Customer Reviews (4.6 / 5 · 5 reviews)

Joseph ★★★★★

The temperature range on these is what sold me — my application sees both freezing winters and hot summer days, and they hold up fine. The 11.484" inner diameter matched my groove perfectly, no stretching or wrestling to get them seated.

Chloe ★★★★★

Had to replace a worn seal on a hydraulic cylinder and these o-rings slid right into the groove with no fuss. The 70 durometer feels just firm enough that I'm confident they'll hold pressure fine under normal use.

Daniel Z. ★★★★★

I needed a large o-ring for a hydraulic cylinder repair and the 11.484-inch inner diameter fit perfectly. The 70 durometer rubber feels dense enough for a good seal but still flexible to install.
