Watts 0780330 Copper Float

For industrial mechanical systems requiring precise fluid level management, the Watts 0780330 Copper Float is a heavy-duty solution designed for high-performance float valve assemblies. Also identified as model 780330, this 6-inch copper float is engineered from high-grade copper with firmly bonded overlapping joints to ensure structural integrity in non-potable cooling tower water systems and HVAC make-up water tanks. With a 1/4-20 internal female thread connection, it integrates seamlessly with standard heavy duty float valves used in refrigeration units and cooling tower basins. This unit is built to withstand operating environments up to 200°F (93°C), making it a reliable choice for mechanical contractors maintaining commercial heat transfer units or industrial pressure washers. Its buoyance (specific gravity 0.13) provides the consistent upward force needed to seal valves effectively against moderate supply pressures, minimizing water waste and preventing basin overflows in open-tank liquid level control applications.

• High-grade copper construction with reinforced overlapping joints for durability in high-cycle mechanical float valve applications.
• Standard 1/4-20 female thread for universal compatibility with most industrial float valve stems.
• High-temperature resilience, rated for fluid temperatures up to 200 degrees F.
• Robust 6-inch diameter provides the necessary displacement for reliable liquid level control in large reservoirs.
• Direct replacement for Watts 0780330, ensuring zero-mod installation for existing HVAC float assemblies.

Is the Watts 0780330 float suitable for potable water?
No, this copper float is designed specifically for non-potable water applications and does not meet low-lead requirements for human consumption systems.

What is the thread size for this copper float?
This model features a 1/4-20 female connection. Please verify your stem size, as some high-capacity industrial valves may require an adapter or a 3/8-16 thread version.

What is the difference between Watts 0780330 and 780330?
These part numbers are identical. The 0780330 is the full manufacturer SKU for the C6 6-inch copper float.
