Hannah ★★★★★

The 70 durometer hardness feels just right for my application—firm enough to hold a seal but not brittle when I stretched one into place. Handled the high-temp side of that -15°F to +400°F range without any visible wear after a few weeks of use. Exactly the size I needed, and the pack of 13 is a sol

Robert L. ★★★★★

These fit perfectly on my old hydraulic cylinder and the 70 durometer feels like the right balance between flexibility and sealing pressure. They’re holding up well under the heat near my engine.

Charlotte F. ★★★★★

I needed o-rings that could handle high-temp applications, and these viton ones seal perfectly at 400°F without any issue. The 0.139" cross-section fits snugly into my groove, and the 13-pack is enough for a few rebuilds.
