Andrew I. ★★★★★

The metal-detectable feature gives me peace of mind in our food processing line, and the 70 durometer feels just right for sealing. These 211 o-rings fit my pneumatic valves precisely and arrived in a bulk pack that'll last a while.

Thomas V. ★★★★★

These fit perfectly in my hydraulic cylinder, and the metal detectable feature gives me peace of mind for food processing. The 70 durometer feels just right for a tight seal without being too stiff.

John ★★★★★

Finally, an o-ring that stays pliable even in the cold; these held a perfect seal after a night at -20°F. The metal-detectable feature is a nice safety bonus for our food equipment.
