Watts 0780320 Float Stem

When you are managing high-capacity water levels in commercial cooling towers or livestock watering tanks, the Watts 0780320 Float Stem provides the structural rigidity required for heavy-duty float valve assemblies. This 12-inch brass float stem features a 5/16-inch outside diameter, making it significantly more robust than standard 1/4-inch rods often found in residential kits. Engineered from high-grade heavy-duty brass, this component is designed to resist corrosion in demanding HVACR and industrial environments. The stem is equipped with 5/16-18 NPT threads on both ends, ensuring a secure and vibration-resistant connection between the float ball and the valve plunger. As a direct replacement for Watts KSTEM-12, it is compatible with the Watts Series 1000 float valves, facilitating precise fluid level control in high-flow applications. Integrating this genuine OEM replacement part ensures your system maintains its original design pressure ratings and mechanical integrity without the risk of rod bending or thread failure under hydraulic surges.

• Heavy-Duty Construction: Built from solid brass to withstand constant immersion and prevent rod deflection in high-velocity 12-inch tank applications.
• Enhanced Compatibility: Precisely threaded for Watts 0780320 and Watts 1000 float valves, serving as a drop-in HVAC replacement part.
• Reliable Level Control: The 12-inch length provides the necessary leverage for high-capacity valves used in agricultural and commercial cooling systems.
• Industrial Standard Threads: Features 5/16-18 NPT ends to eliminate the need for adapters during routine maintenance or float valve repair.

What is the thread size for the Watts 0780320?
This stem uses 5/16-18 NPT threads on both ends, which is the standard for Watts heavy-duty float components. Always confirm your float ball and valve body accept 5/16" threads, as some standard models use 1/4-20 threading.

Is this stem compatible with refrigeration cooling towers?
Yes, this brass valve stem is frequently utilized in cooling tower basins and refrigeration units where high-capacity water flow and chemical resistance are critical for consistent operation.

Can I use this for non-Watts valves?
While designed as a Watts 0780320 replacement, it works with any 3/4" to 2" float valve system that specifies a 5/16" diameter rod with matching NPT threads.
