I'm in the process of plumbing my new compressor, I got 3/4 galvanized pipe. I'm using T Plus 2 teflon sealent on the threads I was wondering if this stuff is going to screw up my water seperator/paint hose?

It can, especally if the tape "spider webs" the opening.
As well as "strips" of it twisting into the pipe opening and comming loose.
I use Rector Seal Soft Set #5 pipe "dope" It's the standard for plumbing WaterOilGas piping of all sorts. Most plumbing supply houses carry it and probly most home supply stores.It looks like baby doodoo.

I'm not using the tape this stuff is a thick paste...so I guess I'll be alright since i'm not using the tape?

Pair, I think I would go with what Bee is recommending if you intend to paint with this setup. Teflon may not be as bad a silicone for paint but why risk it since it could cause big problems? JMO

If you put your sealant only on the male end it's next to impossible
to get any on the "inside" unless you unscrew it.
Pipe threads "push" the sealant out as you screw it together,
away from the inside.

When I had some problems getting some connections to seal airtight
I tried a lot of different sealants and the only thing that worked was
RTV silicone, I know, it sounds outrageous, but it worked and I've
not gotten any fisheyes in years.

Oh contrair jc,
It MOST likely to get liquid/paste sealer IN the pipe as IF you "overdo" the amount your slopping on the male end it will squeeze in the pipe. I know this for fact as I've pulled MANY gas pipes apart and found sealer blocking or gooped inside the pipe.
The Teflon stuff is good but just be careful about applying it to the threads.Stay away from the open end and use it sparingly.

Well I guess I should've posted this before I started but i'm finished running the pipe, hopefully I won't have any air leaks but i'm sure I'll end up taking all apart and starting over

You can use the tape or the putty, I use what ever is the handiest, sometimes you will have to redo a couple of them to get the leaks stopped, I have both types in about 110' of 3/4'' pipe and it's been in use about twenty years and no problem with the paint. If you get a leaker wire brush it and redo it, a little lacquer thinner with a wire brush is all you need to do. I have three hose reels and three dropoffs to get rid of the water and four filters, never had a problem with paste or tape. Just stay on it untill you stop all the leaks

Thanks for the reply Rob, one other question I had was where to get a short piece of rubber hose to go from compressor to hard line on the wall? get one custom made or what? thanks again

Yea, you're right.
I usually put it on pretty sparringly and keep it off the first couple of threads,
But what you said is a good point, It's easy to get sloppy with it.

[robs ss]

You will need two, any place that does hydraulic hose repair can make you up a couple, tell them how much pressure your compressor pumps up to, then they will know what you need.
I posted some stuff on the body shop forum about air lines you might want to look at, you need to keep any flat spots out of your lines for condensation problems, take a little time and study up on running air lines.
The posting is paint booth, supplied air, ventilation, air lines
