Product Questions & Answers (3)
Question by: Hugh B on Jul 22, 2025, 2:38 PM
Will this fitting work with standard NPT threads?
Answer by: Customer Support on Jul 24, 2025, 6:00 AM
It's designed with one NPTF end, which should be compatible with standard NPT threads. The other end is NPSM.
Question by: Vince P on Aug 13, 2025, 6:01 AM
does this adapter work going from a 3/8 female swivel on one end to a 1/2 female pipe thread on the other, or did i get that backwards?
Answer by: Customer Support on Aug 14, 2025, 11:59 AM
You've got it right. One end is a 3/8 NPSM female swivel connection and the other is a 1/2 NPTF female pipe thread. That straight configuration lets you join those two thread types without additional fittings in between.
Question by: Hugh R on Dec 30, 2025, 11:27 AM
got a 3/8 female swivel on one side and need to tie into 1/2 pipe thread, is this the right adapter?
Answer by: Customer Support on Dec 31, 2025, 6:10 PM
For that kind of hook-up, this adapter matches a 3/8 NPSM female swivel end on one side and a 1/2 NPTF female pipe thread on the other. It is a straight adapter, so it keeps the connection in-line.
