Stella ★★★★★

I needed a Viton FKM seal for a high-temperature application near a kiln, and the 400°F rating on these 323 dash rings gives me real peace of mind. The brown color also makes them easy to spot against metal parts during maintenance.

Robert R. ★★★★★

Finally, a Viton o-ring that doesn't crack after a few months near my hot air system. The 75 durometer feels firm but still seats snugly in the groove, and the brown color makes them easy to spot against the metal.

Kevin ★★★★☆

The 75 durometer hardness is spot on for my application, and these feel much more durable than the nitrile rings I was using before. The brown color makes them easy to spot during assembly, which is a nice bonus. Just wish they came in a smaller pack since 40 is more than I'll use this year.
