The Wacker Neuson Pipe is a genuine OEM component designed for the HI 400HD G Indirect Air Heater. As a direct factory replacement, this pipe is manufactured to the same specifications as the original part, ensuring a correct fit within the heater's fuel or air delivery circuit. If your current pipe has cracked, corroded, or developed a leak, swapping it out with the OEM restores the system to its original operating condition. Trust the genuine Wacker Neuson part to deliver the fit and function your equipment demands.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional standards, ensuring the pipe handles the thermal and pressure demands of indirect-fired heater operation.
- Direct-Fit Replacement — Matches the original routing, end connections, and diameter of the factory-installed pipe, allowing straightforward installation without modification.
- Confirmed Fitment — Verified for the HI 400HD G Indirect Air Heater, so you can order with confidence knowing this is the correct part for your machine.
- Leak-Free Circuit Integrity — A sound, correctly seated pipe keeps the heater's fuel or air pathway sealed, maintaining consistent heat output and combustion efficiency across extended cold-weather operations.
- Fuel System Safety — In a diesel-fired indirect heater, a compromised pipe can lead to fuel leaks or combustion irregularities. Using the genuine OEM replacement maintains the integrity of the fuel delivery path and supports safe heater operation.
In an indirect-fired air heater like the HI 400HD G, pipes route fuel, air, or combustion exhaust between key components of the heating circuit. A pipe in good condition maintains a sealed, unobstructed flow path that allows the burner to operate at its designed efficiency and deliver consistent warm air output. When a pipe cracks, corrodes, or develops a leak, it can disrupt combustion, reduce heat output, or create a fuel-leak hazard — making timely replacement essential to both performance and safety.
