Customer Reviews (4.6 / 5 · 5 reviews)

George ★★★★★

The 50-durometer material made these o-rings much more pliable than the harder ones I've used before, and they seated easily into the groove on my hydraulic cylinder. Replaced a worn seal in about five minutes, and the pack of 80 gives me plenty of spares for future projects.

Hazel U. ★★★★★

These fit perfectly on my shop press ram, and the 50-durometer rubber sealed the leak on the first try without being too stiff.

Riley W. ★★★★★

Had a small hydraulic leak on a cold morning and these handled it fine, even down near the freezing mark. The -40°F rating gave me confidence, and the 50 durometer made seating them in the groove a lot easier than the stiffer ones I've used.
