Alexander ★★★★★

Needed a seal for a hot oil application and these brown Viton rings handled the 400°F max without any softening. The 0.139-inch cross-section fit my groove perfectly.

Ruby ★★★★★

The high-temp rating was exactly what I needed for a sealing application near a heat source, and these Viton o-rings fit perfectly without any distortion. I've already ordered a second pack.

Madison ★★★★★

These are replacing some standard rubber ones that kept failing in a hot application. The 75 durometer feels firm yet still seats properly, and the -15°F to +400°F range gives me real peace of mind that they'll last.
