Male Bspt X Female Bspp

Description & Features

Constructed from steel in a straight configuration, this adapter connects a 3/8" male BSPT thread (R 3/8-19) on one end to a 1/4" female BSPP thread (G 1/4-19) on the other, making it a practical solution for transitioning between tapered and parallel British Standard thread forms within hydraulic circuits. The straight body measures 22mm in length with a 17.5mm CH wrench width, allowing straightforward installation with standard tooling.

The Male Bspt X Female BSPP adapter is an Adaptall product, suited for applications where a size reduction or thread-form change is required between components. The steel construction provides durability appropriate for hydraulic line connections where consistent thread engagement and sealing integrity are expected.

Will this fitting work to connect a 3/8" BSPT male fitting to a 1/4" BSPP female fitting?

Yes, this adapter is specifically designed to connect a 3/8" male BSPT thread to a 1/4" female BSPP thread. It's a straight adapter made of steel.

Got a 3/8 BSPT male fitting on a hydraulic component and need to tie into a 1/4 BSPP female port, this the right adapter for that?

Answer by: Customer Support on Dec 30, 2025, 11:41 AM

That's exactly what this one's built for. One end is a 3/8" male BSPT (R 3/8-19) and the other is a 1/4" female BSPP (G 1/4-19), so it handles both the thread form change and the size step-down in a single straight fitting. Steel construction, 22mm long, and takes a 17.5mm wrench if you're torquing it in with standard hand tools.

got a fitting with R 3/8-19 on one side and i need to land it into a G 1/4-19 port, is that what this adapter’s for

For swapping between British Standard thread forms, this one goes from a 3/8 inch male BSPT (R 3/8-19, tapered) to a 1/4 inch female BSPP (G 1/4-19, parallel). It is a straight steel adapter meant for exactly that thread change and size reduction in a hydraulic connection.
