrader Valve gasket / seal. Yes you can drill, but I would argue the punching of the hole will give a more desired mechanical result. Thanks for sharing. Also, on your punch, after you achieve the correct diameter hole to receive the Brass Tire Valve, you could mark with a pen of some type, or scratch a line on the tip of the punch.

[@BTW...]

The dispensing valve in the can has a low service life, intended for single use and so, built cheap. It is not serviceable. The can will not "last a lifetime" unless you mean a few refills. Placing the charge valve in the base pressure dome is a stupid idea, but not for the fluid immersion issue, which the valve will always suffer, be it vapor of fluid in a pressure charged can. Drilling into the can is a messy stupid idea. Pearce the small hole and open up by roll forming using a hardened steel rod (screwdriver shaft) is far superior. The hole only needs to be 1/4" diameter if you buy the cheap copper hose tail Schrader fittings. (HVAC industry) Certainly not agricultural tyre stems.

That’s an awesome idea. People don’t realize many times that chemicals that many people believe to be next to free or cost very little in repIair/manufacturing commercial/industrial settings are actually pretty expensive especially in small use applications scenarios ie. Aerosol sprays vs refillable compressed air sprayers. I worked for a chemical company and most sales were industrial totes of product but some of the same products in spray cans were 3-4 times the price or more and would still not equate the quantity of product difference. For those wondering and are not aware , there are already refillable compressed air bottles sprayers but last I was involved w that industry, they were expensive as in $100 plus USD for a slightly larger sized can than the one this gentleman modified.

If you get some AC system valves you also get valve cores that are PTFE, which makes them resistant to much more chemicals as well. Plus no turning involved, just get those without a tail, as then all you have to make is the roughly 3/8 hole to put them in. Or put the cores in the regular valve, as they do fit, making it chemical resistant, say you want to have a spray bottle of acetone or MEK , which dissolves regular neoprene rubber very fast.

​@@rchighfield1 - Yes, BUT... You will leave residue from your refill in your A/C service hoses. Not ideal, IMHO.

Still, if you have A/C gauges and hoses, you can re-pressurize the spray cans with NON-OXYGEN gas (you know which kind!), and eliminate the explosion hazard you get with compressed air. But NEVER pressurize cans with straight Oxygen!

[@emptech]

That's a lot of effort to go through to extend the life of a spray can. My issue is I have cans of wd-40 and other substances where the propellant is gone. Sometimes I can take a blog gun, connected to a compressed air source and using the nozzle to pressurize the can. I remove the little plastic nozzle, press the rubber tip against the little hol3 in the can and press the button. Most of the time I can hear the air bubbling inside the can. If this works, for you, it will allow you to use the last bit in the can. The problem is, doesn't always work. I think a nozzle has to be machined that acts like the plastic spray nozzle. I could machine one, just have better things to do. You can actually purchase containers that are made to be pressurized and refilled, can't remember the brands. The last time I used one, the can leaked a bit. Should say this, but I've taken 30 pound refrigerant jugs, have silver soldered 1/4" male flare fittings with schraeder valves, that allows one to fill the tank with compressed air. I think the "illegal" part is transporting the container on public roads, since the ruling seems to come from the DOT. Keep up the good work. Jim

[@jimthvac100]

the problem with refilling those refrigerant jugs is the metal is so thin and it will rust on the inside and can explode and kill you. When they have refrigerant inside they cant rust but will with air inside.

