Description & Features

A straight hydraulic fitting designed to transition between a tube bore connection and a male JIC thread, the 12Bore-10MJ Straight from Brennan Industries suits inline hydraulic line connections requiring a reliable mechanical seal. The bore end accommodates a 3/4-inch to 5/8-inch tube OD, while the male JIC end features a 7/8-14 thread with a 37-degree flare conforming to SAE J514. This combination makes it well-suited for connecting tube assemblies to JIC-ported components in hydraulic circuits.

Constructed from straight steel, this Brennan Series 0403 fitting offers a compact profile with an overall length of 1.100 inches. California residents should note that this product is subject to a Proposition 65 warning per Brennan Industries' compliance labeling.
