David ★★★★★

The -15°F to +400°F range is exactly what I needed for a hot oil line that kept cooking my old seals. These Viton rings slipped in easy and have held their shape through a dozen heat cycles so far.

Leo A. ★★★★★

Replaced the old Buna-N seals in my air compressor and these Viton rings fit the groove perfectly, no trimming needed. The 75 durometer feels firm but not brittle, and the -15°F to +400°F range covers everything I'll ever throw at it.

Kevin N. ★★★★★

Been using these in a hydraulic cylinder that sees 300°F+ oil, and they haven't softened or leaked after two weeks of cycling. The 0.859" ID fit perfectly on the shaft, and the kit gives you enough spares for multiple projects.
