Fitting Sealant (Teflon Tape vs. Loctite)

[72BlckButy]

What have you have the best luck with Teflon Tape, Loctite 545 or another thread sealant?

[72BlckButy]

I've used Teflon tape for various shop connections (air compressor line, attachments, etc.). Sometimes I have leaks sometimes I don't.

I've only used the Loctite 545 sealant a couple of times and I've had good luck with it as well.

Depends on application. I use teflon tape, thread locker, teflon paste, hi-tack, aviation, and rtv.

[72BlckButy]

Just thought it would be nice for those with leaks in their air ride systems.

Just a typical electric air ride setup.

I use liquid/paste sealant, maybe not 545 but others (permatex) make it as well. I haven't tried tape for this application though it may do just fine.

[Rochlow]

I've used Loctite 545 on a few trucks and it has worked great for me. However, it's expensive.

[Sammy]

For the air fittings loctite. But agree the price is insane.

I used loctite 545 on mine, had some nasty leaks and it cured them.

Hands down loctite 545. I agree the price is absurd.

I used Loctite 565, worked good, expensive too but a little tube goes a long way.

Always used teflon tape ,never had an issue.

Teflon tape doesn't seal, it works to condition the threads. It might seal, but that's not the job it was designed to do.

[ecgate]

Jimmydean is correct. Teflon tape is not meant to be used as a seal. Its so your threads don't grind together (steel on steel) when tightening your joint or connection. It act's as a lube.

Used some Loctite 545 today to seal an oil line, but I usually use teflon tape. I was impressed with the job the 545 did though and will probably use it more often

This,...

[JellyBeanDriver]

White Seal pipe sealant with teflon.

[BR3W CITY]

I just use the Napa branded "Liquid Tef". Apply a thin layer, let it tack up, screw together and your good to go. Did my last couple air-related projects that way, and I use it on all my air tools.

I will admit it, I am the 1 teflon tape vote, I am such a looser! I guess I better go to the store get some 545 so I can expand my collection of Loctite products.

[shawno72]

Guess I'll be buying some 545

Fastenal sells it,...

Go to any auto parts store and ask for it by name. They can get it for you. It is the recommended air fitting sealant for most manufactures. Mine was ordered from a NAPA I think.

[72BlckButy]

Just have to say... Loctite 545 is a great product.


That is all.

My first go around I used Teflon tape, since the fittings already had it. Slow leaks. This last time I used 545 on the tape, and it rocks. It may be expensive, but I hate doing things twice.

I work in a natural gas plant and teflon tape is what we use on just about everything. It seals great, and keeps threads from seizing up over the years. I work with anywhere from 800 - 1200 PSI. I reckon if it will seal that reliably, and for years on end, it will work with a 200 PSI air system.
The trick is getting it on correctly. Gotta wrap it tight and in the right direction.
