Miles ★★★★★

Installed these in a steam valve application that keeps killing standard Buna-N rings, and so far the Viton is holding up perfectly at 300°F. The 90 durometer feels noticeably firmer than the 70A stuff I've tried, which gives me confidence they'll last. Just wish the package had a resealable bag for

Daniel ★★★★★

I needed something that could handle high heat near an engine compartment, and these o-rings haven't deformed or hardened after a few months of use. The 90 durometer feels solid and the pack of 150 gives great value for multiple repairs.

Scarlett ★★★★★

I was skeptical about getting the right fit for my hydraulic system, but these AS568-211 rings sealed perfectly with zero leaks. The 90 durometer material handles high temps like a champ.
