Richard ★★★★★

The 1.037" inner diameter is a perfect fit for my hydraulic cylinder, and the 80 durometer feels quality. These arrived fast and work great sealing in some pretty hot hydraulic fluid.

Olivia L. ★★★★★

The 80 durometer rating on these HNBR o-rings feels just right for my hydraulic application, sealing perfectly without being too stiff. I installed a few and they seated snugly in the groove, so I'm confident they'll handle the -40°F to +300°F range as promised.

Owen K. ★★★★★

I’ve been shopping for a replacement set of these for my hydraulic fittings, and the fit is spot-on at 1.037" ID. The 80 durometer hardness feels firm enough for the pressure I’m running, and the package of 30 is plenty for a few rebuilds.
