Product Questions & Answers

Trying to hook a 3/8-18 female NPT port up to a 1/4-18 male NPT line, is this the right straight adapter?
Question by: Clint G on Aug 17, 2025, 9:27 AM
For that thread change, it matches up as a straight brass pipe adapter with 3/8-18 female NPTF on one end and 1/4-18 male NPTF on the other.

fits a 3/8 female NPT to a 1/4 male NPT, that right? just want to make sure before i order
Question by: Stan H on Mar 9, 2026, 11:03 AM
That's what it does. The female end is 3/8-18 NPT and the male end steps down to 1/4-18 NPT, so it reduces from the larger port to the smaller one in a straight configuration. Both ends use NPTF threads, which gives you a tighter, more leak-resistant connection than standard NPT alone.

got a manifold port that’s 3/8-18 female npt and i need to step it down to a 1/4-18 male npt. is that what this adapter does
Question by: Janice A on Sep 26, 2025, 7:18 AM
Function-wise, it is a straight brass adapter that goes from 3/8-18 Female NPT on one end to 1/4-18 Male NPT on the other, with NPTF threads on both sides for a tight, leak-resistant fit.

Will this adapter hold up okay if I'm using it with hydraulic systems?
Question by: Eddie B on Aug 21, 2025, 5:34 PM
This adapter is designed to work reliably in hydraulic systems, as well as grease, refrigeration, and instrumentation applications.
