Will this here fitting work to connect somethin' with a BSPP thread to somethin' with an NPT thread?

Yes, this adapter is designed to connect a male NPT end to a fixed female BSPP end, which allows connection between different thread types in hydraulic applications.
Question by: Lynn B on Jan 8, 2026, 4:39 PM
Got a 1/2" NPT male fitting on my hydraulic line and need to tie into something with a 3/8" BSPP female port. This the right adapter for that?
Answer by: Customer Support on Jan 10, 2026, 6:08 AM
Yeah, that's exactly what this one does. One end is 1/2" male NPT with a 1/2-14 NPTF thread spec, and the other end is 3/8" fixed female BSPP running a G 3/8-19 thread. Straight body, steel construction, so it holds up well in standard hydraulic hydraulic connections setups where you're bridging those two thread standards.
