Brian ★★★★★

The metal-detectable feature is a huge plus for my food processing equipment—gives me peace of mind during maintenance. These 70-durometer Buna-N rings hold up well to the hydraulic fittings I’ve used them on. Fit perfectly and arrived quickly.

Steven U. ★★★★★

These are exactly the right size for my hydraulic fittings and the 70 durometer feels like the right firmness. I've only had them on for a few days, but the metal detectable part gives me some peace of mind for food-grade equipment.

Joseph ★★★★★

The metal detectable feature is a big plus for our food processing line—gives me peace of mind if one ever breaks mid-run. These 204 o-rings fit perfectly and the 70 durometer feels just right for the pressure we're dealing with.
