Henry ★★★★★

I needed a size 433 for a hydraulic repair and these fit perfectly. They handle the higher temps in my system without any issue, a solid upgrade from standard nitrile.

Penelope L. ★★★★★

The 80 durometer hardness is spot on for my application, and the -40°F low-temp rating gives me peace of mind for winter use. I’ve bought cheaper packs before, but these five just feel denser and more consistent out of the bag. Already reordering a few more sets.

Violet ★★★★★

The 80 durometer rating is spot on—these HNBR rings feel firm but still seated easily into the groove. I've been running them in a hot oil application right at the 300°F edge and they've held up without any hardening after a week of use.
