Wacker Neuson 5000172663 Nozzle Fitting

The Wacker Neuson Nozzle Fitting is a genuine OEM component designed for the CUB400, CUB700, CUB700GM, CUB700M, and MC5200 series indirect-fired air heaters and mobile drying systems. As a direct OEM replacement, part is manufactured to the same specification as the original, ensuring a correct fit within the fuel delivery and combustion circuit. This fitting is compatible across a wide range of Wacker Neuson diesel-powered portable, skid-mounted, and mobile indirect-fired heater configurations.

Key Features

• OEM Fuel Path Integrity — Genuine OEM construction ensures correct flow geometry and thread spec for the nozzle circuit, maintaining consistent fuel delivery to the burner.
• Direct-Fit Replacement — Engineered to mate precisely with the existing nozzle assembly mounting point, connecting without modification to the heater's fuel line and burner head.
• Broad Series Compatibility — Fits CUB400, CUB700, CUB700GM, CUB700M, and MC5200 units, covering portable, skid-mounted, and mobile indirect-fired diesel heater and drying system variants.
• Combustion Efficiency Support — A correctly seated nozzle fitting maintains the fuel atomization path; a worn or leaking fitting can disrupt spray pattern, leading to incomplete combustion and reduced heat output.
• Fuel System Safety — In a pressurized diesel fuel circuit, a properly sealed fitting is critical to preventing fuel leaks at the nozzle connection point, protecting both equipment and operators.

The nozzle fitting serves as the threaded connection point between the fuel supply line and the burner nozzle in a diesel indirect-fired air heater. It channels pressurized fuel to the nozzle tip where it is atomized and ignited to produce heat — meaning a secure, leak-free fitting is essential to stable burner operation. If this fitting becomes cracked, corroded, or loses its seal, fuel delivery to the nozzle is compromised, which can cause ignition failure, erratic flame behavior, or dangerous fuel leakage in the heater's combustion chamber.
