The Wacker Neuson Grommet is a genuine OEM component designed for the HI770XHD Indirect Air Heater series, including Arctic Bear XHD and Arctic Bear XHD NS configurations, as well as MC5200 Mobile Drying System units. Sourced directly from Wacker Neuson, this grommet matches the exact material grade and dimensional spec of the original part installed at the factory. Compatible across multiple HI770XHD configurations, part number is the correct replacement for both diesel-fired indirect heater and mobile drying system applications. When a worn or damaged grommet lets you down on a cold-weather job, this is the part that gets your equipment back to full operation.
Key Features
- Genuine OEM Material Match — Molded to the same durometer and heat-resistance spec as the original, ensuring the grommet holds its seal and shape under the elevated temperatures typical of diesel indirect-fired heater operation.
- Drop-In Replacement — Seats into the same mounting aperture as the factory-installed grommet on HI770XHD and MC5200 units, requiring no trimming or modification to the housing.
- Broad HI770XHD Series Coverage — Fits the HI770XHD Indirect Air Heater (1x16 and 2x12 diesel configurations), Arctic Bear XHD, Arctic Bear XHD NS, and MC5200 Mobile Drying System models.
- Protects Wiring and Hose Passages — A correctly fitted grommet prevents chafing and abrasion damage to cables or hoses routed through panel openings, an important consideration in high-vibration heater and drying-system environments.
- Fuel and Heat System Compliance — Using the correct OEM grommet in fuel-line and combustion-air passages helps maintain the integrity of the heater's sealed enclosure, supporting safe and efficient diesel burner operation.
A grommet is a small but critical sealing and protection insert fitted into holes or openings in sheet metal panels, enclosures, or bulkheads. Its primary job is to protect wiring harnesses, fuel lines, or air hoses from the sharp edges of the opening they pass through, preventing chafing, cuts, and eventual failure of those components. In diesel indirect air heaters like the HI770XHD and in mobile drying systems like the MC5200, grommets also help maintain the integrity of the enclosure against heat, vibration, and moisture. When a grommet cracks, hardens, or falls out, the cables or lines it was protecting become vulnerable to abrasion damage — which can lead to electrical faults, fuel leaks, or air system inefficiencies that affect burner performance.
