The Wacker Neuson Grommet is a genuine OEM component designed for the HI-series indirect air heaters, including the HI400HD, HI300HD, HI200D, HI110HD, and related HD and standard configurations. As a factory-sourced part, it meets the exact material and dimensional specifications set by Wacker Neuson for these diesel-powered portable heating units. This grommet also fits select HDR-series direct-fired radiant heaters and HD-series units, making it a widely applicable service part across the Wacker Neuson portable heating lineup. Keep part number on hand for scheduled maintenance or field repairs to keep your heater running through cold-weather operations.
Key Features
- OEM Material Compliance — Manufactured to Wacker Neuson's original compound and hardness specification, ensuring the grommet seals and cushions correctly without cracking or deforming under heat cycling.
- Drop-In Installation — Sized to seat directly into the original mounting location with no trimming or modification, matching the original bore and shoulder dimensions exactly.
- Broad HI-Series Fitment — Compatible with HI400HD, HI300HD, HI200D, HI110HD, HI90, HI120, and additional HD-D variants, as well as HDR and HD portable heater models.
- Protects Wiring and Fuel Lines — Grommets prevent sharp panel edges from abrading cables or hoses routed through bulkheads; a missing or split grommet can lead to chafed wiring and fuel line damage in high-vibration heating environments.
- Genuine OEM Part — Sourced directly through the Wacker Neuson parts network under part number 5000183953, so you can order with confidence that you're receiving the correct replacement.
A grommet is a small but essential sealing and protective insert fitted where wiring, fuel lines, or hoses pass through a metal panel or bulkhead opening. It cushions the routed component against the hard edge of the hole, preventing abrasion wear that can strip insulation from electrical wires or nick fuel-line tubing over time. On diesel indirect air heaters — which operate in demanding cold-weather environments and generate significant vibration — a compromised or missing grommet can allow a wire or hose to chafe through quickly, leading to fuel leaks, electrical faults, or heater shutdown at exactly the wrong moment.
