Customer Reviews (4.6 / 5 · 5 reviews)

Ava U. ★★★★★

I needed a reliable seal for a hot oil pump, and these HNBR rings handled the 250°F continuous exposure without any swelling or leaks. The 80 durometer gives them a nice firm feel during installation but they seat perfectly in the groove.

Scarlett ★★★★★

Used these in a high-temp hydraulic application where regular nitrile was failing. The HNBR material handles the heat well and hasn't hardened after a month of use. Fit was perfect on the first try.

Ava L. ★★★★★

Had to replace some old seals on a hydraulic press and these HNBR o-rings are handling the heat way better than the last ones I tried, which started leaking after a few months. The 80 durometer feels just right for the pressure we're running, and they slid right into the grooves without any fuss.
