Scarlett K. ★★★★★

I installed these on a hydraulic manifold and they seated perfectly without any binding. The metal-detectable feature gives me extra confidence for food processing equipment.

Kevin ★★★★★

The 70 durometer feels just right for a snug seal without being impossible to work into the groove. I appreciate that these are metal detectable for food processing applications - gives me peace of mind during maintenance.

Samuel ★★★★★

The 5.359" inner diameter fit my flange perfectly without any wrestling, and the 70 durometer feels firm enough to hold pressure without being a pain to seat. The metal-detectable aspect gives me real peace of mind since these are going into a food processing line.
