Product Questions & Answers (2)

Question by: Daryl R on Nov 12, 2025, 9:28 PM

Will this fitting work for hooking up a hydraulic line to something with a 3/8-18 female NPT port? Just want to make sure before I order.

Answer by: Customer Support on Nov 14, 2025, 3:46 PM

This steel adapter is indeed designed to connect a 3/8-18 female NPT to a 5/16-24 male JIC 37-degree flare, so it should fit your described application.

Question by: Cindy H on Feb 7, 2026, 4:12 PM

got a 3/8 female NPT port on a small hydraulic block and need to run a JIC line off it, this the right adapter for that?

Answer by: Customer Support on Feb 9, 2026, 7:42 AM

For a 3/8-18 female NPT port feeding into a 5/16-24 male JIC 37 degree flare connection, yeah, that's exactly what this part bridges. The male JIC end is sized for tube with a 0.13 inch outer diameter, so as long as your JIC line matches up on that end, you're good. Steel construction and no thread sealant required on the JIC side, so it's built to hold up in higher-pressure hydraulic setups without any extra prep work on that flare end.
