Firewall Grommet -8an

The SEALS-IT Firewall Grommet -8AN (part number GS10038) is a precision engineered firewall pass-through component designed for high-performance fluid transfer systems in automotive, marine, and industrial applications. This single-hole grommet features a 3-inch outer diameter with a 0.5-inch inner diameter opening and 0.12-inch wall thickness, providing a secure, sealed transition for -8AN hose or tubing through engine firewalls or bulkheads while maintaining system integrity under pressure.

Constructed from a durable aluminum and rubber composite with black and natural finish, this firewall grommet combines structural strength with vibration dampening and thermal isolation. The rubber component protects against chafing and abrasion while the aluminum collar provides rigidity and corrosion resistance in demanding environments. The 0.03-pound weight reflects its compact, lightweight design—critical for applications where mass matters. The combination of materials makes this grommet suitable for fuel systems, coolant lines, hydraulic circuits, and custom fluid delivery applications across motorsports, marine propulsion, and industrial equipment.

SEALS-IT grommets are engineered for builders and technicians who require reliable firewall penetrations without fluid weeping or system degradation. Applications range from high-performance street and race vehicles to marine engine compartments where salt spray and thermal cycling demand durable sealing solutions. The -8AN sizing integrates seamlessly with standard AN hose fittings and tubing standards, ensuring compatibility with existing fluid transfer systems. Whether configuring a custom fuel cell installation, upgrading a cooling circuit, or fabricating hydraulic steering or brake systems, this grommet provides the sealed passage point that prevents costly leaks and maintains system cleanliness.
