Customer Reviews (5.0 / 5 · 5 reviews)

Ella ★★★★★

The brown color makes them easy to spot during assembly, which is a small thing but saves time. They slid on without any fuss and held up fine in our steam line, so the 400°F rating is clearly legit.

Nicholas ★★★★★

I needed a reliable seal for a high-temp hydraulic line, and these Viton FKM o-rings handled the 400°F service range without any issues. The 75 durometer feels just right for my application—firm but not overly stiff.

Riley S. ★★★★★

The brown color makes them easy to spot during assembly, which saved me time when checking the fit on a large flange. The 75 durometer hardness feels just right for a firm seal without being a bear to compress. These handled a 300°F hot oil line without any visible softening.
