The Wacker Neuson Grommet is a genuine OEM component designed for the HI750, HI900, and HI260 series indirect-fired air heaters, as well as the MC5200 Mobile Drying System. Sourced directly from Wacker Neuson, this grommet meets the exact material and dimensional standards of the original part. It is a direct-fit replacement across a wide range of trailer-mounted, skid-mounted, and mobile indirect air heater configurations. Confirm your model number before ordering to ensure compatibility with your specific unit.
Key Features
- Genuine OEM Material Compliance — Manufactured to Wacker Neuson's original compound and durometer specification, ensuring the grommet seals and cushions correctly under the thermal and vibration loads typical of indirect-fired air heater operation.
- Drop-In Fit for OEM Mounting Points — Matches the original bore diameter and flange profile, so it seats into existing panel or housing cutouts without rework or trimming.
- Broad Heater and Dryer Fitment — Compatible with HI750 (diesel, gas, DGM, and HD surge variants), HI900 (diesel, gas, DGM, and surge brake variants), HI260 oil-fired units, and MC5200 Mobile Drying Systems in both trailer and skid-mounted configurations.
- Protects Wiring and Hose Passages — Prevents abrasion and chafing on cables or lines routed through metal panel openings, maintaining circuit and fluid integrity during extended run cycles in harsh cold-weather jobsite conditions.
- Long-Term Resilience in Temperature Extremes — Grommets in indirect air heaters are exposed to repeated heat cycling and sub-zero ambient temperatures; the OEM-spec elastomer compound resists cracking and compression set over time.
A grommet is a small but critical sealing and protective insert fitted into holes or cutouts in metal panels, frames, or housings. Its primary role is to prevent sharp metal edges from cutting into wiring harnesses, hoses, or tubing that pass through those openings, and to provide a basic environmental seal against moisture, dust, and vibration. In indirect-fired air heaters and mobile drying systems like the HI750, HI900, HI260, and MC5200, where electrical routing and fuel or fluid lines run through heavy-gauge steel enclosures, a degraded or missing grommet can allow chafing that leads to shorts, fluid leaks, or accelerated wire insulation failure — all of which can take a heater unit out of service at the worst possible time.
