Will this fitting hold up in a hydraulic system running at 5000 PSI?
Answer by: Customer Support on Oct 24, 2025, 1:38 PM
This fitting is rated for a maximum dynamic pressure of 6,000 PSI, so it should handle that pressure without issue.
Question by: Neil F on Jan 30, 2026, 12:21 PM
got a hose end with a 9/16-18 JIC flare on it. will this fitting screw right on and seal up?
Answer by: Customer Support on Jan 31, 2026, 3:02 PM
With a 9/16-18 male JIC SAE 37 degree flare on the B1 side, this fitting matches that thread and flare style. The other end is a 7/16-20 male SAE O-ring boss, and it uses an NBR O-ring for sealing on the ORB side.
