David X. ★★★★★

The temperature range on these is exactly what I needed for a high-heat application—they’ve held up fine at 400°F without any softening. The 70 durometer feels firm but still seals nicely, and the metal-detectable aspect is a solid safety bonus for food equipment.

Carter ★★★★★

The metal-detectable feature gives me peace of mind in our food processing line, and these 70 durometer o-rings seal perfectly on our mixers. They handle the heat cycling from -80°F without any cracking, a huge upgrade from what we used before.

Madison F. ★★★★★

Finally found o-rings that hold up in my autoclave cycles—these silicone ones hit the -80°F to +450°F range I needed. The 70 durometer feels just right for a snug seal without being impossible to install.
