What is the best way to seal galvanized metal and black pipe for air lines.
There will be a regulator in the line also, and i am not sure what that is
made of. Some people say teflon tape and some say some type of pipe dope. Is
it ok to use both? Is it necessary to tighten the parts as much as possible
and still get the angle needed for the next piece? If pipe dope is a good
idea, what is the best kind for air line, 135 psi.
Thanks for the help...

I used teflon tape on all my pipe joints. I run about 35 ft for my air
lines.

Loctite thread sealant #30534. Amazing stuff.

As I run airlines that will be connected to CNC equipment with very
expensive and delicate air solenoids..I use a teflon or PTF based pipe
dope and NO tape. This after getting a number of service calls
because an air function quit working and finding the solenoid plugged
with a piece of teflon tape.

YMMV of course.

I'll second the Loctite Thread sealer. It is very good for pipe joints.
I've used their hydraulic thread sealer many years ago (not sure if it's
still around) and their "just plain thread sealer" lately and like them much
better than Teflon tape. The possible problem with Teflon tape in pneumatic
and hydraulic applications is that small fragments of the tape can migrate
into the pipe and potentially clog small passages and orifices. Just my
$.02 worth.

I wouldn't use it on the same joint, no.

Is it necessary to tighten the parts as much as possible
and still get the angle needed for the next piece? If pipe dope is a good

Is your pipe rated for that pressure?

Generally, I go by the "tighten until it's snug and then tighten further
until it lines up". It's a tapered thread so it works well that way. I
prefer the brush-on pipe glop with teflon but not for any reason other
than that's what I use. Teflon tape is a pain in the ass, especially if
you have to redo a joint.

Does this product have Teflon in it? It seems the pipe dope with tefloin is
good also. thanks for the reply

I saw a product today called Rector Seal T plus 2 pipe dope. It had tefl;on
built into it. From thje resluts from this post teflon is a good thing. I
have talked to quite a few people and some say tape, some say pipe dope, so
i may try pipe dope with teflon. Hopefully that will do the job first
time...thanks to everyone

I ran black iron pipe for a new natural gas installation. Following
the directions from the store I used teflon tape. All joints were
tightened properly. All joints leaked. Every last one of them. I then
called the gas company and they said that teflon tape is not to be
used with black pipe because of the usually poor thread quality. Using
pipe dope with teflon sealed all joints. And the next time I ran black
pipe for gas I had the same results. The teflon pipe dope worked
perfectly.

Thanks for that info. I was also going to ask what gave more room for error.
When i say that i mean moving the fitting slightly to get lined up. Thanks

Pipe dope with Teflon is great. also tighten the heck out of it, then turn
it 'till the fittings go the way you want. Most of the time when I find
leaks it is because the joint is loose. Rarely I run across a bad fitting.
Greg

I have never used the pipe dope. Do i just put it all the way around the
entire threads? Do i put it on the male and female portion of the threads?
Would extra dope around the fitting and pipe after it is assembled help with
sealing? Sorry for all the questions, but I only want to do this once.
thanks

Just apply it to the pipe, male threads, not the fitting, all the way around
the threads, then screw it togather. No, do not apply any more afterward, it
does no good. As far as I am concerned, 90% of the job of pipe dope is to
lubricate the threads during assembly. If the pipe is assembled properly it
will not need sealant. In fact I have assembled pipe with nothing more than
grease when nothing else was handy. The crest of the thread will compress
into the root of the thread and seal well by itself, as long as you can
screw it togather, hence the lubrication side of pipe dope.
Greg

Keep in mind I had to have one of the pipes cut and threaded at Home Depot
and I am not sure the guy knew exactly how to operate the machine. The
threads had some significant burrs that I took off with a wire brush on a
grinding wheel motor. I hope that will do the trick. Thanks for the help...

The problem with that is the strong possibility of removing far too
much material with the brush, unless you just lightly touched it to
the wheel to take off the gross parts. If you buffed it thoroughly,
yer SOL, pard. DAMHIKT sigh

I bought a small tube of pipe dope last time. Then I saw the pipe dope
with teflon for a buck more. I'll buy that when this small tube runs
out. You'll want to use plenty on the male threads when you assemble
your pipes, Tom.

The Oatey teflon-bearing paste (in the white tube with the red and black
label) is rated for high-pressure hydraulic systems as well as plumbing.
The stuff is almost "miracle goo" for those nasty little drips that all
permanent hydraulic machines seem to develop. (Coffee cans work well for
fixed-placement equipment, too! G)

I had to build some iron pipes with teflon tape only, so I managed to
figure out a trick. Wrap the tape around the pipe clockwise, starting
at the base of the threads. Work your way out to the end, then lay down
three full wraps near the tip. Makes it fiddly to align, but the extra
tape gets ripped apart and smeared through the joint and does a good job
of protecting the remainder of the tape.
I had about forty-ish joints, none of which leaked. But, only about
40 psi water.
But I'd have used dope if it were available.

says PTFE on the can. I guess that means teflon, dunno for sure. But it
seals air lines better than anything else.

The machinery we produced occasionally showed the same problems.
Switching to Teflon pipe dope eliminated the problem. However, when
the assemblers got in a hurry, the joints with too much dope didn't
look very pretty. Still better than tape in the system under the same
circumstances I guess.

Teflon dope ..tape may be fine for some stuff but dope/paste is still
hard to beat for 99% of everything.
