what's the max pressure rating on this cap nut? got a line running pretty hard and need to know if it'll hold up

Answer by: Customer Support on May 5, 2025, 8:01 PM

Rated to 7,500 PSI dynamic pressure, so it can handle demanding hydraulic lines without issue. That's a solid working rating for most high-pressure applications you'd run into.
