Manufactured from Hydrogenated Nitrile Butadiene Rubber (HNBR), this black o-ring is a genuine spare part designed for use with the Danfoss / Eaton Ez Clip fitting system. HNBR offers strong resistance to hydraulic fluids, heat, and mechanical wear, making it well suited for demanding hydraulic service environments where seal integrity is critical.
Available in a variety of sizes to accommodate different fitting configurations, this o-ring is sourced directly from Eaton Aeroquip and is intended as a replacement component within compatible Ez Clip assemblies. Refer to Eaton's fluid compatibility documentation to confirm suitability for specific fluid media before installation.

Hydrogenated Nitrile Butadiene Rubber, or HNBR, is what these are made from. That material handles heat, oil, and general hydraulic fluid exposure better than standard nitrile in most cases. It's a step up in durability and is commonly used in demanding hydraulic fitting applications.
