Product Questions & Answers

Got a 3/4 inch male NPT line I need to knock down to a 1/2 inch female NPT port. This the right piece for that?

Question by: Troy B on Aug 12, 2025, 2:28 PM

That's what this adapter is built for. One end is 3/4-14 male NPT and the other is 1/2-14 female NPT, so it steps down the thread size in a straight, rigid configuration. Steel construction means it'll hold up in industrial use without any fuss.

Reckon this adapter would work alright for hooking up a pressure gauge to a hydraulic pump?

Question by: Rod H on Apr 8, 2025, 4:25 PM

This adapter is designed to provide a reliable pipe-to-pipe connection, making it suitable for connecting a pressure gauge to a hydraulic pump, given the correct NPT thread sizes.

got a line that’s 3/4-14 male npt and i need to step it down to 1/2-14 female. is that exactly what this adapter does

Question by: Hubert J on May 16, 2025, 2:26 PM

For stepping one NPT size down, it’s a straight pipe to pipe adapter with 3/4-14 Male NPT on one end and 1/2-14 Female NPT on the other, so it matches that male to female NPT thread change.
