Product Questions & Answers (2)

Question by: Rusty Y on Apr 16, 2025, 11:40 AM
got a 1/2-14 nptf male port but my gauge line is 3/8-18 nptf female, is this the right bushing to step it down?
Answer by: Customer Support on Apr 17, 2025, 6:01 PM
For that thread combo, yes. It is a steel pipe-to-pipe bushing with 1/2-14 male NPTF on one end and 3/8-18 female NPTF on the other, so it adapts a 1/2-14 female NPTF port down to accept a 3/8-18 male NPTF fitting.
Question by: Roger A on Jan 25, 2026, 9:38 AM
i got a valve body with 1/2 npt on it, but the gauge i’m trying to run is 3/8 npt. is this the bushing that’ll step it down?
Answer by: Customer Support on Jan 26, 2026, 3:45 PM
For that kind of size change, yes. This is a 2081 Series steel reducer adapter with 1/2-14 male NPT on the outside and 3/8-18 female NPT on the inside, so it lets you go from a 1/2 NPT female port down to a 3/8 NPT male connection.
