Repair or replacement of commercial shower components, rather than replacement of the entire unit, saves money and resources. Zurn’s extension kit (Part no. RK7000-50EXT) is made to be used with the Temp-Gard® I shower valve stem repair kit (RK7000-50) to provide a 1 1/4-inch extension. Temp-Gard® pressure-balancing valves maintain a consistent water temperature. Zurn replacement parts are manufactured to provide long-term durability for commercial showering applications. When you need a replacement part for repair or maintenance of a tub or shower valve, trust Zurn for genuine, reliable parts.
