The Watts 0780021 N1-NA Nozzle Assembly is a specialized service component designed for precision performance in exposed cattle watering systems and agricultural float valve applications. This assembly serves as a direct, high-durability replacement for the legacy Watts N1 model, featuring a rugged brass body construction engineered to withstand the demanding environments of livestock management. The technical configuration includes a 1/4-20 TPI threaded stem and a matching 1/4-20 thumb screw, integrated with a 10-inch float rod. This specific "flippen" type design utilizes a swivel joint and dedicated hooks to allow the float ball to move freely. This mechanical decoupling ensures that cattle can nuzzle the ball without triggering the valve prematurely or causing mechanical fatigue. For contractors, the brass nozzle assembly provides a corrosion-resistant solution that maintains consistent 1/4-inch float valve alignment, preventing common issues like short-cycling or improper tank levels in livestock waterer installations. Key Benefits Direct N1 Replacement: Drop-in compatibility for existing Watts N1 configurations ensures fast field service without needing to modify the tank setup. Durable Brass Design: Optimized for high-moisture agricultural environments where standard hardware often faces premature oxidation and failure. Nuzzle-Proof Mechanics: The specialized swivel joint allows livestock interaction with the float ball without stressing the valve seat or causing erratic water discharge. Precise Level Control: Standard 1/4-20 threading provides a secure, adjustable connection for 10-inch rods, maintaining accurate hydraulic shut-off. Common Questions Is this compatible with standard plastic float balls? Yes, the 1/4-20 threaded stem is international standard for most industrial and agricultural float balls, though it is specifically optimized for the Watts PX series. Can this be used in high-pressure burner applications? No. While many "nozzle assemblies" refer to oil burners, this specific Watts 0780021 is exclusively for agricultural water float valves. Always verify part numbers against the original equipment manufacturer (OEM) specs before installation. Does the assembly include the float ball? This SKU consists of the brass nozzle assembly, thumb screw, hooks, swivel joint, and rod. The float ball is typically sold separately to allow for varying buoyancy requirements.
