حلقات O من السيليكون | 0.103" CS X 2.174" ID | AS568-139 | داش 139 | قابلة للكشف المعدني | صلابة 70 (20/عبوة)

I needed a reliable seal for a food processing machine and these o-rings work perfectly because they're metal detectable. The 70 durometer feels just right—not too stiff, not too soft—and they slid into the groove easily.

I bought these for a high-temp sealing application and the 70 durometer silicone handles the heat exactly as advertised. The metal-detectable feature gives me peace of mind in our food processing line, and the 20-pack is a solid value.

The metal-detectable feature is a huge plus for our food plant's safety checks, and the 70 durometer feels just right for a snug seal. These fit perfectly in the 2.174" ID groove on our mixing vat lids.
