Emily ★★★★★

The 0.21" cross-section fit my hydraulic cylinder perfectly, and these FKM rings seal tight against the hot oil without any softening. I've tested them up to 350°F so far with zero leaks.

Zoe X. ★★★★★

Ordered these for a high-temp compressor rebuild and the 400°F rating gives me confidence they'll hold up. Fit perfectly on the shaft and no leaks after a full day of running. Exactly what I needed for the job.

Charlotte ★★★★★

Had a stubborn hydraulic leak that standard Buna rings couldn't handle, and these Viton FKM o-rings sealed it perfectly even with the heat. The 75 durometer feels firm but still flexible enough to install easily.
