Scarlett Q. ★★★★★

The temperature range is what sold me—I can run these up to 300°F without worrying about them melting or hardening. They seated nicely into the groove and the 90 durometer gives them a solid, firm feel that holds its shape during assembly.

Alexander A. ★★★★★

These fit perfectly in a high-temp hydraulic fitting I was repairing, and the 90 durometer gives them a reassuringly solid feel. They seated easily and haven't leaked a drop since installation.

Ava Y. ★★★★★

I needed a seal that could handle some heat cycling, and these 90 durometer HNBR rings fit the bill perfectly. The 1.109" inner diameter seated snugly in my compressor valve with no leaks on the first test.
