Product Questions & Answers

got a port that’s 1-11-1/2 male npt and I need to step it down, is this the right bushing?

Question by: Rusty R on Nov 6, 2025, 11:38 AM

Built as a reducer adapter, it takes a 1-11-1/2 male NPT connection on one side and gives you a 3/4-14 female NPT on the other, so it’s meant for stepping down between those two NPT thread sizes.
