Gasket 4-3/4in BC 12 Bolt

The Gasket 4-3/4in BC 12 Bolt from ATL Fuel Cells is an essential component for high-performance fuel cell installations, specifically designed for applications requiring a secure, leak-free seal on 12-bolt fuel cell baffles and mounting systems. If you're building a custom race car, performance street machine, or professional motorsport vehicle, this gasket delivers the reliability and precision fit that separates amateur builds from championship-caliber engineering. ATL Fuel Cells has been the trusted name in motorsport fuel containment for decades, and their gasket specifications reflect that commitment to durability under extreme conditions.

This 4-3/4-inch diameter gasket is engineered to maintain a perfect seal across the baffle plate interface of 12-bolt fuel cell designs, preventing fuel weeping, vapor loss, and internal contamination during high-G cornering and aggressive acceleration. The compact 0.15-inch thickness allows for precise stack-up tolerances while the engineered material composition resists fuel degradation, temperature cycling, and vibration-induced creep that would compromise inferior gaskets. Proper gasket selection in fuel cell assembly is non-negotiable—a failed seal can result in fuel starvation during critical race moments, fire hazard, or environmental contamination. ATL's specification ensures dimensional consistency (5.95 x 0.15 x 6.4 inches) so your fuel cell assembly torques down to OEM-equivalent pressures without over-clamping or under-seating.

Whether you're a professional fabricator, weekend racer, or dedicated enthusiast upgrading to a fuel cell from a stock fuel tank, this gasket is critical for any 12-bolt ATL Fuel Cell baffle assembly. Installation requires careful attention to bolt torque sequence and pattern to ensure even pressure distribution—use a star or cross pattern and verify tightness after heat cycling. This gasket is not a wear item to be overlooked; it's the foundation of fuel system integrity in a competition or modified vehicle. For fuel cell builds prioritizing safety, performance, and leak-free operation, the Gasket 4-3/4in BC 12 Bolt is the OEM-grade choice that professional shops and experienced builders specify.
