Jason ★★★★★

The high temperature rating on these red o-rings gives me peace of mind for my brewing equipment, and the 70 durometer feels just right for a snug, leak-free seal.

Ryan X. ★★★★★

Replaced the worn out seals in my hot water manifold with these and the -80°F to +450°F range gives me peace of mind for the steam side. The red color makes them easy to spot during assembly, and the 70 durometer holds shape nicely under compression.

Richard ★★★★★

The 70 durometer feels just right for my application—firm enough to seal properly but still easy to install. I've had them on a hot water line for three weeks now and they haven't softened or deformed, which says a lot given the 450°F rating. The red color makes them easy to spot during inspection t
