Customer Reviews (4.8 / 5 · 5 reviews)

Chloe X. ★★★★★

Had a leaking hydraulic cylinder that needed exactly these 1.359" ID rings, and the 70 durometer feels quality in hand. They sealed perfectly on the first try, and the pack of 500 should last me a good while.

Thomas ★★★★★

The 0.139" cross-section is beefier than the standard 220s I've used before, so these seal tighter in my hydraulic fittings. I've already replaced about a dozen leaky connections and haven't had a single one weep since. My only regret is not switching to this size sooner.

Amelia V. ★★★★★

Bought a 500-pack because I was tired of running out mid-project, and these hit the spec right—the 70 durometer feels firm but they seat easily in my fittings. The -40°F rating is a nice safety margin for my garage setup, so I can stop worrying about cold-weather leaks.
