Putting together piping system for air.

I'm just about ready to start my Compressor piping system.

I am using 3/4" Galvanized Steel pipe with threaded ends.
Home Depot recommends that I use the pipe compound thread sealer sold in a can with an applicator.

Should i stick to using the sealer or is teflon thread tape OK?

They will both work, I used teflon tape and it is fine.

Correctly using tape is good! But some people get in a hurry or aren't great with tape and pieces of it get loose in the air system at the worlds worst times! Murphy's law.

For that application I prefer Rector-Seal , It does not ever get hard and it will seal good. Its good for natural gas and LP lines also.

I have always used the liquid pipe dope, just stay a little back from the end of the pipe and you should be all set. Both ways would work.

I like Pematex non-hardening gasket sealer, works really good and will not come off in the pipe. Just what I use but there are other sealers that I am sure are at least as good, Rector-seal is a very good one. Just remember not to over-do whatever you decide on it only takes a small amount and any excess may be squeezed out into the pipe to come back to haunt you sometime later.

I typically use a bit of both--a light smear of dope and two wraps of tape. Keep the first thread or two empty of either though so no contaminants get into the airstream.

You can use either pipe dope or tape, if you clean the threads with lacquer thinner and a little wire brush, you will have a lot less leaks.
