|In response to Re: Plumber's Putty Instead of Pipe Joint Compound|
I feel strongly that Teflon tape is the best. On plastic parts (not your case) any petroleum in the compound eventually attacks the plastic. On rare occasions, it also fails in metal joints - maybe by washing out. Is there a reason why you do not want to use tape?
Compound should only be used on tapered pipe threads where the seal is created by an increasing interference fit. Flare fittings and compression fittings rely on the development of intimate metal-to-metal contact over a small area to seal. I frequently see these fail when compound or tape is used, as it only interferes with the intended contact between surfaces and may eventually wash out.
