Thomas G. ★★★★★

Installed these on our hot water filtration system and they sealed perfectly with no leaks. The red silicone is easy to spot during assembly and maintains flexibility even in near-boiling temperatures.

Ava M. ★★★★★

The 70 durometer feels just right for getting a snug seal without being a struggle to install. These 0.139" cross-section rings fit perfectly on my brewing kettle's lid, and I love that they're FDA compliant for food contact.

Aurora J. ★★★★★

I needed a reliable seal for a high-temp water system, and these rings fit perfectly at 0.859" ID without any binding. The red color makes them easy to spot during assembly, too.
