Hannah C. ★★★★★

I was worried about finding the right size for my hydraulic cylinder, but the 6.109" ID fit perfectly on the first try. The 70 durometer feels firm yet flexible, and the package of 12 gives me spares for the next few maintenance jobs.

Brian ★★★★★

The metal-detectable feature gives me peace of mind in our food processing line, and the 70 durometer feels just right for the seal. I measured one and the 6.109" ID was spot on, so these are perfect for my application.

Nicholas I. ★★★★★

Finally found o-rings with the exact 6.109" ID I needed for a hydraulic cylinder rebuild, and the 70 durometer feels just right for the job. The metal-detectable feature is a nice safety bonus for our food-grade equipment.
