Float Ball for Automatic Watering Systems

This copper float ball is designed for use with automatic watering kits, stems and nozzle assemblies. It provides reliable liquid-level control in tanks or reservoirs. The 4-inch diameter float suits a range of agricultural and industrial installations. It is supplied new and ready for installation.

Internal Connection and Thread Compatibility

The float features an internal connection with a 1/4 In.-20 thread size for secure attachment to valve stems or lever arms. A float weight of 0.56 oz and specific gravity of 0.22 ensure proper buoyancy and actuation force. These specifications determine how the accessory interacts with the host mechanism.

Verify Temperature and Thread Requirements

Confirm that the maximum liquid temperature of 200 Degrees F meets the demands of your application. Ensure the mating component uses a matching 1/4 In.-20 thread for correct fitment. Buyers who need a different thread pitch or higher temperature rating should select an alternative model.

Questions about this item

Will the 1/4-20 internal thread on this copper float ball wear out and need replacement?

The 1/4-20 internal thread is machined into the copper body; under normal water conditions it does not require scheduled replacement.

What is the first limit reached when this float ball operates continuously at high temperature?

The maximum liquid temperature is 200 degrees F; exceeding this limit will degrade the copper and the internal connection first.

How much heat does this float ball add to the system when it runs all day?

The copper float ball itself generates no heat; it simply floats on liquid up to 200 degrees F without adding thermal load.
