Christopher G. ★★★★★

These o-rings fit perfectly into the groove on my hydraulic cylinder and sealed the leak immediately. The 250°F temperature rating gives me confidence they'll hold up in my application.

Emma Z. ★★★★★

The 70 durometer hardness is spot on for my application, and the -40°F rating gives me peace of mind for outdoor use in winter. Package of 18 is plenty for a few projects. Fit the groove perfectly, no leaks on the first try.

Benjamin G. ★★★★★

Just replaced the worn seals on my old pneumatic actuator with these, and the -40°F rating gives me confidence for winter use. The 70 durometer feels firm enough to hold pressure without being too stiff to install.
