The Wacker Neuson Tube is a genuine OEM component designed for the HI 400HD D, HI 120, and HI 120HD indirect-fired air heaters. As a direct factory replacement, this tube is built to the same specifications as the original part, ensuring a proper fit within the heater's internal assembly. Sourced directly from Wacker Neuson, part delivers the consistency and accuracy that keeps your heating equipment running at full capacity on the jobsite.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original dimensional and material specifications, so the tube seats, seals, and flows exactly as intended within the heater circuit.
- Drop-In Replacement: — Engineered to match the original tube's form and connection points, allowing straightforward installation without reworking surrounding components.
- Broad HI Series Compatibility: — Verified fitment across the HI 400HD D, HI 120, and HI 120HD indirect-fired air heater models.
- Sustained Heat Output: — A sound, unobstructed tube maintains proper fluid or air routing through the heater core, preserving consistent heat delivery; a cracked or degraded tube can cause loss of output or uneven heating.
- Fuel System Integrity: — On indirect-fired heaters, tube condition directly affects the safe containment and routing of fuel or heated fluid — using a genuine OEM replacement upholds the original design intent for safe heater operation.
On an indirect-fired air heater, internal tubes route fuel, combustion gases, or heated fluid through the heat exchanger assembly, allowing heat to transfer to the outgoing airstream without mixing combustion byproducts into the air supply. This design is critical for enclosed or occupied workspaces where clean, breathable heated air is required. When a tube cracks, corrodes, or becomes blocked, heat transfer efficiency drops and the integrity of the sealed combustion circuit is compromised — making timely replacement essential to both performance and safe operation.
