What's the max pressure this adapter can handle without giving out?

Answer by: Customer Support on May 16, 2025, 10:06 AM

This adapter is rated for a maximum dynamic pressure of 5,000 psi, making it suitable for high-pressure hydraulic systems.

Question by: Dwight C on Dec 11, 2025, 9:17 PM

does this adapter work with standard 5/16-24 JIC fittings on both sides, or is one end different from the other?

Answer by: Customer Support on Dec 13, 2025, 6:17 AM

One end carries a male JIC 37-degree flare thread and the other is a male SAE O-ring boss thread, both sized at 5/16-24. So it bridges those two thread types rather than matching the same style on each end. Both ends conform to SAE J514, which keeps everything playing nice with standard hydraulic components built to that spec.
