The other day I bought a 1-oz tube of Harvey's Faucet and Valve

I can imagine several plumbing applications for it. Has anyone used
grease instead of teflon tape?

@J Burns:

In what application ?

Using teflon tape on threaded pipe fittings to provide an extra level
of
sealant in the threads is the primary application of teflon tape...

In some applications like gas piping, pipe dope is required in place
of using teflon tape...

The avowed purpose of Teflon tape is to make threading the pipe easier by
providing a slippery surface. It is the deformation of the threads that
provides the sealing of the joint.

Teflon tape does provide SOME sealing, but can't be counted on to provide a
complete one. If it did, pipe dope would not be required for certain
application.



Hey Bub-

Why do you insist on spreading this wrong information?

"avowed purpose of Teflon tape is to make threading the pipe easier
by providing a slippery surface. It is the deformation of the threads

In several previous A.H.R threads it was clearly established
that........
NPT threads DO NOT SEAL BY THREAD DEFORMATION.

The design & mfr of the threads create a spiral leak path between the
thread crests and valleys.
NPT threads, correctly cut, MUST HAVE A SEALANT TO NOT LEAK.

Only NPTF threads (dry seal) depend on thread deformation to seal.

I am amazed by your inability to absorb new information to replace
wrong information.
