Ask A Question

Description & Features

Designed for straight-line hydraulic connections, the 10MJ-16MORB Straight adapter from Brennan Industries bridges a 7/8-14 Male JIC SAE 37-degree flare (Thread B1) to a 1-5/16-12 Male SAE O-Ring Boss (Thread B2), with both threads conforming to SAE J514. Constructed from straight steel with an NBR O-ring seal, it is rated for dynamic pressures up to 4,000 PSI, making it well suited for demanding hydraulic systems in industrial and mobile equipment environments.

The NBR seal material provides reliable compatibility with standard petroleum-based hydraulic fluids. California residents should note that this product is subject to Proposition 65 warnings per Brennan Industries' compliance labeling.

Question by: Merle C on Dec 18, 2025, 9:08 PM
Got a port on my hydraulic manifold that's 1-5/16-12 ORB and I need to run a JIC line off it, this the right adapter for that?

That's what this one's for. One end is a 7/8-14 Male JIC 37-degree flare and the other is a 1-5/16-12 Male SAE O-Ring Boss, so it'll bridge those two thread types in a straight-line connection. Both threads conform to SAE J514, and the NBR o-ring on the ORB end handles the sealing. As long as your system runs standard petroleum-based hydraulic fluid and stays under 4,000 PSI dynamic pressure, this adapter fits the bill.

Will this here fitting hold up okay in a hydraulic system that runs pretty much all day, every day?
Answer by: Customer Support on Dec 10, 2025, 9:49 PM
With a dynamic pressure rating of up to 4,000 PSI, this adapter should be suitable for demanding hydraulic systems in industrial and mobile equipment, as long as you're using standard petroleum-based hydraulic fluids. The NBR O-ring is compatible with those.

got a hose end that’s 7/8-14 JIC male and i need to go into a 1-5/16-12 ORB port. is that what this adapter does
Answer by: Customer Support on Mar 27, 2026, 6:24 PM
For tying a 7/8-14 male JIC 37 degree flare connection to a 1-5/16-12 male SAE O-Ring Boss connection, this is the straight adapter built for that job. Both ends are SAE J514, and the ORB side seals with an NBR O-ring.
