Benjamin A. ★★★★★

I needed o-rings that could handle a steam cleaning setup that gets well past boiling, and these Viton ones fit the bill perfectly with their 400°F rating. The 75 durometer feels nice and firm but sealed up my flange without needing to crank it down.

William ★★★★★

The higher temperature rating is exactly what I needed for my hydraulic application—these Viton rings hold up well where standard rubber failed. The brown color makes them easy to spot during assembly.

Natalie T. ★★★★★

The 0.139" cross-section sealed my pump housing on the first try with no leaks. I was surprised how pliable these still felt even after sitting in my cold garage for a week.