Hallo, This is In German. Das ist eine tolle Idee. Habe mir jetzt nicht alle Kommentare durchgelesen, vielleicht wurde das eine oder andere schon mitgeteilt. Meine Erfahrung dazu ist. Die Lebensdauer des Sprühkopfes wird auf lange Sicht nicht halten. Ein Wöchentlicher Betrieb im Jahr ergibt eine Lebensdauer von einem halben (1/2) Jahr. Privat habe ich Zwei die jetzt mindestens ca. 8 Jahre halten. Die werden jetzt am Sprühkopf undicht. Und das wiederbefüllen dauert mir persönlich recht lange da ich Bremsenreiniger verwende und den zweiten das gleiche wie WD40 bzw Caramba benutze. Ich habe das gleiche auch mit Plastikflaschen verwendet nur die dickwandige Variante wie zb. Sinalco (0,5 L) Flaschen. Dementsprechend habe ich von leeren Dosen die Sprühköpfe auseinander geschnitten und in die Plastik Verschraubung (Verschluss) der Flasche mit JB Weld eingeklebt. JB Weld ist ein geiles Zeug. Dazu gibt es auch Videos auf ,YT. Nun kommen wir zur Sicherheit. Bis jetzt hast du (Fast) alles richtig gemacht und hast kein Feuer (Flamme) benutzt sondern den Lötkolben. Und nun kommen wir auch zu all deinen Zuschauern die das nachmachen wollen. Ehrlich gesagt, ich würde die Unterseite bzw die Konkave Seite verwenden da dieses viel mehr Druck aushält. Falls jemand nicht richtig arbeitet. ( Bei mir sind es ca. 7 Bar Kompression fülldruck bei ca.3/4 auffüll Volumen). Und ihm durch Spannungsverzerrung an der Dose um die Ohren fliegt. Nebenbei ich habe auch vor ca. 20 Jahren wiederbefüllbare Flaschen gekauft, heute sind sie ca. das doppelte so teuer wie damals aber sie funktionieren bis heute noch gut ich habe lediglich nur die sprühköpfe erneuern müssen. Und das Auffüllen funktioniert ratzfatz. In dem Sinne wünsche ich dir alles gute. 😊

This is GOT DAMNED GENIUS!! Now, if i can figure out a way to do this with a air wick spray can for my refillable, automatic sprayer it could change the world!! Those things are so expensive and last only a week maybe a little longer.

[@andreasbentz6106]

Hi Niki! Although it seems to be a good idea, it isn't. That method does work with compressed air, which is sort of OKish on large cans, although its really tedious, because you have to bring the can up to pressure very often. On small cans like the air wick stuff, it doesnt work at all. The reason is pretty simple: spray cans normally are filled with the product you want to spray plus a liquid, that has a very low boiling point, so it is - at room temperature and under normal pressure - already a gas. Compressed to 3-5bar however, it is still a liquid. A good example for such a substance is propane gas, which is indeed used in spray cans as propellant. In the propane tank you might know perhaps from a BBQ or camping stove, it is under pressure and liquid and when you release it from the tank it evaporates and becomes gas. The benefit is, that as a liquid, it takes much less space, than as gas (comparable to water, that creates an enormous amount of steam as it boils) Now this effect is used as well to propel the product out of a spray can. When you press the cap, the pressure squeezes out the product as well as some propane gas (that is why the vapes are flammable even if the product isn't). The trick is now, that as you loose pressure, liquid propane will evaporate, until the initial pressure is re-established. In simple words: the propellant gas is practically a built-in compressor, that keeps the pressure high until all the propellant is evaporated and hopefully all of the product came out of the can. With compressed air, you have only a limited airspace over the product under pressure. When that pressure is used up, you need to refill the compressed air. That is why it works soso with larger cans. With an air wick you have perhaps 1-2 ml of air under pressure. That is probably even not enough for one single spray. Sorry for popping your dreamubble and sorry for using the metric measures. Being German I'm not used to convert to imperial. Cheers Andreas

So naturally, the armchair engineer here went down the rabbit hold of burst pressures. Because this could end up being a rally cool single shot air gun! Especially with the valve on top! I found that the cans are rated for about 140psi with a burst pressure of about 200psi, so charging to 100psi should be good! What I didn't know was the importance of the solder joint itself. 50/50 tin-lead has a relatively low burst pressure of about 150 to 200psi; while 95/5 Tin-Antimony rates between 300 and 500psi.

I worry a little about air on top of a fuel, but I suppose you could use argon if you have a bottle for a mig welder. If your valve core gets eaten up by the solvent, you could try an hvac core - fits a standard schrader but is more chemical resistant and goes to higher pressure. You can get them off the ac system on junk cars. I may try this, but fill the can with my own atf/acetone mix.

