How to Install CSST Fittings

Two ways to connect flexible natural gas and propane pipes.
Corrugated Stainless Steel Tubing, or CSST, is a flexible tubing used to supply natural gas and propane in buildings. Compression fittings are used to make transitions between pipes. Here’s how they work...

I think this is the most perfect no bs video I've ever seen. I wish more people would give directions this. Thank you.

[@ChrisRI1000]

Used Home Flex and here's what I learned 1. Make damn sure the cut is absolutely clean because burs will cause leaks and might rip up the fiber washer as well. 2. After the fitting is installed and you're ready to make connections always always always use the best pipe dope and Teflon plumber's tape on the male threads. I unfortunately followed the advice of purist plumbers using just pipe dope and had leaks that were so minor they were undetectable using soapy water. The best way to do this is to first apply a thin coat of dope followed by the yellow Teflon plumber's tape. Wrap the tape so you have 2 layers and in the proper direction so it doesn't bunch up. 3. Take the time to do this all as perfect as you can because it will save you mega hours chasing down leaks caused by sloppy work.

[@jl456]

Your not supposed to use pipe dope or tape you dummy!

[@camilo8cheryl]

And lastly leak test

This was very helpful. Thank you 🙏

when cutting csst beware the cut part is veeeeery sharp, like a razor ! i slipped up last week & an still healing. csst fittings seal properly when hand torqued.

Did you use the same pipe for both of those fitting styles

Just an observation, the slip joint pliers are being used backwards in the video.

[@waynenocton]

Wow, this is the only video I ever seen recommending 1/4 turn past hand tight, I see so many of these over tightened, it’s an oring, why do people crank so hard on them…

[@wendellfishing]

Solid... thanks!

[@AR12-AQUIL]

How long do those rubber rings last before they dry rot and leak? Would it help to put Tplus2 paste on there?

[@billsmith9249]

Pro-flex (sold by Menards and Lowes), uses silicone o-rings.

[@InCountry6970]

Proflex takes a few more steps but the sealing method looks better

[@mattlucca32]

How do you replace the gaskets??

Cut it off of the csst

I am wondering why the maximum torque the installer is allowed to apply is not mentioned.

Instructions on home-flex for 3/4 say 90 foot lbs or as tighten until it won't turn any farther.

[@twinkie27271]

@@danieltweddell5973 wouldn't that destroy the rubber O ring? The man clearly said one quarter turn.

[@mattbrouillard9571]

​@@twinkie27271 I believe from watching the home only has the metal ring and that is what he's referring to torque to 90 ft lbs. The kind with a rubber o-ring is a quarter-turn after hand tight.

Can I use underground?

[@portcitytransparency5730]

CSST piping is not approved for underground installs

[@mgfarrow]

Do you have a link to buy these?

[@winstonian88]

I have to run Home Flex Underground pipe (or the equivalent) to a gazebo about 70 feet from my BBQ connection. I'm planning on burying it. Should I be increasing the diameter of the piping to handle a run of that length? Advice is appreciated!

[@benram32]

Use yellow pvc cheaper and code approved. Make sure to sleave ie add pipethrough penetrations if your going to cover floor with concrete or pavers.

[@winstonian88]

@@benram32 Thanks. You mean add an extra sleeve where you’re going under concrete or pavers? Also, my BBQ line is 3/4. Should i bump it up to 1 inch to carry the gas the extra 80 feet, or just leave it at 3/4?

[@benram32]

There are charts to determine the pipe size required for btu of your BBQ and max distance. FYI you can always go bigger but never smaller.

[@yolo_burrito]

It depends on system pressure and load.

[@kylecooper8657]

Did you already do this project? If not, run a tracer wire with it also

[@dannyscorpion759]

Nice

[@chrisalister2297]

Be careful when putting the o-ring on that it doesn't get sliced as you pass over the sharp edge at the end of the pipe.

[@belayon2]

Don't forget to wear gloves. The ends of that cut stainless steel are extremely sharp!

[@fouroakfarm]

This stuff is a hell of a lot easier than black iron pipe

But a lot more things that can go wrong. Black iron pipe will last 50 years.

Can you tell me exactly what I need from proflex to get form the 3/4" csst line to 1" black pipe? I've searched for days.

[@averyalexander2303]

You can use a 1 inch to 3/4 inch reducer coupling to reduce the size of the black pipe to 3/4 inch so you can use the normal 3/4 inch CSST fittings to screw onto it. Obviously if you do this the 1 inch pipe functionally becomes a 3/4 inch pipe and won't be able to supply as much gas, but that may be okay depending on what you are using it for. Hopefully this helps

You call him out for not holding back properly, and your are correct. I can't stand it when people hold back wrong. Another peeve of mine is people like you who call pliers channellocks. There was no channellock in this video, just a plier. I believe it to be manufactured by Tekton (also an American company). Thanks Chap. Don't do it again, ever!

No matter how convenient flex tubing might be, I do not trust it. Black iron or traditional copper tubing are my choices. Flex tubing is too vulnerable to damage, and connecting the fittings looks hinky to me. Things can go wrong.

I use a combination of flex and black pipe on strategic areas.
