Question by: Ralph T on Oct 16, 2025, 9:37 PM

trying to hook a pipe thread port up to a JIC line, is this the one that goes 1-11-1/2 female npt to 1-5/8-12 male jic?

Answer by: Customer Support on Oct 18, 2025, 3:21 PM

For connecting those two standards, it matches what you described. One side is a 1-11-1/2 Female NPT thread, and the other side is a 1-5/8-12 Male JIC 37 degree flare, in a straight adapter body.

Question by: Jean C on Dec 24, 2025, 9:57 PM

Got a line running 1-inch NPT female port on a manifold block and need to tie into a JIC system on the other end. This adapter gonna bridge that gap without me having to run a whole new line?

Answer by: Customer Support on Dec 26, 2025, 2:26 PM

That's exactly the scenario this fitting handles. The female NPT side is threaded 1-11/2, which covers a 1-inch nominal pipe connection, and the male JIC end runs 1-5/8-12 with a 37 degree flare seat. Both ends land on opposite sides of a straight body, so you get a clean inline transition with no bends or offsets. Steel construction means it holds up in working hydraulic environments, and the JIC flare interface seals mechanically, so no thread sealant needed on that end.
