Customer Reviews (5.0 / 5 · 5 reviews)

Brian ★★★★★

The high-temp range on these is no joke—they held up perfectly on my smoker, which hits over 400°F. Also, the 70-durometer red silicone feels just firm enough without being brittle.

Edward ★★★★★

Replaced the old cracked seals on my pressure cooker with these and they seated perfectly right out of the bag. That red color makes them easy to spot during disassembly, and the 70 durometer feels firm but forgiving. Handling the -80°F rating gives me peace of mind for my freezer experiments.

Riley ★★★★★

Installed these in a high-temp pump application and they handled the heat without any visible wear after a month. The 70 durometer feels just right for a tight seal without being too stiff to work with.
