Customer Reviews (4.2 / 5 · 5 reviews)

Thomas ★★★★★

Installed these on a high-temp air compressor head where standard Buna-N kept failing. The Viton seals held up through a full 400°F bake cycle without any visible degradation.

Carter X. ★★★★★

I needed a high-temp seal for my compressor rebuild, and these Viton rings handled the 350°F operating temperature without any issue. The 75 durometer hardness gave them just enough flexibility to seat properly in the groove, yet they feel firm and durable.

Ruby ★★★★☆

The 6.234" ID fit perfectly on my hydraulic cylinder flange, and the Viton material handles the occasional hot oil splashes without swelling. My only nitpick is the package count—14 rings is an odd number when most jobs come in pairs.
