Watts 0780319 Stem

The Watts 0780319 is a heavy duty brass threaded stem engineered for high-capacity fluid management in commercial, industrial, and agricultural tank systems. Known by its manufacturing model KSTEM-11.5, this component is structurally identical to 11.5 inch variations and features a precise 12-inch overall length. Specifically designed for HVACR and plumbing contractors, the stem utilizes a 1/4-20 NPT threaded end for secure attachment to the valve body and a 5/16-18 NPT threaded end for the float, providing a rigid link necessary for accurate liquid level control. The 5/16-inch OD rod diameter ensures torsional strength under high flow rates, preventing the float valve stem from bending or vibrating during operation. This Watts replacement part is the standard for maintaining automatic water level control, particularly in systems where high-temperature resistance up to 9,999° F (material limit) is a technical factor. Rely on this brass float rod for direct compatibility and long-term mechanical reliability in demanding field applications.

• Universal Compatibility: Direct drop-in replacement for any system requiring the KSTEM-11.5 or 0780319 series.
• Precision Threading: Dual ends with 1/4-20 and 5/16-18 NPT threads ensure a leak-proof, vibration-resistant connection.
• Structural Integrity: 5/16" Outer Diameter heavy-duty brass construction tolerates high-capacity water flow without deformation.
• Chemical Resistance: Solid brass build is suitable for a wide range of water conditions in industrial and agricultural settings.

• Is the Watts 0780319 interchangeable with other 12-inch stems? Yes, this model is specifically designed to be identical to the 11.5 series, provided the 5/16" thread and OD requirements are met.
• What is the thread pitch for the valve and float ends? The stem features a 1/4-20 inch NPT end for the valve connection and a 5/16-18 inch NPT end for the float bulb.
• Can this be used in high-temperature applications? While primarily used for water level control, the brass construction is technically rated for extreme temperature thresholds in specialized industrial environments.
