Description & Features

A straight steel hydraulic adapter connecting a 1-5/16-12 Male JIC SAE 37-degree flare on one end to a 1-1/16-12 Female JIC swivel 37-degree flare on the other, the 16MJ-12FJS is manufactured by Brennan Industries to SAE J514 standards on both threads. The swivel end allows for rotational adjustment during installation, reducing stress on connected lines and simplifying alignment in tight or fixed-position assemblies.

Built from straight steel, this Series 6504 adapter is suited for hydraulic line connections where a reliable JIC-to-JIC size transition is required. The overall length measures 2.450 inches, with a hex size of 1.500 inches for wrench engagement. Both thread ends conform to SAE J514, making this fitting compatible with standard JIC hydraulic systems across a range of industrial equipment and machinery.

Question by: Janice W on May 5, 2025, 8:48 PM
Just want to make sure this will fit my setup. I've got a 1-5/16-12 male end and need to connect it to a 1-1/16-12 female swivel. This adapter should do the trick, right?

This straight steel adapter is designed to connect exactly those sizes – a 1-5/16-12 male JIC to a 1-1/16-12 female JIC swivel. It's built to SAE J514 standards, so it should fit right into your existing JIC hydraulic system.
