The Wacker Neuson Tube is a genuine OEM component designed for the HI110HD D, HI110D, and HI35 indirect-fired diesel air heaters. As a direct Wacker Neuson OEM part, it is manufactured to the exact specifications of the original, ensuring a correct, hassle-free installation. This tube is a critical element within the heater's internal fuel or air flow path, and sourcing the correct part number is essential for maintaining safe, efficient heater operation. Confirm your model number against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to original design tolerances, ensuring the correct material grade and dimensional accuracy expected for fuel and air routing components in diesel heater applications.
- Direct Drop-In Replacement — Engineered to connect and seat exactly as the original tube, with matching end fittings and routing geometry that align with the existing assembly in the heater.
- Broad HI-Series Compatibility — Fits the HI110HD D, HI110D, and HI35 indirect-fired diesel air heater models, covering multiple units within Wacker Neuson's HI heater family.
- Supports Consistent Heat Output — A correctly seated and undamaged tube maintains the intended flow path within the heater system, helping the unit deliver steady, uninterrupted warm air output on the jobsite.
- Fuel System Integrity — In diesel indirect heaters, tube condition directly affects safe fuel delivery and combustion; a cracked, kinked, or degraded tube can cause fuel leaks or combustion irregularities, making timely replacement important for safe operation.
In an indirect-fired diesel air heater, tubes route fuel, coolant, or combustion air between key components within the heater assembly. A tube in this application must maintain a sealed, unobstructed path under thermal cycling and vibration — conditions common in construction heating environments. When a tube cracks, collapses, or develops a leak, it can disrupt fuel delivery, reduce heat output, or create a safety hazard, making it one of the more important service items to inspect and replace as part of routine heater maintenance.
