For veteran HVACR technicians and facility managers, the Watts 0780356 Plastic Float (also recognized by contractors as the Watts P8-7) is a critical component for maintaining precise fluid levels in high-demand environments. This heavy-duty 8-inch plastic float is engineered from high-density polyethylene (HDPE), utilizing a specialized injection-molded construction that ensures the unit remains non-electrolytic. This is vital when the system is exposed to salts, caustic fluids, or corrosive chemicals common in industrial cooling towers and livestock watering stations. The 5/16-18 female thread connection provides a secure, vibration-resistant fit to standard float rods, ensuring the assembly provides consistent buoyancy even in turbulent makeup water tanks. Designed to withstand a maximum operating temperature of 140 degrees Fahrenheit, the 0780356 offers superior resistance to UV degradation and chemical wear. Whether you are servicing a pressure washer reservoir or a refrigeration unit, this industrial float ball delivers the rugged performance required to prevent system overflow and dry-run conditions. Key Benefits Extreme Corrosion Resistance: All injection-molded polyethylene construction is unaffected by salts and caustic cleaning agents. UV & Sunlight Stability: Specifically formulated to resist sunlight deterioration in outdoor agricultural or cooling tower installations. Universal Compatibility: Features a standard 5/16-18 inch female thread for seamless integration with existing float valve stems. High Buoyancy Rating: The 8-inch diameter provides the necessary lift to actuate heavy-duty float valves in high-volume fluid management systems. Common Questions Are the Watts 0780356 and P8-7 interchangeable? Yes, the 0780356 and P8-7 are identical parts. We recommend ordering by the Watts 10-digit ordering code (0780356) to ensure exact specification matching for your replacement hardware. Can this float be used in high-temperature boiler applications? This HDPE float is rated for a maximum temperature of 140°F (60°C). For steam or high-temperature boiler feed systems exceeding this threshold, a stainless steel or copper float should be utilized instead. What type of media is this float compatible with? This unit is ideal for water, light acids, salts, and various caustic fluids. Its non-electrolytic properties make it superior to metal floats in applications where electrolysis or galvanic corrosion is a concern.
