Brian C. ★★★★★

These are a perfect fit for my hydraulic press—the 9.975" inner diameter slid right over the shaft. I've been running them at 400°F for a few days now and they haven't hardened at all.

Timothy ★★★★★

The high-temp range is exactly what I needed for my oven door gasket—these seals handle 450°F without any issues. They fit snugly and the red color makes them easy to spot during maintenance.

Joshua H. ★★★★★

I was worried these would be too stiff for my application, but the 70 durometer silicone is actually quite flexible and easy to work with. They fit perfectly on the 10-inch lid, and the red color makes them easy to spot during maintenance.
