Manufactured by SSP Fittings Corp, this straight adapter is constructed from stainless steel for corrosion resistance in demanding hydraulic and fluid system environments. It connects a 3/8-18 Male NPT thread on one end to a 9/16-18 Male JIC 37-degree flare on the other, making it well-suited for joining NPT-ported components to JIC flare line assemblies without additional fittings. The 37-degree flare seating provides a reliable metal-to-metal seal at the JIC connection, while the NPT thread relies on thread sealant applied during installation. With a 0.38-inch tube O.D. reference and a straight configuration, this adapter suits compact inline installations where thread conversion is needed between these two standard thread types.

Question by: Janet W on Nov 25, 2025, 8:55 AM
trying to hook a JIC hose up to a port that’s 3/8-18 NPT, is this the right little adapter for that?
Answer by: Customer Support on Nov 26, 2025, 3:41 PM
For converting between those two thread styles, it’s a straight stainless adapter with 3/8-18 male NPT on one end and 9/16-18 male JIC 37 degree flare on the other, so it’s meant for exactly that kind of NPT port to JIC flare line hookup.
