The Wacker Neuson Flange is a genuine OEM component designed for the HI 400HD G, HI 400HD D, HI 120, and HI 120HD indirect-fired air heaters. Sourced directly from Wacker Neuson, this flange meets the exact specifications of the original part it replaces. It fits seamlessly into its mounting position across the HI 120 and HI 400HD series, ensuring a correct, secure connection every time. Confirm your model number before ordering to ensure proper fitment.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the correct seal surface and bolt pattern for a leak-free, structurally sound connection in a high-temperature heater environment.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the original flange; mounts to the same bolt pattern and interfaces without any rework or modification to adjacent components.
- Broad HI Series Compatibility — Fits the HI 400HD G, HI 400HD D, HI 120, and HI 120HD indirect-fired air heaters, covering both standard and heavy-duty variants across the HI product family.
- Sustained Airflow Integrity — A correctly installed flange maintains an airtight connection in the heater's air or exhaust pathway; a damaged or warped flange can cause heat loss, pressure leakage, or combustion inefficiency that reduces heater output.
- Combustion System Safety — In an indirect-fired heater, a compromised flange joint can allow exhaust gases or combustion byproducts to escape into the heated air stream. Using the correct OEM flange helps maintain the separation between combustion and output air that these units are designed to deliver.
A flange is a flat or collar-style fitting that joins two sections of ductwork, piping, or housing within the heater assembly, creating a secure, sealed connection point. In an indirect-fired air heater like the HI series, flanges are critical for maintaining the integrity of both the air delivery path and the combustion exhaust routing — keeping heat output consistent and combustion gases properly contained. When a flange warps, cracks, or develops a compromised sealing surface, it can result in air or exhaust leaks that reduce heating efficiency and may affect safe operation of the unit.
