Question by: Keith W on Aug 6, 2025, 8:48 PM

got a port that’s 1/8 G thread on a valve, will this adapter let me screw in a 1/4 nptf line?

On the BSPP side you get a fixed female G 1/8 - 28 thread, and the other end is a 1/4 - 18 NPTF male. It is a straight steel adapter meant to join those two thread types in one connection.

Got a line running 1/4 NPT male fittings on one end and need to tie into a 1/8 BSPP female port on a piece of equipment. this adapter work for that swap?

Answer by: Customer Support on Dec 16, 2025, 6:23 AM

That's exactly what this fitting is built for. One side is 1/4-18 NPTF male threading, the other is a G 1/8-28 fixed female BSPP. So if your existing line terminates in a 1/4 NPT male connection and your equipment has a 1/8 BSPP female port, this bridges that gap in a straight configuration without any additional adapters in between.
