Some clarification for everyone trying to follow the preceding discussion:
1. I've been been primarily discussing pipe thread compound (aka pipe dope) while StingrayL82 has been focusing mostly on pipe thread tape. Two closely related but distinctly different materials with similar uses.
2. There are many types of hose/tubing/pipe fittings and connections, with distinct differences in appropriate uses. The thread compound and thread tape we've been discussing is only suitable for tapered NPT threads. Thread tape and thread compound is absolutely NOT suitable for use on other types of fittings and connections, such as flare nut or AN fittings.