[@YodaWhat]

I also worry about using compressed air to pressurize atop fuel. I advise against it, and definitely ​NEVER pressurize cans with straight Oxygen! Nitrogen (for filling tires) is available at some service stations. CO2 also works, and for some purposes, injecting some Butane would be a good way to pressurize. Using air also runs the risk of putting water into the can, which will rust through fairly quickly if there is any free Oxygen in the can.

[@alfredomarquez9777]

My favorite DIY homemade concoction to replace the expensive liquids intended for breaking away stuck or rusted fasteners, is exactly a mix of either acetone or MEK and synthetic ATF+4, around half and half, but could vary between 60/40 to 40/60, depending on how fine or coarse are the stuck threads... Way better than "PB Blaster", "Liquiwrench", "Kroil", "Würth Rost-Off", and of course the very mediocre WD-40...

cool for some situations, but generally much simpler to just put bulk liquid in a cheap pump sprayer... or if you really want wd-40 sells their own pump sprayers which are good. Main thing is to buy liquid in at lest a gallon size for best value.

[@sicks6six]

top tip of today. . when you're filling it with compressed air do it in an inflation cage, that's what they call them in a commercial setting but a strong cardboard box with the lid closed will suffice, when they go bang the valves are like bullets ! ! let's be careful out there,

[@8546Ken]

scary

[@LazerBee]

I use a cardboard box and a clip on inflator and raise the pressure remotely at the regulator. For me the box was less about safety and more about cleanliness in case of a blow out

[@--harry_]

We used to do this back in the day with old r22/r12refrigerant tanks. They worked great to inflate tires. The cans would rust on the inside because of the moisture in the air. Then they would explode killing people. The government shutdown the reusing of the cans as a result of the injured and deaths. They made the companies incorporate features to stop them from being refilled.

[@737mechanic]

Luckily the inside of spray cans are coated to prevent rusting.

[@737mechanic]

@@Look_What_You_Did WOW, why dont you cut one open and look. Even the inside of soda cans are coated because the carbonic acid, phosphoric acid and citric acid would corrode the can without it. Thanks for the comment and helping the KZbin Algorithm.

[@lanedexter6303]

That looks like a good one!👍 I like refillable aerosol cans - when they work. Harbor Freight used to sell some, but it was hard to keep them working. Industrial quality refillables are expensive. I use trigger sprayers for some things, but they go bad, too. I like to keep a filled aerosol for my 50/50 acetone/ATF penetrant and one for WD40.

[@ryancantrell6480]

I use clear spray bottles for different lubes and penetrants. One thing Ive noticed with the clear bottles is how much certain liquids settle. WD40 is one that has a pearl jam like substance that settles on the bottom. It needs shaken before use or before pouring into another container such as the small bottle used to fill the aerosol cans. Just a tip!

[@johnecker4217]

This was a neat project, but if you don't want to use a pump sprayer you can go to any LOWE'S STORE and buy (for $8) a battery operated sprayer that screws on a gallon container and it sprays a stream of liquid about 20 feet. No manual pumping needed 😊. I bought 1 about 3 months ago and have used it for all different chemicals and I LOVE IT! PS--- IT'S SOLD OVER BY THE BUG SPRAYS.👍

I like the recycle process my only concern is someone figures they can add more air to last longer, we all know idiots are everywhere an they will blow up the can due to overpressure. Just buy the ones for this usage as I paid 5.99 for a plastic bottle with a hand pump built in and a metal one that has a 80 to 150 psi rating for 29.99 at HF and be safe

[@SenileOtaku]

That's my concern on it. One time I bought a "fillable" compressed air can (it was designed to be refillable, with a standard valve stem on the bottom). Nowhere on the can or the packaging did it give the maximum pressure rating of the can, so I never used it (seemed a highly unsafe item). Either couldn't find the company or couldn't get an answer from them, and whatever store I bought it from (maybe Staples?) would have been clueless on it too. These days I would have reported it to a safety agency or something like Consumer Reports.

[@vandalsgarage]

If you can operate a lathe safely, you're probably safe to handle a little compressed air.

