Andrew ★★★★★

The 0.21” cross-section on these o-rings made for a perfect, snug fit where others had been too thin. I’ve been using them in a high-heat pump application and they haven’t shown any wear after two weeks of constant use.

Ryan S. ★★★★★

Finally found o-rings that can handle the heat near my furnace without melting. The 75 durometer feels firm and they seated perfectly in the grooves.

Emma H. ★★★★★

I needed replacements for a high-temp hydraulic system and these rated up to 400°F fit the bill. The 75 durometer feels firm yet pliable, and they seated easily without any twisting. These should definitely hold up under the heat.
