Hey, I need a stainless fitting for some hydraulic lines. This here is just the nut, right?

Answer by: Customer Support on Nov 18, 2025, 5:12 PM

That's correct. This stainless steel fitting is just the female JIC 37-degree flare nut, designed for use with 1.25-inch OD tubing. You'll need the mating sleeve and fitting body to complete the connection.

Got a 1-1/4 inch OD tube line I'm trying to cap off with a JIC fitting, this the right nut for that?

Answer by: Customer Support on Aug 30, 2025, 4:06 PM

For 1.25-inch OD tubing with a JIC connection, yeah, this is the one. It's a female JIC 37-degree flare nut built specifically for that tube size, and the thread is 1-5/8-12, which is standard for this tube OD in JIC applications. The 37-degree flare seats metal-to-metal, so you get a solid seal without relying on any gasket or extra sealing material.
