Grace K. ★★★★★

The 90 durometer HNBR material handles high heat well, and the 2.234" ID was spot-on for my hydraulic fitting. They feel sturdier than standard Buna-N and haven't shown any wear after a few cycles.

Amelia M. ★★★★★

These O-rings fit perfectly into my high-temp pneumatic line, and the 90-durometer hardness handles the pressure without any deformation. The material feels much tougher than the standard Buna-N I used before.

Brian N. ★★★★★

I replaced the old seals in a hydraulic cylinder with these HNBR o-rings and the 90 durometer hardness made installation easy without tearing. They've held up perfectly under heat cycles up to 300°F.
