Got a hydraulic line running BSPP fittings on one end and NPT on the other, will this adapter actually bridge them two without needing extra stuff in between?

Answer by: Customer Support on Apr 1, 2026, 4:58 PM

That's what it's built for. One side is a male G 1/8 - 28 BSPP thread and the other is a female 1/4 - 18 NPTF thread, so it connects those two standards directly in a single fitting. No additional adapters needed between the two thread types. The stainless steel construction holds up well in industrial fluid transfer setups, and the straight profile keeps things clean and compact at 32.1mm long.

got a male G 1/8 - 28 port on one side and need to land a 1/4 - 18 NPTF female on the other. is that what this adapter does?

Answer by: Customer Support on Jun 29, 2025, 6:24 AM

For tying two thread styles together, it converts a male BSPP on Side 1 (G 1/8 - 28) over to a female NPTF on Side 2 (1/4 - 18).
