trying to hook a 7/16-20 JIC line to a 3/8-18 pipe port. is that what this fitting does?
Answer by: Customer Support on Aug 26, 2025, 9:11 AM
It adapts a 7/16-20 male JIC SAE 37 degree flare on one end (SAE J514) to a 3/8-18 male NPTF on the other end (SAE J476), in a straight steel body.

Will this fitting hold up if I'm pushin' close to that 6,000 PSI? Don't want no blowouts.
Answer by: Customer Support on Apr 3, 2026, 9:35 AM
For dynamic applications, this straight adapter is rated to a maximum pressure of 6,000 PSI, so you should be good to go if you stay at or below that level.
Question by: Lyle C on Mar 11, 2026, 2:50 PM
Running 6,000 psi through this thing gonna be an issue, or is that its actual rated limit?
Answer by: Customer Support on Mar 13, 2026, 6:10 AM
6,000 psi is the maximum dynamic pressure rating on this adapter, so that's the ceiling for pressurized operation. As long as your system stays at or below that, you're well within spec for a standard hydraulic setup.
