Elizabeth R. ★★★★★

Had to replace a seal in a food processing line and these FDA-compliant rings fit the groove perfectly. The 70 durometer feels right for the application, stiff enough to hold pressure but not brittle.

Robert Y. ★★★★★

The cross-section on these is spot-on for my application, and the 70 durometer feels solid without being brittle. I appreciate that they hold up to the -40°F to +250°F range, since my setup sees both extremes. A full bag of 250 for the price is hard to beat.

Riley ★★★★★

Needed a reliable seal for a food-grade application and these o-rings fit the bill perfectly, the FDA compliance gave me peace of mind. They slide into place easily and the 70 durometer feels robust without being too stiff.
