Customer Reviews (4.6 / 5 · 5 reviews)

Natalie ★★★★★

The 75-durometer hardness is spot on for my application—firm enough to hold a seal but they still compressed into the groove without a fight. This pack of 75 should last me a while, and the black Viton looks clean against the fittings.

Ella ★★★★★

Used these for a hydraulic fitting on a hot-oil system that peaks near 350°F, and they’ve held up without any hardening or leaks. The 75 durometer feels a touch firmer than the Buna-N ones I was using, but that’s exactly what you want at these temps.

Jacob E. ★★★★★

I needed a high-temp seal for a steam valve, and these Viton FKM o-rings with a 0.861" ID fit perfectly. They handle the 400°F max rating without any issues so far. The 75 durometer feels solid but still pliable enough to seat easily.
