Product Questions & Answers

got a 3/8-18 male pipe thread on my line and need to step it down, is this the bushing that goes to 1/4-18 female?

Question by: Lee H on Sep 15, 2025, 7:47 AM

With a 3/8-18 male NPTF on one side and a 1/4-18 female NPTF on the other, this bushing is meant to adapt between those two pipe thread sizes.

trying to step a line down, is this the bushing that goes from 3/8 npt male to 1/4 npt female?

Question by: Ronnie A on Aug 28, 2025, 12:54 PM

Function-wise, yes. It is a 2081 Series steel reducer bushing with 3/8-18 male NPT on the outside and 1/4-18 female NPT on the inside, so it lets you adapt from a larger NPT port to a smaller NPT connection.

Will this adapter work for hydraulic systems, or is it just for grease fittings and stuff like that?

Question by: Harvey C on Jun 25, 2025, 9:50 AM

It's suitable for hydraulic systems, as well as grease and instrumentation applications.
