Samuel ★★★★★

These o-rings fit the hydraulic fitting I was repairing perfectly, with a nice snug seal that doesn't leak. The 70 durometer felt just right for a high-pressure application, not too stiff. Definitely a solid value for a bulk pack that'll last through multiple projects.

Penelope ★★★★★

I was worried about finding the right fit for my hydraulic cylinder, but the 2.111" ID on these seals was dead-on. The 70 durometer gives them a nice, firm feel without being too stiff.

Hannah ★★★★★

The 0.103" cross-section makes these O-rings fit perfectly into the groove on my hydraulic cylinder, and the buna-n material feels durable even at higher pressures. I used about half the pack for various seals with no leaks.
