Flush Mount Aircraft Cap Poly.

The Flush Mount Aircraft Cap Poly from ATL Fuel Cells is a precision fuel cell cap designed for automotive applications. This component serves as a sealing interface for custom builds and modified vehicles where reliability and aerodynamic integrity are important. Whether you're restoring a classic vehicle or engineering a custom hot rod, this flush-mount cap provides a low-profile solution that enhances both performance and aesthetics.

Engineered from durable polymer construction, the flush mount design integrates seamlessly with fuel cell tanks, providing a clean installation that reduces drag and maintains a finished appearance. The material resists fuel degradation, vibration fatigue, and thermal cycling—essential characteristics for various automotive environments. At just 0.94 lbs and measuring 5.4 x 2.65 x 5.5 inches, this cap fits snugly within modern fuel cell tank configurations while ensuring secure sealing against fuel vapor loss and contamination.

This cap is ideal for automotive enthusiasts upgrading to aftermarket fuel cells, whether for street performance or custom builds. Mechanics and fabricators appreciate the flush-mount design, which eliminates external protrusions critical for vehicles with tight engine bay layouts or aerodynamic bodywork. Its versatility makes it a valuable addition to any automotive project.
