Evelyn ★★★★★

The 1.609" ID fits perfectly on my hydraulic cylinder rebuild kit, and the 90 durometer material feels much stiffer than the softer ones I've used before. I appreciate that they can handle up to 250°F, so I don't have to worry about heat degradation in my application.

Sophia B. ★★★★★

These 90-durometer o-rings feel much firmer than the standard 70 I've used before, which should hold up better in my hydraulic fittings. The bulk pack of 400 is exactly what I needed for rebuilding several valves.

Lucy J. ★★★★★

Finally found an o-ring that can handle the heat and cold swings in my hydraulic system without getting brittle. The 90 durometer feels really solid, and the bulk pack of 400 means I probably won’t need to reorder for a long time.
