SKU CH-HZZ4-79YWR

Copper float ball with internal 3/8-16 thread, 0.3 oz weight and 200 °F liquid rating for automatic watering systems

  • Copper construction resists corrosion in water systems
  • 8 inch diameter provides reliable buoyancy control
  • 3/8-16 thread fits standard plumbing connections
  • Withstands liquids up to 200 degrees Fahrenheit
  • Low specific gravity of 0.129 ensures proper float operation

Copper Float Ball for Automatic Watering

The Watts C8FLT is a copper float ball designed for use with automatic watering kits, stems and nozzle assemblies. Its 8 inch diameter and 3/8-16 internal thread allow direct connection to compatible valve mechanisms in agricultural or industrial tank systems.

Thermal Limits and Buoyancy

The float operates in liquids up to 200 degrees Fahrenheit, making it suitable for heated water circuits. A specific gravity of .129 and a weight of .3 ounces provide the buoyancy required to actuate the connected valve reliably across the temperature range.

Kit Integration

The component is sold as a single float ball without stems, nozzles or valve bodies. Installers must supply the matching automatic watering kit hardware to complete the level-control assembly.

Questions about this item

How is the 3/8-16 internal connection fitted to the stem or nozzle assembly?

Thread the copper float ball onto the 3/8-16 stem or nozzle assembly by hand until snug, then tighten gently with a wrench on the float flats; the step often missed is confirming the arm swings freely through its full travel without binding.

What maintenance or replacement will the 8 in copper float ball need later?

Inspect the 0.129 specific-gravity copper float periodically for dents, corrosion or water ingress that would change its buoyancy, and replace the ball if it no longer rides at the correct level.

What limit appears first when the float operates continuously at the 200 Degrees F maximum liquid temperature?

Sustained use at the 200 Degrees F rating can accelerate copper oxidation and softening, which may alter the 0.3 oz weight and 0.129 specific gravity, causing the float to sit lower or fail to shut off.
