Leo A. ★★★★★

Used a set replacing old gaskets on an outdoor water filter housing, and the -65°F rating gave me peace of mind through our last cold snap. The 70 durometer feels just right—firm enough to seal without needing a ton of force to install.

Benjamin ★★★★★

I needed a bulk pack of these for a high-temp pneumatic application and the 70 durometer EPDM handles the heat beautifully. They seat cleanly in the glands with no rolling, and the price per ring is unbeatable for the quantity.

Scarlett ★★★★★

These work perfectly in my steam valve rebuild kit, the 1.162" ID is exactly right. The 70 durometer feels just firm enough for a tight seal without being too hard to install.
