What's the max pressure this cap nut can hold before it starts giving out?

Answer by: Customer Support on Aug 14, 2025, 4:49 PM

Rated at 6,000 psi dynamic pressure, so it holds up well in most high-pressure hydraulic lines you'd run into on the job. That rating follows SAE J514 spec, which is a widely used standard for JIC fittings. As long as you're staying within that pressure range, it should serve you just fine.
