Customer Reviews (4.8 / 5 · 5 reviews)

Penelope ★★★★★

I needed a high-temp seal for a hydraulic fitting near a heat source, and these Viton FKM o-rings fit perfectly thanks to their 400°F rating. The 50-pack gives me plenty of spares for future repairs.

Riley ★★★★★

The 75 durometer hardness is spot on for my application—firm enough to hold a seal but still squeezes into the groove easily. I've had these on a hot oil system running near 300°F for a month now and zero leaks so far. Exactly what I needed for the AS568-220 spec.

Richard N. ★★★★★

I work with high-temp steam lines, and these Viton o-rings handle the 300°F+ heat without any degradation. The 75 durometer feels firm but still seals nicely against the metal flanges.
