Julian Z. ★★★★★

The 80 durometer feels plenty stiff for my application, and the -40°F rating gives me confidence they'll hold up outdoors this winter. Pack of 25 is a solid value for a spare-parts bin.

Thomas P. ★★★★★

These fit the AS568-154 groove perfectly and the 80 durometer feels just right for my hydraulic application. I’m relieved they’re rated for the higher heat range, as my previous set failed in similar conditions.

Thomas ★★★★★

I needed o-rings that could handle high heat near my engine’s exhaust, and these HNBR ones took the 300°F rating seriously—no cracking after a week of use. The 80 durometer feels just right for a snug seal without being too stiff to install.
