There are other tapered pipe threads that will, such as NPTF, NPSF and NPSI. These are also known as dryseal pipe threads. The thread form for dryseal threads guarantees that the roots and crests make contact by the time the flanks come together. Unless you know which type you have, I would recommend a sealant on all tapered pipe thread connections. Chris Zavatson
