Top Plate Gasket 4x6 Rubber 12 Hole

The Top Plate Gasket 4x6 Rubber 12 Hole is a precision fuel cell fill plate gasket engineered for high-performance racing and motorsport applications where fuel containment and safety are non-negotiable. This component seals the top plate of a fuel cell assembly, preventing fuel vapor leakage and maintaining system integrity under extreme conditions. Whether you're building a purpose-built race vehicle, maintaining competition equipment, or upgrading a custom fuel system, this gasket ensures reliable performance and regulatory compliance.

Manufactured from durable black rubber, the Top Plate Gasket 4x6 Rubber 12 Hole features twelve bolt holes positioned to create a secure, uniform seal across the 3.485 x 5.5-inch oval face. The rubber construction provides excellent chemical resistance to fuel and oil while maintaining flexibility under thermal cycling—critical when fuel temperatures fluctuate during extended racing sessions. The precise 4x6-inch overall gasket dimensions and strategically spaced mounting holes ensure proper alignment with standard fuel cell fill plates, eliminating gaps that could compromise fuel containment or allow contaminant ingress.

This gasket is essential for motorsport competitors, restoration specialists, and fabricators installing aftermarket fuel systems in race vehicles, off-road platforms, and high-performance street machines. Installation requires only basic mechanical skill: position the gasket on the fill plate, align the twelve bolt holes, and torque fasteners in a star pattern to ensure even sealing pressure. The lightweight 0.05-pound design adds negligible weight while delivering the fuel containment integrity demanded by sanctioning bodies and safety-conscious builders worldwide.
