Christopher ★★★★★

The 75 durometer hardness feels just right for my application, and the Viton material handled repeated exposure to hot oil without any swelling. These fit snugly on the groove and I’ve already used a few from the pack with no leaks.

Madison Q. ★★★★★

I needed an odd size for a high-temp plumbing fix, and these Viton FKM rings handle the heat without any issue. The 0.139" cross-section was a perfect fit for the groove, and the package of 26 gave me plenty of spares.

Leo ★★★★★

Used these in a high-temp compressor rebuild and they seated perfectly with no leaks. The 75 durometer feels exactly right for the pressure range I'm running, and they handle the heat without getting brittle.
