Customer Reviews (4.8 / 5 · 5 reviews)

Zoe ★★★★★

We use these for a hot oil-seal application that kept destroying cheaper o-rings, and the 80 durometer HNBR holds up perfectly at 300°F. The 7.225" ID fits our groove like a glove.

Claire ★★★★★

Finally found HNBR o-rings that can handle high heat without degrading. The 80 durometer feels exactly right for my application, nice and firm.

Brian ★★★★★

Installed these on a hydraulic cylinder and they seated perfectly with no binding. The 80 durometer feels just right for the high-pressure application, and they’ve held up fine through a couple of heat cycles so far.
