Kevin ★★★★★

The -40°F to +300°F range gives me peace of mind for outdoor equipment that sits in extreme temps. The 80 durometer feels firm but not brittle, and the 8.975" ID seated snugly on the flange with zero effort.

Hannah E. ★★★★★

These o-rings fit perfectly on my hydraulic cylinder cap, handling the 300°F operating temperature without any softening. The 80 durometer hardness gives a nice, firm seal without needing to over-tighten.

Hannah B. ★★★★☆

Clamped these into a hydraulic setup and the 0.21" cross-section seated nicely without any rolling. The 80 durometer feels firm enough for the pressure I’m running, though I wish the pack came with a few more spares for the price.
