Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

Been running these in a hydraulic pump assembly where standard nitrile would swell up, and the HNBR handles the heat and oil exposure much better. So far no leaks after a few hundred cycles at 200°F.

Riley U. ★★★★★

Been using these in a pneumatic cylinder rebuild and the 90 durometer holds up perfectly under constant 150psi cycling. The temperature range gives me confidence for both cold starts and sustained heat.

Kevin ★★★★★

The dash 222 size is spot on for my application, and the 90 durometer feels reassuringly stiff. These HNBR rings handled a week of steam exposure without any swelling, and the -40°F rating gives me confidence for winter storage.
