Customer Reviews (4.6 / 5 · 5 reviews)

Miles ★★★★★

These fit perfectly on my hydraulic cylinder rebuild and handled the 200°F fluid without any issues. The 70 durometer feels nice and firm for a reliable seal.

Owen ★★★★★

Installed these on a sticky valve assembly last night and they seated perfectly without any pinching. The 70 durometer stiffness felt just right for a snug seal under moderate pressure.

William ★★★★★

I've been using these for a hydraulic application and the 70 durometer feels firm but not brittle. They handled the 200°F fluid in my test run without any swelling or leaks. Exactly what I needed for a quick rebuild.
