The Wacker Neuson Flange Complete is a genuine OEM component designed for the HI 770 XHD indirect-fired diesel air heater series. This includes Arctic Bear XHD, Arctic Bear XHD NS, and standard HI770XHD configurations across multiple machine variants. As a direct OEM replacement, the is manufactured to the same specifications as the original part, ensuring a proper fit and correct sealing within the heater assembly. If your HI 770 XHD is showing signs of exhaust or airflow path issues, replacing a worn or damaged flange with the correct part is a straightforward path to restoring full heater operation.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional specs, so the flange seats and seals correctly without gaps or misalignment in the heat exchanger pathway.
- Drop-In Replacement — Matches the original bolt pattern and mating surfaces of the HI 770 XHD assembly, allowing straightforward removal and reinstallation without rework.
- Broad HI 770 XHD Coverage — Compatible with Arctic Bear XHD, Arctic Bear XHD NS, and HI770XHD variants across multiple duct configurations including 1x16, 1x20, and 2x12 setups.
- Sustained Heat Output — A properly sealed flange maintains the integrity of the combustion and airflow circuit, allowing the heater to deliver consistent, rated heat output in cold-weather job conditions.
- Combustion System Safety — In an indirect-fired heater, flange integrity is critical to keeping exhaust gases separated from the heated air stream — making correct fitment a safety consideration, not just a performance one.
In an indirect-fired air heater like the HI 770 XHD, the flange serves as a critical connection point within the combustion and airflow circuit — sealing and joining sections of the burner or heat exchanger assembly so exhaust gases and heated air remain properly routed. A complete flange assembly includes all mating hardware needed to form a tight, leak-resistant joint. When a flange warps, cracks, or corrodes, it can allow exhaust gases to migrate into the heated air stream or cause heat loss that reduces the unit's output capacity — both of which compromise heater performance and safety on site.
