The SEALS-IT Firewall Grommet -12AN (part number GS100312) is a precision-engineered aluminum and rubber pass-through grommet designed to seal and protect fluid lines passing through engine firewalls and bulkheads. This grommet is essential for applications in marine engine installations, custom automotive fuel and coolant systems, and hydraulic fluid routing where firewall penetration is unavoidable.
With an outer diameter of 3.25 inches, an inner diameter of 0.75 inches, and a wall thickness of 0.12 inches, this single-hole grommet provides a watertight barrier while accommodating 12AN hose connections. The dual-material construction features an aluminum outer ring with a natural rubber sealing surface, delivering chemical resistance and durability across various fluid systems.
This grommet's design ensures consistent performance across thermal cycles, from cold-soak conditions to engine-bay temperatures. The -12AN specification indicates compatibility with 12AN (3/4-inch outer diameter) hose standards commonly found in performance automotive, marine propulsion, and industrial hydraulic applications.
