Aurora ★★★★★

These o-rings fit my home fermentation vessel perfectly, and the heat rating up to 450°F gives me peace of mind for hot sanitizing cycles. The 70 durometer silicone feels just flexible enough for a tight seal without being too stiff.

Hazel Q. ★★★★★

The bright red color makes them easy to spot during assembly, which saved me time on a tricky install. They fit snugly on the 10.734" ID and handled a steam line at 300°F without any softening.

Michael ★★★★★

After trying several o-rings that couldn't handle my hot water recirculation loop, these silicone ones sealed perfectly and the red color makes them easy to spot during maintenance.
