#2 X #2 MJIC UNION

Description & Features

Designed for straight inline connections in hydraulic lines, the #2 X #2 MJIC Union is a steel fitting that joins two Male JIC SAE 37-degree flare ends of the same size. Both threaded ends conform to SAE J514 and measure 5/16-24, making this a symmetric union suited for #2 JIC tubing assemblies where a direct male-to-male connection is required.

Manufactured by Brennan Industries from straight steel construction, this fitting carries a maximum dynamic pressure rating of 7,500 PSI. With an overall length of 1.170 mm, it is compact enough for installations where space is a consideration. California residents should note that this product is subject to a Proposition 65 warning.

Question by: Larry M on May 27, 2025, 9:23 AM

Got two male JIC ends that need joining up and ain't got a female coupler in the mix, this the right piece for that situation?

Answer by: Customer Support on May 29, 2025, 6:47 AM

That's what this union is built for. Both ends are 5/16-24 male JIC with a 37-degree flare, so it bridges two male fittings of the same size without needing a female connection in between. As long as you're working with #2 JIC tubing on both sides, this is your part.

Question by: Shawn R on Mar 22, 2026, 5:32 PM

got two #2 JIC hoses with 5/16-24 ends. is this the little union that’ll tie em together straight?

Answer by: Customer Support on Mar 24, 2026, 12:57 PM

For a straight inline hook-up, it joins two same-size Male JIC SAE 37 degree flare ends. Both sides are 5/16-24 threads and built to SAE J514, so it matches a #2 JIC male-to-male connection.
