Watts 0780333 Copper Float

When you are dealing with critical water level regulation in industrial or agricultural systems, the Watts 0780333 (also known as the Watts 780333) is the industry standard for heavy duty float valves. This 8 inch copper float ball is engineered from high-grade copper with firmly bonded overlapping joints to ensure structural integrity in non-potable applications. Designed for a 3/8-16 female thread connection, this C8 float ball provides the buoyancy required for high-capacity cooling tower water make up, large livestock watering tanks, and commercial refrigeration units. With a maximum working temperature of 200°F and a specific gravity of 0.13, this float ensures precise liquid level control in open tank environments. Whether you are performing a float valve replacement or setting up a new HVAC water level sensor assembly, this 8" sphere delivers the mechanical lift needed for consistent valve actuation and overflow prevention.

Key Benefits

• Industrial-Grade Construction: Manufactured from high-grade copper with lead-free solder for open tank water applications.
• Universal Compatibility: The 3/8-16 inch internal thread fits most standard professional float stems and valve assemblies.
• High Temperature Resistance: Sustains performance in HVAC make up water and heat transfer units up to 200 degrees Fahrenheit.
• Exceptional Buoyancy: The 8-inch diameter (C8 series) provides high displacement for heavy mechanical valve shut-offs.

Common Questions
