Industrial 052-0010-HC Grounding Ring

The 052-0010-HC Grounding Ring is a flange-mounted electrical bonding device that provides electrical continuity and grounding across flanged connections in industrial piping. Sized for 4 in nominal pipe size and compatible with ANSI/ASME B16.5 Class 150 flanges, it installs between flange faces to resist static buildup and maintain safe, reliable grounding in oil and gas, chemical processing, water treatment, and power-generation facilities. The part is available in stainless steel or carbon steel configurations (dependent on the installation) to deliver industrial-grade corrosion resistance, and is suitable for both indoor and outdoor industrial service. Manufactured with MPN 052-0010-HC, model/reference 320-1, the grounding ring supports a range of applications from repair and retrofit to replacement of grounding components, ensuring continued electrical bonding across flanged connections and enhancing personnel safety. Common replacements in the field include Metra-flex 4 in Class 150 grounding rings, Garlock 4" Class 150 grounding rings, and Flexi-craft 4" ANSI 150 grounding rings.
