Product Questions & Answers

got a line running 3/8 BSPP and need to drop it down to a 1/4 BSPP port on a valve block, this the right piece for that?
Question by: Billy W on Jul 19, 2025, 4:28 PM
That's what this adapter is built for. One end is 3/8-19 male BSPP and the other is 1/4-19 male BSPP, both parallel thread, straight configuration. So if you're stepping down between those two sizes on a male-to-male connection, this fits the bill without any modification needed.

Will this adapter work to connect a 3/8" BSPP fitting to a 1/4" BSPP fitting?

Absolutely. This adapter is specifically designed to connect a 3/8-19 male BSPP fitting to a 1/4-19 male BSPP fitting.

trying to tie a 3/8-19 male BSPP port into a 1/4-19 male BSPP setup, is that what this straight union does?
Question by: Melvin F on Aug 18, 2025, 2:07 PM
Built to connect two different male BSPP thread sizes in a straight line, it adapts from 3/8-19 male BSPP on one end to 1/4-19 male BSPP on the other for a direct, in-line connection.
