Zoe ★★★★★

I needed a reliable seal for a high-heat application and these Viton o-rings handle the 400°F rating perfectly. The 75 durometer feels firm yet flexible enough to seat snugly into the groove without distortion.

Timothy A. ★★★★★

The high-temperature rating is exactly what I needed for a steam line repair, and these 75-durometer rings sealed perfectly on the first try. They fit the AS568-259 groove without any struggle or distortion.

Joseph ★★★★★

Finally found o-rings that handle the high-temp grease in my oven's door seal without degrading. The 75 durometer feels just right — firm enough to hold pressure but not brittle.
