Jason M. ★★★★★

The red color made it easy to spot during assembly, and the 70 durometer feels firm but flexible enough to seat perfectly in the groove. This 11.984" ID silicone ring handled my hot water filtration setup without any issues straight out of the package.

Thomas Q. ★★★★★

I needed a large-diameter o-ring that could handle high heat from my home canning setup, and these silicone ones fit the bill perfectly with their 450°F rating. The 11.984" inner diameter was spot on for my pressure canner lid, and the red color makes them easy to spot in the drawer.

Andrew B. ★★★★★

These O-rings fit perfectly on my large pressure cooker lid, and the 70 durometer silicone feels much more durable than the old rubber ones I replaced. The 450°F heat rating gives me peace of mind for high-temp canning.
