Julian ★★★★★

The 60 durometer is just right for my application—soft enough to seat easily but firm enough to hold pressure. These white Viton rings cleaned up nicely with no residue.

Jacob L. ★★★★★

I needed FDA-compliant seals for a food processing line, and these white Viton rings fit perfectly. They handle the hot caustic wash cycles without swelling.

Avery ★★★★★

I grabbed these for a high-temp steam valve rebuild and the 60 durometer is just right—still flexible but holds its seal perfectly. They fit the 3.359" groove without any wrestling, which was a relief.
