Product Questions & Answers

Got a piece of equipment with a 1/4" BSPP male port and I need to tie into 3/8" female NPT line, this the right adapter for that?
Question by: Ralph A on Nov 14, 2025, 12:51 PM
That's what this fitting is built for. One end is 1/4" male BSPP (G 1/4 - 19 thread) and the other is 3/8" female NPT (3/8 - 18 NPTF). Steel construction, straight configuration, so there's no angle to account for when you're routing your line. Wrench flat comes in at 22mm, and the overall length is just under 35mm, so it's pretty compact if clearance is tight.

It bridges those two thread styles in a straight steel adapter, with a 1/4 inch male BSPP on Side 1 (G 1/4 - 19) and a 3/8 inch female NPTF on Side 2 (3/8 - 18 NPTF).
