Question by: Howard P on Jul 26, 2025, 7:43 AM
got a hose end that’s 1/4-18 nptf and the port on the block is g 3/8-19, is this the right adapter to marry those up?
Answer by: Customer Support on Jul 28, 2025, 7:10 AM
For connecting those two thread types, this fitting matches up as 1/4 inch male NPT with a 1/4-18 NPTF callout on one end, and a 3/8 fixed female BSPP with a G 3/8-19 callout on the other.
Question by: Cindy P on Jan 24, 2026, 7:55 AM
Got a machine running 1/4" NPT fittings on one end and 3/8 BSPP on the other, this the right adapter to tie them together?
Answer by: Customer Support on Jan 25, 2026, 8:23 PM
That's exactly what this fitting handles. One end is a 1/4" male NPT, threaded to the 1/4-18 NPTF standard, and the other is a 3/8" fixed female BSPP with a G 3/8-19 thread. If your ports match those specs, this adapter bridges the two without any modification needed.
