Joshua E. ★★★★★

I’m working on a food processing line, so having o-rings that are metal detectable is a big safety plus. The 70 durometer feels a little firmer than the standard ones I’ve used before, which should help with sealing under higher temps up to 250°F.

Lily ★★★★★

I needed a size I couldn't find locally and these o-rings are a perfect fit for my hydraulic repair job. The 70 durometer feels just right and the metal-detectable feature is a safety plus when working around food equipment.

Alexander ★★★★★

The metal-detectable feature gives me peace of mind in a food processing line where a broken o-ring could be a nightmare. They slid right into the grooves of our hydraulic cylinder with no struggle, and the 70 durometer feels just right for the medium-pressure seal I needed.
