Customer Reviews (4.6 / 5 · 5 reviews)

Olivia M. ★★★★★

The inner diameter is spot on for the hydraulic cylinder I was rebuilding, and the 70 durometer gives them a firm but not brittle feel. These are the third batch I've ordered, and they seal perfectly every time.

Emily U. ★★★★★

The 70 durometer was exactly right for sealing a new hydraulic reservoir cap I machined. Handled the 200°F test cycle without any issue, and the pack of 300 gives me plenty of spares for future projects.

George ★★★★★

Finally found a reliable replacement for my hydraulic press seals. These o-rings fit perfectly and the 70 durometer feels appropriate for standard industrial use.
