Julian U. ★★★★★

Installed a couple hundred of these on a pneumatic manifold rebuild, and the 70 durometer hardness gave just enough squeeze without being a pain to seat. Much better than the cheaper mixed bags I've been using.

Lily U. ★★★★★

I needed a large batch of these for a hydraulic repair job, and the 700-count pack means I won't be running out anytime soon. The 70 durometer rubber feels just right for the pressure range I'm working with.

David B. ★★★★★

These o-rings fit the air cylinder ports on my mill perfectly. The cross-section is exactly 0.139" as listed, and they feel durable. They sealed on the first try with no leaks.
