Pipe fitting are tapered threads, it is the threads that seal, not the interface of the two ends. Pipe fittings are on the gas lines in your home.Thanks for all the replies
Sorry if I am being thick but can someone give me an example of a pipe fitting
From Mick Muck "AN fittings, no. Pipe fittings, yes."
Thanks again
Ok thanks got it nowPipe fitting are tapered threads, it is the threads that seal, not the interface of the two ends. Pipe fittings are on the gas lines in your home.
Yes, and often if an AN fitting leaks, it is because one of the tapered surfaces is galled. Sometimes, if you are lucky, you can get them to seal by "re-indexing" the male and female to give a different sealing surface. This is a "get by" fix, once galled they should have new ends.AN fittings also must be torqued to the correct amount. Make sure you do not over tighten them.
Curious how this Indexing actually works Since there is only one starting point to the threads on both male and female.. I must’ve missed something somewhere…Yes, and often if an AN fitting leaks, it is because one of the tapered surfaces is galled.

The end on a female fitting floats, you can index the hose. If it didn't float, the hose would twist as you tightened the fitting.Curious how this Indexing actually works Since there is only one starting point to the threads on both male and female.. I must’ve missed something somewhere…
