Hi,
This question is so simple I almost hate to ask it! /forums/images/graemlins/blush.gif
Is it standard practice to use NPTF male hose ends to screw into NPSM female swivel fittings?
I know the NPTF is a taper thread and the NPSM is a straight thread. I have found one reference that states that " a properly chamfered NPTF male will also seal with a NPSM female." I wonder how one would be sure the NPTF end is "properly chamfered?"
I don't see even one NPSM male fitting in my Northern Tool catalog, so I am guessing the reason why is that everyone just uses NPTF males into NPSM swivel females.
It sort of goes against my grain to put a taper thread male into a straight thread female. But if it is proven to work then I won't argue with success.
Is this correct? /forums/images/graemlins/confused.gif
PS...I am in the learning process which I hope will lead to a T&T on my tractor... /forums/images/graemlins/cool.gif
