Ryan P. ★★★★★

I needed a 4.734" inner diameter o-ring for a high-heat food processing machine, and these silicone ones fit perfectly and handled 400°F without any issues. The 70 durometer feels just right for a tight seal without being too stiff to install.

Leo O. ★★★★★

The red color makes them easy to spot on the assembly line, and the 70 durometer feels just right for my food-grade gasket replacement. Worked perfectly on my first test run with hot water.

Claire D. ★★★★★

These are holding up perfectly on my high-temp pressure washer setup, the 70 durometer silicone feels just right. The red color makes them easy to spot during maintenance, and so far no signs of degradation after several hot cycles.
