Repair or replacement of commercial shower components, rather than replacement of the entire unit, saves money and resources. Made for Zurn Temp-Gard III tub valves, the TPK7300-SS tract pack includes a 4-port valve only with tub plug, service stops, and 1/2-inch female NPT threaded connections. Temp-Gard pressure-balancing valves maintain a consistent water temperature and feature a unique ceramic control cartridge for lasting performance. 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.
