I just need to chase some threads in a bung in the side of my compressor tank. I manage a hardware store and we stock them up to 1". Thanks for the input.

 

[Frank The Plumber]

How bad are the threads, maybe you can clear them with a well oiled pipe ****** as a chase. In, catch, out oil , in catch out oil, a bunch of times to clear rust or debris. It can work if the threads are not too bad.

I cut 4 slots thru the threads on a ****** to act as a tap. I only ran it in a couple of times, mabey I need to do it more!!

 

[Frank The Plumber]

How does it look? Starting to see enough clean thread to seal a joint if you put some teflon tape and a bit of sealant on them. It's just compressed atmospheric air correct. Not oxygen.

 

[70Camaro]

Yes, Just air. I had just put pipe dope on it.

 

[Frank The Plumber]

As long as it's not aluminum you could use a bit of tape and a touch of dope together for a good seal.

spoolwick and teflon paste will help tremendousely on a loose thread

Would you put the tape on the male threads and the dope on the female?

I found a 2" x 11.5 NPT-It weighs 4 lbs. BAN (Bare A-- Naked)-Let me know if the other method does not work............Cranky

 

[Frank The Plumber]

Tee tape the males and apply a thin layer of dope over them. Rectorseal # 5 if available, any good dope will do. If you can run it in 4 to 6 threads and nice and tight it should work OK.

Thanks for the advice. I've been doing plumbing on the side for 20 years. I've got several friends that have rental property and they keep me busy. Toilets, faucets, vanities, waterheaters and other assorted leaks. I've always used the dope with teflon in it and on water pressure it has always worked, but this 2" plug at 140psi leaks--LOL
