Hazel P. ★★★★★

I needed a durable seal for a high-temp application, and these o-rings handle up to 450°F perfectly without any sign of melting. The 0.139" cross-section fit snugly into my groove, and the 70 durometer gave just the right amount of flexibility.

Alexander V. ★★★★★

The bright red color makes them easy to spot during disassembly, and the 70 durometer silicone feels just right—firm enough to hold a seal but still flexible to stretch into place. I’ve used them in a hot water line up to 200°F and they haven’t softened or deformed after a month. A solid buy if you

Carter ★★★★★

These o-rings fit perfectly on my home brewing kettle's lid port, the 6.234" inner diameter was exactly as described. The bright red color makes them easy to spot during cleaning, and the silicone feels durable and pliable.
