Question by: Chad R on Aug 31, 2025, 8:06 PM
Got a 1" BSPT male fitting on a hydraulic line and need to tie into some NPT female ports on a manifold block. This the right adapter for that?
Answer by: Customer Support on Sep 2, 2025, 6:21 AM
That's what this one's built for. The male side carries a 1" BSPT R 1-11 thread and the female side accepts 1" NPTF at 1-11.5 threads per inch, so you're bridging those two thread standards in a straight inline configuration. Both sides are the same nominal size, so there's no reduction happening here. Steel construction holds up well in hydraulic environments where you've got pressure and movement working against your fittings over time.
