Grommets
Grommets are small but essential components for any automotive wiring or plumbing job. Our collection includes a variety of rubber grommets, plastic grommets, and firewall seals designed to protect cables, hoses, and wires from sharp edges and vibration. Whether you're passing a sensor wire through the firewall, sealing a bulkhead, or tidying an engine bay harness, the right grommet prevents chafing, moisture ingress, and electrical shorts.
- Standard round grommets for wire and hose pass-through
- Blanking grommets to plug unused holes
- Split grommets for easy retrofit without disconnecting connectors
- Materials resist oil, fuel, and underhood temperatures
To choose the correct grommet, measure your panel hole diameter and material thickness. Need help? Our product listings include detailed dimensions for each part.
