The Watts 0780328, commonly cross-referenced as the P8 Plastic Float or 780328, is an 8-inch heavy-duty component engineered for industrial fluid level management. Constructed from high-density, injection-molded polyethylene, this float is purpose-built to withstand aggressive environments, remaining completely non-electrolytic and highly resistant to corrosion from salt and caustic fluids. Technicians frequently deploy the Watts P-8 float in cooling towers, refrigeration units, and high-capacity pressure washer tanks where chemical resilience is non-negotiable. Its robust 3/8-16 inch female thread ensures a secure connection to standard float valve stems, maintaining a maximum working temperature of 140°F. Whether used in livestock watering tanks or commercial heat transfer units, the 0780328 provides the necessary buoyancy and responsiveness to trigger valve closure precisely, preventing overflow and ensuring consistent system pressure. This polyethylene float ball also features UV-resistant properties to prevent sunlight deterioration in outdoor agricultural or irrigation applications. Corrosion Resistance: Injection-molded polyethylene build is unaffected by caustic fluids and salt, ideal for harsh chemical processing. Universal Compatibility: Standard 3/8-16 female thread fits a wide range of industrial float valve assemblies. Thermal Stability: Rated for fluid temperatures up to 140 degrees Fahrenheit, suitable for various HVACR make-up water systems. Environmental Durability: UV-resistant material prevents cracking and degradation when installed in exposed cooling towers or tanks. Common Questions What is the thread size for the Watts 0780328? This model features an internal 3/8-16 inch female thread connection, designed for heavy-duty brass or stainless steel stems. Can this float be used in potable water systems? While the Watts P8 is lead-free compliant, it is primarily intended for industrial, agricultural, and HVACR applications like refrigeration units and cooling towers rather than direct human consumption lines. Is the P8 float resistant to chemical breakdown? Yes, the polyethylene construction is engineered specifically to resist caustic fluids and non-electrolytic action, making it superior to metal floats in corrosive environments.
