Customer Reviews (4.8 / 5 · 5 reviews)

Daniel ★★★★★

Replaced some old gaskets in my hydraulic pump with these and so far absolutely zero leaks. The -40°F rating gives me peace of mind for winter use and the 80 durometer feels plenty firm.

Owen ★★★★★

These HNBR o-rings handled the heat without any softening, and the -40°F rating is a huge plus for our outdoor equipment. The 80 durometer feels firm but still seated easily into the groove.

Brian J. ★★★★★

The 0.21" cross-section on these HNBR o-rings gave a snug fit in my hydraulic fitting where standard nitrile was too loose, handling the -40°F rating for a freezer application without any cracking.
