12FJ-20MJ STRAIGHT REDUCER

Description & Features

A straight steel reducer fitting designed to transition between two JIC 37-degree flare connections of different sizes, the 12FJ-20MJ Straight Reducer from Brennan Industries handles common size reduction needs in hydraulic line assemblies. The female end threads to a 1-1/16-12 JIC connection, while the male end accepts a 1-5/8-12 JIC connection, both conforming to SAE J514. This one-piece rigid construction keeps the fitting compact and eliminates potential leak points associated with multi-piece adapters.

Manufactured from straight steel, this fitting suits hydraulic systems where a direct inline size transition is required without angular offset. The Brennan Series 2406 designation identifies it as part of a standardized straight reducer line, making cross-referencing with compatible components straightforward. California residents should note that this product is subject to Proposition 65 warning requirements.

Reckon this'll fit right where I'm swapping out a busted reducer with those JIC flare connections?

Context-first, this straight reducer is made to transition between two JIC 37-degree flare connections of different sizes, so as long as your connections match the 1-1/16-12 JIC female and 1-5/8-12 JIC male sizes, it should be a direct replacement.
