Customer Reviews (4.4 / 5 · 5 reviews)

Miles P. ★★★★★

The wide 0.139" cross-section feels much more durable than the skinny o-rings I've used before, and at 80 durometer they're definitely stiff enough for a high-pressure seal. Took these for a hydraulic repair in my shop and they haven't leaked a drop so far, even with the fluid running warm.

Owen G. ★★★★★

The -40°F rating is the reason I grabbed these for a cold-weather hydraulic setup, and the 80 durometer holds its seal nicely under pressure. The 5.734" ID was exactly on spec, which saved me from having to send a set back.

Mia ★★★★★

These o-rings fit perfectly into a hydraulic cylinder I was rebuilding, and the 80 durometer feels nice and firm. The -40°F to 300°F range gives me confidence it'll hold up in my heated shop.
