Question by: Peggy S on Apr 4, 2026, 11:51 AM

Got a machine running NPT fittings on one side and BSPP on the other, will this adapter bridge that gap without needing anything else in between?

Answer by: Customer Support on Apr 6, 2026, 11:08 AM

That's what this one's built for. One end is a 1-1/2" male NPT with 11.5 NPTF thread, and the other is a 1-1/4" fixed female BSPP with an 11-thread pitch. So you're going straight from NPT to BSPP in a single fitting, no extra pieces required. Just make sure your mating ports match those sizes and thread counts before you order.

trying to hook up a npt line to a bsp fitting, is this the right adapter for that?

For bridging those two thread standards, it gives you a 1-1/2 inch male NPTF end (11.5 thread) on one side and a fixed 1-1/4 inch female BSPP end (G 1-1/4, 11 thread) on the other, in a straight steel adapter.
