Lily V. ★★★★★

Needed these for a high-temp hydraulic repair and the 400°F rating gave me confidence they’d hold up. Installed easily with a snug fit and no leaks after a full day at operating temp.

Steven ★★★★★

The 75 durometer hardness feels just right for my application, and they seated into the groove without any twisting or rolling. I've got spares for the next rebuild since they come in a 16-pack, which is nice. The temperature range up to 400°F gives me confidence they'll hold up under heat.

Thomas O. ★★★★★

Finally got around to swapping out the old seals in my hydraulic press, and these Viton FKM rings fit perfectly at 5.234" ID. They handle the 350°F operating temp without any softening, which is exactly what I needed.
