Question by: Johnny H on Feb 20, 2026, 7:36 PM
Got a 1-inch BSPT male fitting on my hydraulic line and need to step it down to a 3/4 NPTF female connection. this the right adapter for that?
Answer by: Customer Support on Feb 22, 2026, 4:35 PM
That's what this one's built for. The male side is a 1-inch BSPT thread (R 1 - 11 callout) and the female side is 3/4-inch NPTF (3/4 - 14 NPTF callout), so it bridges those two thread standards in a straight configuration. It's made by Adaptall out of steel, so it holds up well in typical industrial hydraulic setups. Should drop right in where you need it.

trying to hook a 1-inch BSPT male line into a 3/4 NPTF port, is that what this adapter is for?
Answer by: Customer Support on Mar 6, 2026, 11:50 AM
Built for thread conversion, it connects a 1 inch BSPT male end (R 1-11) to a 3/4 inch NPTF female end (3/4-14 NPTF) in a straight steel adapter.
