Samuel ★★★★★

Needed to replace some seals in a high-temp application, and these Viton o-rings handled the 350°F steam line without any issue. The 0.139" cross-section made them easy to seat in the groove.

Miles P. ★★★★★

The 75 durometer brown ones fit perfectly in my application and I’m glad I got a 150 pack for spares. Temperature range down to -15°F was exactly what I needed for a cold-weather seal. These o-rings feel much more durable than the standard ones I’ve used before.

Mia F. ★★★★★

I needed o-rings that could handle high heat near my kiln, and these Viton ones are rated up to 400°F, which is exactly what I was hoping for. The 75 durometer feels firm but not brittle, and the brown color makes them easy to spot against dark metal parts.
