Michael ★★★★★

The 300°F rating is the reason I picked these for a hot oil line, and so far they’ve held up perfectly without any hardening. The 80 durometer feels firm but still seats easily, and the 2.109" ID matched my groove exactly. Package of 30 means I’ve got spares for the next job, which I’ll definitely n

Madison ★★★★★

Replaced the old Buna-N seals on my hydraulic cylinder with these HNBR o-rings and they’ve held up perfectly through several hot cycles. The 80 durometer feels just firm enough without being brittle.

Hannah ★★★★★

Installed these on a high-temp air compressor manifold, and the HNBR material handled the heat without any issues. The 80 durometer hardness made them firm enough to seal properly but easy to slide into the groove.
