Customer Reviews (4.4 / 5 · 5 reviews)

Abigail Z. ★★★★★

These fit perfectly in my hydraulic cylinder's gland groove. The 400°F rating gives me peace of mind since my system runs hot.

James T. ★★★★★

The 70 durometer hardness feels just right for my application, and the 4.359" inner diameter seated perfectly without any forcing. I've had these in a hot oil environment for weeks now and they haven't softened or deformed one bit, which is exactly what I needed.

Scarlett B. ★★★★★

I replaced worn-out rings in a hydraulic clamp with these, and the 70 durometer feels just right for the seal. They slid into the groove easily and the Viton should handle the heat without issue.
