Question by: Daryl W on Jun 29, 2025, 6:15 PM
What thread types are on each end of this adapter, and will it work for converting between JIC and ORB fittings?
Answer by: Customer Support on Jul 1, 2025, 3:56 PM
One end is a 9/16-18 male JIC SAE 37-degree flare, and the other is a 1/2-20 male SAE O-ring boss. So yes, that's exactly what this fitting does, connects a JIC line to an ORB port. Both threads are built to SAE J514 spec, and the NBR O-ring on the ORB end handles the sealing, so you're not relying on thread contact alone to keep things tight.

I need a fitting that can handle some serious pressure. What's the max on this one?
Answer by: Customer Support on Aug 7, 2025, 6:42 AM
This adapter is rated for dynamic pressures up to 6,000 PSI, so it should hold up well in demanding hydraulic systems.
Question by: Terry W on Feb 18, 2026, 8:17 AM
got a hose end with a 9/16-18 JIC flare and the port on the block is 1/2-20 ORB. is this the straight adapter that ties those together?
Answer by: Customer Support on Feb 20, 2026, 7:56 AM
For that exact mix of ends, yes. One side is male JIC SAE 37 degree flare with 9/16-18 threads, and the other side is male SAE O-ring boss with 1/2-20 threads.
