Product Questions & Answers

What kinda pressure can this lil' seal handle? I'm usin' it in a hydraulic system that can get pretty cranked up.
Question by: Denise W on Nov 30, 2025, 8:46 PM
It's rated to handle pressures from 0 to 1,000 PSI, so it should hold up under decent pressure.

What kind of temps can this seal hold up in? Got equipment runnin hot and cold both, need somethin that won't give out on me.
Question by: Howard W on Oct 7, 2025, 9:34 PM
Buna-N handles a pretty wide swing. This U-seal is rated from -40°F all the way up to 250°F, so it can take both ends of that range without breaking down. As long as your system stays within those bounds, you should be in good shape.
