George Z. ★★★★★

Finally found EPDM o-rings that handle both hot water and colder outdoor temps in my brewing setup without getting brittle. The 70 durometer is firm enough to seal well but still easy to install on the flange.

Michael B. ★★★★★

I've been using these for sealing a small pneumatic cylinder, and the 70 durometer feels just right for a snug fit without being too hard. The temperature range from -65°F to +300°F gives me confidence they'll hold up in both cold and hot conditions.

Emily H. ★★★★★

These fit my hydraulic fittings perfectly—the 70 durometer rubber feels substantial and durable. I'm glad I grabbed the 110-pack since I'll be using them for several different projects around the shop.
