Ask A Question

Description & Features

A straight union adapter with identical Male JIC SAE 37-degree flare connections on both ends, this Brennan Industries fitting is built for inline connections where thread continuity must be maintained without changing connection type or orientation. Both threads are sized at 3-1/2-12 and conform to SAE J514, making it suitable for use in high-pressure hydraulic circuits where standardized flare fittings are specified.

Constructed from straight steel, the Brennan Adapter is part of Brennan's 2403 Series and carries an overall length of approximately 2.400 mm. Its symmetrical configuration simplifies installation in applications where both mating ports share the same Male JIC thread specification. California residents should note that this product is subject to Prop 65 requirements.

Just want to make sure, this is a straight adapter, right? Both ends the same?
Answer by: Customer Support on Jun 11, 2025, 3:34 PM
That's correct. It's a straight union adapter with identical Male JIC SAE 37-degree flare connections on both ends, so it keeps everything in line without changing the connection type.
