The Wacker Neuson Grommet is a genuine OEM component designed for the HI and HDR series heaters, including the HI 400HD D Indirect Air Heater, HDR 155 Direct Fired Radiant Heater, HDR 115 Direct Fired Radiant Heater, HDR 45, HI 120, and HI 120HD. As a genuine Wacker Neuson part, the is manufactured to the same standards as the original, ensuring a correct fit the first time. Sourced directly from Wacker Neuson, this grommet is the right choice when maintaining your heater's wiring protection and panel integrity across both indirect and direct-fired models.
Key Features
- OEM-Grade Material Integrity — Manufactured from the same heat- and vibration-resistant elastomer compound as the original, so the grommet maintains its seal and protective shape under sustained heater operating temperatures.
- Drop-In Installation — Molded to the exact opening dimensions of the original mounting hole, this grommet seats securely without trimming or modification to the panel.
- Broad HI and HDR Series Coverage — Confirmed fit across the HI 400HD D, HI 120, HI 120HD, HDR 155, HDR 115, and HDR 45, covering both indirect air and direct-fired radiant heater configurations.
- Wire and Cable Protection — Shields wiring harnesses and cables passing through metal panels from abrasion and chafing, helping preserve electrical continuity in demanding jobsite conditions.
- Electrical Safety Relevance — A cracked or missing grommet exposes wire insulation to sharp panel edges, creating a potential short-circuit or ignition risk in fuel-burning heater equipment; replacement is a critical safety maintenance step.
A grommet is a small but essential protective insert fitted into a hole in a metal panel where wiring, hoses, or cables pass through. Its primary job is to prevent the sharp edges of the panel cutout from cutting into insulation or tubing over time, which can cause electrical faults, fuel leaks, or loss of signal continuity. In heater equipment like the HI and HDR series, where vibration, heat cycles, and outdoor exposure are constant, a degraded or missing grommet accelerates wear on every cable it was protecting — making timely replacement a straightforward way to avoid more costly repairs down the line.
