Evelyn I. ★★★★★

These o-rings handled the 350°F heat cycling from my autoclave perfectly with zero softening. The brown color made them easy to spot against the metal parts during assembly, which saved me some hassle.

Joseph Q. ★★★★★

These Viton o-rings fit perfectly on my old hydraulic cylinder, and the 0.139" cross-section gave just the right squeeze for a leak-free seal. I'm impressed they handle the high heat around my pump without any hardening or cracking.

Claire ★★★★★

The -15°F to +400°F range is exactly why I grabbed these for my steam line, and they’ve held up through several cycles without any hardening. Brown color makes them easy to spot during inspection too. These fit my 8.5-inch bore perfectly.
