Sebastian T. ★★★★★

Needed to replace a gasket in an outdoor hydraulic cylinder and these 70 durometer rings seated perfectly. The -40°F rating gives me peace of mind for winter operation, and the bulk pack means I have spares for the next leak.

Richard N. ★★★★★

I needed these for a hydraulic repair and the 70 durometer hardness was exactly what the spec called for. The whole pack of 400 arrived sealed and clean, no burs or flashing. Solid o-rings for the price.

Joshua R. ★★★★★

The 2.989" ID fit perfectly on my pump flange, and the 70 durometer feels just right for our low-pressure water lines. I appreciate the -40°F lower limit, since our shop sometimes gets cold overnight.
