Andrew ★★★★★

Got the 20-pack and the 75 durometer hardness feels exactly right for sealing in my hot oil system—the -400°F upper limit gives me real peace of mind. These brown Viton rings seated snugly on the first try, no rolling or pinching.

Sophia ★★★★★

I've been using these FKM o-rings in a hydraulic press that sees high heat, and they hold up perfectly without any swelling. The 75 durometer feels just right—firm enough for sealing but not brittle. Really glad I found these in a 20-pack.

Alexander Y. ★★★★★

The high temperature rating up to 400°F gives me confidence using these in my engine bay, and the 75 durometer feels firm enough for a solid seal. Fit perfectly on my hydraulic fitting.
