Question by: Eddie R on Jul 23, 2025, 2:06 PM

Got a system running G 1/4 BSPP on one end and NPT on the other, this adapter gonna bridge that gap straight-line without needing extra fittings?

Answer by: Customer Support on Jul 25, 2025, 7:14 AM

That's what it's built for. One side is 1/2-14 NPTF male, the other is G 1/4-19 BSPP female, so it connects those two thread standards in a single straight fitting. No extra couplings needed. The straight shape keeps the hydraulic connections clean, and at 25.5mm long and 22mm wide, it fits into tighter spots without much trouble. Steel construction means it holds up in typical hydraulic line work.

Will this here adapter work to hook up a 1/2" NPT male fitting to a 1/4" BSPP female port?

Answer by: Customer Support on Aug 2, 2025, 8:52 AM

Yes sir, it will. This adapter is made to connect exactly those sizes and thread types, going from a 1/2" NPT male to a 1/4" BSPP female.

got a hose end that’s 1/2-14 nptf and the port on my valve is g 1/4-19 bspp. is this the right little adapter to marry those up?

Answer by: Customer Support on Mar 17, 2026, 7:35 AM

For tying those two thread styles together, it matches exactly: one side is 1/2 - 14 NPTF male and the other side is G 1/4 - 19 BSPP female, in a straight steel adapter.
