Male Npt X Fixed Female Bspp

Description & Features

Designed for connecting 1" Male NPT (1-11.5 NPTF) to 3/4" Fixed Female BSPP (G 3/4-14) threads, this straight steel adapter from Adaptall bridges two of the most widely used thread standards in hydraulic and industrial systems. The fixed female BSPP end provides a secure, non-swivel connection suited to installations where thread orientation is set at assembly.

Constructed from steel, the Male Npt X Fixed Female Bspp measures 35.5mm in length with a 35mm across-flats width, offering a compact profile for tight or space-constrained installations. The straight configuration keeps routing clean and direct where in-line thread conversion is required between NPT and BSPP-ported equipment or components.

Got a piece of equipment with a 3/4" BSPP port on it and need to tie into some 1" NPT fittings on the line. This straight adapter gonna work for that hookup?

Answer by: Customer Support on Jul 9, 2025, 6:42 AM

That's exactly what this fitting is built for. One end is 1" Male NPT running 1-11.5 NPTF threads, and the other is a 3/4" Fixed Female BSPP at G 3/4-14. So yeah, it bridges those two thread standards in a straight inline configuration without any routing gymnastics. The fixed female BSPP end does not swivel, so you'll want your port orientation sorted out before you wrench it down.

Yes, this straight adapter is designed to connect a 1" Male NPT to a 3/4" Fixed Female BSPP thread.
