The Honda 31482-ZB4-003 Main Wire Grommet is a genuine OEM component designed for EB3500, EB5000, EB6500, EM3500, EM5000, EX3300, and EX4500 generators, as well as GX240, GX340, and GX390 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the exact specification of the original, ensuring a correct fit the first time. Verify your model and serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct grommet varies by production run.
Key Features
- Genuine OEM Construction — manufactured by Honda to the same specification as the original, ensuring the correct dimensional fit for the wire passage it protects
- Broad Fitment — covers EB3500, EB5000, EB6500, EM3500, EM5000, EX3300, and EX4500 generators, and GX240, GX340, and GX390 horizontal shaft engines
- Serial Number Verification Recommended — Honda updates parts at production breaks, so confirm your machine's serial number against the fitment table to ensure this is the right grommet for your unit
- Wiring Integrity — a properly seated grommet shields the main wire harness from chafing and abrasion at the panel or housing pass-through; a cracked or missing grommet leaves insulation vulnerable to damage that can cause electrical faults
A wire grommet is a fitted rubber or synthetic ring seated into a hole in a metal housing or panel wherever a wire or wire harness passes through. Its job is to prevent the sharp edge of the hole from cutting into the wire's insulation, and to keep moisture and debris from migrating along the harness into the enclosure. On Honda generators and horizontal shaft engines, the main wire grommet protects the primary electrical harness at the point where it exits or enters the frame or control panel. When a grommet cracks, shrinks, or goes missing, the wire insulation is exposed directly to a metal edge and to the elements — over time, this leads to chafed wiring, short circuits, and intermittent electrical faults that can be difficult to diagnose.
