Elizabeth ★★★★★

Installed these in a hot-water manifold that hits around 200°F and they haven't leaked a drop after two weeks of daily use. The 3.109" ID fits my groove perfectly, and the 70 durometer is firm enough to seat well without being a struggle to stretch into place.

Daniel ★★★★★

I was worried about the cross-section being precise enough for a stubborn pneumatic cylinder, but these 70-durometer rings seated perfectly on the first try. They've held pressure without any leaks through several heat cycles, so the EPDM material clearly handles the temperature swings as advertised

Grace H. ★★★★★

These seals fit perfectly into my hydraulic cylinder's gland, and the EPDM material handles the heat from the hot water recirc loop without any issues. The 70 durometer feels pliable yet durable, and the pack of 60 should last me years.
