The Honda 31483-ZB4-003 Switch Wire Grommet is a genuine OEM component designed for a range of Honda generators, welder generators, and horizontal shaft engines. This includes the EB3500, EB5000, and EB6500 generators, the EM3500 and EM5000 generators, the EW140 and EW171 welder generators, and the GX240, GX340, and GX390 horizontal shaft engines. As an authentic Honda part, this grommet is manufactured to the same specifications as the original, ensuring a proper fit without the guesswork of sourcing an alternative. Confirm your model and serial number against the fitment table before ordering to make sure this is the correct grommet for your unit.
Key Features
- Genuine OEM Integrity — sourced directly from Honda, this grommet matches the original in shape, size, and material — no trimming or modification needed for installation
- Broad Fitment — fits Honda EB3500, EB5000, and EB6500 generators; EM3500 and EM5000 generators; EW140 and EW171 welder generators; and GX240, GX340, and GX390 horizontal shaft engines
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-check your machine's serial number against the fitment table to confirm this is the right grommet for your build
- Wire Protection Where It Counts — a correctly seated grommet prevents the switch wire harness from chafing against a sharp panel edge, protecting insulation and maintaining a clean electrical connection
A switch wire grommet is a small rubber or elastomeric bushing fitted into a panel opening where a wire or wiring harness passes through the housing. Its job is to cushion and protect the wire's insulation from the sharp edges of the panel hole — without it, vibration and movement cause the insulation to wear through, which can lead to a short circuit or an intermittent electrical fault. On generators and welder generators, where switch wiring runs through metal housings subject to constant engine vibration, a sound grommet is essential to keeping the electrical system functioning correctly. On GX-series horizontal shaft engines, it serves the same protective role wherever switch wiring exits the engine housing.
