Customer Reviews (4.6 / 5 · 5 reviews)

James ★★★★★

I needed a 70-durometer seal that could handle high heat, and these silicone rings feel robust in hand. They seated perfectly in my pressure cooker valve assembly with no distortion.

Violet ★★★★★

The red color makes them easy to spot when I'm digging through my spare parts bin, and the -80°F to +450°F range gives me confidence for hot applications. I've used about a dozen so far and they seat perfectly without any deformation.

Madison ★★★★★

I swapped these into a high-temp water seal on my lab rig, and they held up perfectly at 400°F with no softening. The 70 durometer feels just right—firm enough to seal tightly but not too stiff to compress.
