quick question about tape, teflon tape.

[focusedrage]

Gonna be putting together somethings in the upcoming weeks, was wondering if there is some magic thread sealent or tape that i have not heard about. i figured i would just use plumers teflon tape, but will that take the heat of a oil system?

What are you trying to use it for? You usually only use the teflon tape for any water line with threads.

well what part of the system (where) are you gonna be puttin the tape on??? curious why you think you might need the tape to help your seal on something that you havent started? teflon can help out many SMALL oil thread leaks. teflon tape is not made just for plumbers. YES it can take the heat, and can be used in many other type systems (fuel, air, ect.). Teflon tape is the magic sealant

If your using those -10 AN fittings to the oil cooler you were talking about on another thread, the fittings use a mating flange to seal. Sealing has nothing to do with the threads other than their placing compression on that flange. If you feel you have to put something on the threads then the recomendation is for liquid teflon. This was told to me by an AN fitting salesman. I haven't used it, so no personal experience with it.

Teflon tape is excellent for plumbing. In houses and lawn sprinklers.

Use automotive products in automobiles, particularly in the oiling system. For things like nipples into castings, Permatex Non-Hardening. Just a little on the threads, not enough to squooge out more than a pencil-lead's width- if you can wipe it off, it's not doing anything.

As terefic181 says, things like AN fittings, flare fittings and compression fittings don't need sealer- the design of the interface is its own sealing surface, and the threads aren't in contact with areas of leakage.

sorry i should have claifyed, i would use the tape on the npt part of the npt to an fittings, ill have to look into that sealent you mentioned ^^^ thanks.

You only need teflon tape for NPT fittings. Use the white tape with the green tint for natural gas/petro-chemical use.

THe white stuff will work perfectly fine. Why not use a little just in case? Do it right once or do it wrong twice.

I just don't like those little worms that Teflon gets cut into. Particularly in the oiling system.
