runs up to 10,000 PSI on our press cylinders, that within range for this seal?

Answer by: Customer Support on Sep 9, 2025, 6:54 AM

10,000 PSI is right at the top end of what this seal is rated for, so you're covered. The pressure range runs from 0 all the way up to 10,000 PSI, and the Buna-N rubber construction with hard plastic back-up rings handles that load without issue. Just make sure you're not regularly spiking above that ceiling and you'll be in good shape.
