Customer Reviews (4.8 / 5 · 5 reviews)

Richard ★★★★★

I needed these for a high-temp application, and the -80°F to +450°F range on these FDA compliant rings gives me peace of mind. They seated perfectly on first try, no leaks.

James ★★★★★

I needed an o-ring for a high-temp industrial gasket, and the red silicone handled 400°F without any softening. The 70 durometer feels pliable yet stays rigid under compression, a solid upgrade from my old rubber ones.

Andrew I. ★★★★★

These fit perfectly into our steam table lid, and the red silicone makes them easy to spot if one falls. The 70 durometer feels firm but seals nicely against the hot pans.
