Dorman 90302 Rubber Diaphragm Grommet 3/4-Inch

The Dorman 90302 is a 3/4-inch rubber diaphragm grommet designed for professional-quality electrical installations and repairs. This component allows wiring and cables to pass cleanly and safely through sheet metal panels such as firewalls, floors, and bulkheads while protecting the wire from abrasion and preventing moisture intrusion.

Key Features:

• 3/4-inch diameter opening for wire passage
• Flexible rubber construction creates a secure, weather-resistant seal
• Diaphragm design allows wires to be pushed through without removing connectors
• Protects wiring from sharp metal edges and prevents chafing
• Ideal for automotive, marine, and RV electrical installations
• Part of Dorman's Builders Series of professional-grade components

This diaphragm grommet features a flexible center membrane that can be pierced to accommodate various wire gauges, making it versatile for different applications. The rubber material provides vibration dampening and maintains a tight seal around the wire bundle, keeping moisture, dirt, and debris out of sensitive areas.
