حلقات O من السيليكون 0.139" CS × 0.859" ID | AS568-212 | داش 212 | قابلة للكشف المعدني | صلابة 70 (28/عبوة)

The temperature rating is what sold me—my last batch of o-rings cracked in the cold, but these are rated down to -80°F and I've had zero issues since installing them. The 70 durometer stiffness feels just right for my application too.

The metal detectable feature gives me peace of mind in our food processing setup, and the high temp rating is exactly what we needed. I’ve bought these multiple times now and they hold up perfectly under steam.

Finally, O-rings that don't degrade after a few months in my hot oil setup. The -80°F to +450°F range gives me real peace of mind, and the metal-detectable feature is a nice safety bonus for food equipment. They seated snugly with no stretching issues.
