Custom Firewall Rubber Grommets
Firewall Rubber Grommets Product Overview
Firewall rubber grommets are sealing components installed in holes of metal firewalls, bulkheads, or panels to protect wires, cables, and hoses passing through. They prevent abrasion caused by sharp panel edges, and create a barrier against heat, exhaust fumes, moisture, and engine compartment noise. Widely used in automotive, marine, HVAC, and industrial machinery applications.
Key Features:
- High-temperature resistance (up to 200°C+ for silicone grades)
- Oil, fuel, and chemical resistance (NBR, FKM options)
- Flame-retardant grades available (UL94 V-0)
- Dual-lip design for tight snap-in panel fit
- Custom inner diameter, outer diameter, and groove depth
- Compression molded or injection molded options
Common Applications:
- Automotive firewall & bulkhead wiring pass-through
- Engine bay cable and hose protection
- Marine and RV electrical systems
- HVAC ductwork panel feedthrough
- Industrial control cabinet grommet sealing
- Agricultural and off-highway equipment
