Rector seal 5 BEST stuff to use. I use it on threaded plumbing AND 3000 psi hydraulic jack threads. NEVER had a leak in 25 years and does not seize the threads. Doug

Doug has it right. Pipe dope out performs teflon tape.
My preferences are teflon impregnated pipe dope. As it is the only lubricant that will allow stainless NPT fittings to thread correctly with out galling.
Pipe dope and teflon tape are not sealers but are friction reducers to allow NPT threads to be tightened correctly.
Pipe dope and Teflon tape are to be used only on NPT fittings.
