Abigail D. ★★★★★

I've been using these to seal a high-temp flange on a small boiler, and they hold up perfectly at 400°F without any degradation. The 1.296" inner diameter fits snugly without being impossible to seat. Exactly what I needed for a demanding application.

Scarlett I. ★★★★★

The 75 durometer feels firm but flexible enough to get a snug fit without distorting. I’ve been using them in a high-temp application around 350°F, and they hold up better than the standard Buna-Ns I tried before. Perfect match for my AS568-219 groove specs.

Penelope ★★★★★

I needed seals that could handle high heat, and these Viton FKM o-rings’ 400°F rating gave me confidence for my compressor rebuild. The 75 durometer feels firm but pliable enough to seat perfectly in the groove.