[@ChrisHillASMR]

Stop trying to parent idiots karen. These people do dumb sht for stupid reasons because they just dont care.

[@Hammerback0]

Those cans are rated from the manufacturer to hold much more psi than most people's compressor can make. My compressor kicks off at 180 psi and it will not explode a brake cleaner can. Id be more concerned with knocking a hole in a can that has pressure in it (by accident)

[@csabakoltai5811]

[@kellyschlumberger1030]

A conical drill bit or bur run in reverse can deform a nice concave hole. Using a standard fitting it can be force threaded tightly into that hole (pliershelp). Screwing it in with some quick-set epoxy (surfaces gotta be CLEAN of oil), will seal it for years.

[@Mod-Ren-Man]

I'm sorry, I don't like to put thumbs down, but when you say "without drilling or torch" that you're showing how to do this without fancy tools. How do you "machine this down" without fancy tools...

[@irongoatrocky2343]

One can pretest the air pressure the way Plumbers and Steamfitters test gas pipe. Just make a fitting that has a PSI gauge on it put some soapy water in your can and inflate to pressure and let sit overnight and if it holds the same PSI and no leaks your good to go! The soapy water will tell you where the leaks if any are as well! after that drain rinse out and let the can dry out as well If the rated PSI is 100Psi on the can, I'd use 75 PSI on it for safety reasons and your not over stressing the can! you can always add some air if needed. Id use a dip straw as well to tell you the level of fluid is in the can as well!

[@RANDOMNATION907]

Solder the valve body near the bottom side of the can, about an inch from the bottom rim. I have inadvertently melted the _Spray Valve On The Can_ before, and moving the new fill valve down and away, eliminated that problem . . for me. But, yes, this definitely works, . . surprisingly well. Nice video, very easy to understand and I can clearly see how you are doing it. That's my biggest problem with making videos, I don't get good b-roll, so it's difficult for people to understand me.

you dont actually need a $6000 lathe or even a $1500 one. You can cut the valves off old bike or car/tractor tubes, whatever, and while there may not be a convenient flange to seat it in the can as long as you make the hole a neat fit and carefully position the valve no problem, I have not in NZ seen the valves for sale here, but they might be. And if you are desperate you could put a valve in your drill press and use a file to carefully machine a "step" for easier positioning.

Yes, you DO need a lathe. And a milling machine. And a TIG. My other car nut friends don't really agree. Guess who gets asked to do welding, turning, and milling regularly? If you don't have that stuff, you're a "replacer", No? (Hopefully with good diagnostic skills.)

[@ricoloco2803]

There's not much you can do with a lathe or a mill that you cannot do with a file and some determination. Is it practical for someone who is spoiled with a lathe and mill, no. If you own a wood splitter you're not going to split a seasons worth of wood with an ax, but if not, you don't have to freeze to death. To scrape a little bit of brass off with a file would probably take half the time that the rest of the project takes. Probably half the time setting up and turning down. It doesn't take a Skin-o-matic 5000 to skin a cat either, there's a bunch of ways.

Some rattle cans have a nice quality spray tip on them where you can change the pattern from vertical to sideways, so you can actually filll that with automotive paint and do the door jambs of your car and smaller areas easily and cheaply nice idea, one thing I would try to add is a gauge to measure how much pressure you are putting in the can to keep safe and consistent, I also would put that Schrader valve on the bottom of the can, mainly because if that pops off somebody can lose an eye or something else that's near and dear to them if it pops off the bottom it might hit one of your toes or something.,my bad I saw you addressed the problem but you could fashion a little safety loop that fits over the top that doesn't interfere with you spraying to keep you safe from that thing ever popping off you can even make one cutting up another can it only has to stop the initial inertia to work, that thing would fly off of there like a pellet gun I wouldn't want my face in front of it.

Fair idea for easy applications, but would t work for those times where cramped space requires you to have the can upside down and/or use a straw. Spray bottles don’t generally work upside down because the intake straw is then in an air pocket, and ice never seen a spray bottle that accepts a straw on the nozzle. …though if you know of a brand/style that does accept straws in the nozzle please let me know because I’ve got uses for a setup like that!
