Steel Adapter, 1-11-1/2 Female NPT To 1-5/16-12 Male JIC 37 deg Flare, 45 deg Elbow

Description & Features

Designed for installations requiring a directional change at the connection point, this Steel Adapter, 1-11-1/2 Female NPT To 1-5/16-12 Male JIC 37 deg Flare, 45 deg Elbow transitions between a 1-11/2 female NPT port and a 1-5/16-12 male JIC 37° flare fitting at a 45-degree angle. The elbow configuration allows routing adjustments in tight or angled assemblies where a straight adapter would not be practical.

Manufactured in steel and sourced from Brennan Industries, this adapter carries catalog number C1EF57 and suits hydraulic lines working with 1-inch tube OD connections. The JIC 37° flare end conforms to standard SAE flare fitting geometry, ensuring broad compatibility with hydraulic components using that thread form. The female NPT end provides a reliable threaded pipe connection on the inlet side.

Question by: Stan K on Jun 3, 2025, 5:02 PM

Will this elbow adapter work to connect a 1 5/16-12 male JIC to a 1-11 1/2 female NPT?

Answer by: Customer Support on Jun 5, 2025, 6:10 AM

Yes, this steel adapter is specifically made to connect those two thread types at a 45-degree angle.

Question by: Wes H on May 3, 2025, 8:58 PM

does this fit up to a 1 inch tube line on the JIC side or is that measurement somethin different

Answer by: Customer Support on May 5, 2025, 4:52 PM

The male JIC end on this fitting is sized for 1-inch OD tubing. The 1-5/16-12 thread spec confirms that, since JIC fittings are sized by the tube OD they're meant to mate with. So if you're running 1-inch steel tubing with a 37-degree flare, this is the right end for that connection.

Question by: Rhonda H on Dec 27, 2025, 6:07 PM

trying to replace a fitting, is this the one that goes from 1-11-1/2 female npt over to a 1-5/16-12 male jic with a 45 elbow?

Answer by: Customer Support on Dec 29, 2025, 6:33 AM

Match up the two ends and the bend. This adapter has a 1-11-1/2 female NPT on one side and a 1-5/16-12 male JIC 37 degree flare on the other, and it is built as a 45 degree elbow.
