Product Questions & Answers

Seal's rated up to 5,000 PSI, is that the burst limit or the actual working pressure range for normal operation?

Question by: Billy B on Aug 9, 2025, 8:04 PM

That 0 to 5,000 PSI range reflects the working pressure this seal is built to handle in regular hydraulic service, not a burst or peak spike rating. The glass-filled PTFE construction paired with the rubber energizer keeps the seal functional across that full range, so you're not having to derate it for everyday use.
