The Wacker Neuson Filler Tube Weldment is a genuine OEM component designed for the HI260, HI750, HI900, and HI1000 series indirect-fired air heaters. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a proper fit within the fuel fill assembly. This weldment is compatible across a wide range of HI-series configurations, including diesel, natural gas, and dual-fuel DGM variants, as well as skid-mounted and trailer-mounted units. Verify your model number before ordering to confirm fitment with your specific machine configuration.
Key Features
- Genuine OEM Weld Integrity — Fabricated to original weld specifications, ensuring the structural integrity and leak-free performance expected from the fuel fill pathway on HI-series heaters.
- Direct-Fit Installation — Engineered to the exact dimensions of the original filler tube assembly, connecting directly to the existing fuel system without rework or modification to surrounding components.
- Broad HI-Series Compatibility — Fits HI260, HI750, HI750GM, HI750GMHD, HI900, HI900DGM, HI1000, HI1000DGM, and HIF600 indirect air heater models across diesel, natural gas, and dual-fuel configurations.
- Sustained Fuel Flow Performance — A sound filler tube weldment maintains proper fuel delivery to the burner system; a cracked or corroded weldment can disrupt fuel fill operations and introduce leak risk in cold-weather heating applications.
- Fuel System Safety — As a component within the fuel fill circuit of a combustion-based heater, using a correctly rated OEM weldment helps maintain the integrity of the sealed fuel pathway and reduces the risk of fuel spillage or vapor exposure.
The filler tube weldment serves as the structural conduit through which fuel is introduced into the heater's tank or fuel supply system. It connects the fill point to the internal fuel circuit and must maintain a sealed, rigid connection to prevent leaks during fueling and operation. On indirect-fired air heaters like the HI-series, which operate in demanding cold-weather environments, a compromised or cracked weldment can lead to fuel seepage, difficult fueling, or contamination — making timely replacement critical to safe, continuous heater operation.
