Gasket Fill Neck 12-Hole for Aluminum Cells

The RCI Gasket Fill Neck 12-Hole for Aluminum Cells (SKU RCI0113) is a precision fuel cell filler plate gasket designed for high-performance circle track racing and motorsport applications. This component serves as the critical seal between your fuel cell and fill neck assembly, preventing fuel leakage during high-G cornering, acceleration, and braking events.

Built to RCI's exacting standards, this gasket features a durable cork material that resists fuel saturation, thermal cycling, and mechanical stress over extended use. The circular design with precisely machined bolt holes ensures uniform clamping load distribution across the fill neck interface, eliminating hot spots and micro-leaks that compromise fuel containment. Cork remains a widely used material for fuel cell gaskets due to its ability to compress consistently and maintain sealing integrity across temperature ranges encountered in motorsport.

Racers and fuel system technicians should replace the RCI Gasket Fill Neck 12-Hole whenever disassembling fuel cell fill systems, as gasket material degrades with fuel exposure and thermal cycling. Reusing old gaskets risks seepage that can saturate fuel containment foam or contaminate the fuel system. This gasket is specifically compatible with RCI aluminum fuel cells, making it an essential maintenance item for teams focused on reliability and safety.
