Matthew Y. ★★★★★

These HNBR o-rings are precisely the dash 235 size I needed for a high-temp application where standard Buna-N just wouldn't cut it. The 90 durometer is firm but installed without any trouble, and the -40°F to +300°F rating gives me confidence in the seal.

Edward ★★★★★

The 90 durometer HNBR feels robust, handled the 300°F pasteurization cycle without any noticeable swelling. These 0.139" cross-section rings seated perfectly in my 3.109" groove, saving me a second order.

Lily E. ★★★★★

I needed high-temp seals for an engine cover that kept warping, so I tried these HNBR o-rings. The 90 durometer feels sturdy, and they've held up perfectly in the 300°F environment with zero issues.
