Isabella V. ★★★★★

The 0.21" cross-section made these an exact fit for my industrial autoclave door. I was pleased to find them so supple yet durable at high temperatures, handling the 400°F steam cycles without any issue.

Eli ★★★★★

Used these to replace the aging seals on a commercial autoclave door, and the 70 durometer silicone held up perfectly during the first high-temp cycle. The -80°F to +450°F service range gives me confidence they’ll last through daily sterilization runs.

Emma S. ★★★★★

Swapped out a worn steam table gasket with these and the fit was perfect—the 70 durometer red silicone sealed tight on the first try. They handled a 400°F oven cycle without any softening or leaks.
