Fillcap Screw-on 3in Dia Weld-On - Black

The Fillcap Screw-on 3-inch Diameter Weld-On in black anodized aluminum is designed for fuel cell and tank installations requiring a secure and corrosion-resistant closure. This product is ideal for custom fuel system builds where a welded attachment is preferred, providing a robust alternative to traditional bolt-on systems.

The raised cell mount design allows for easy installation and improved clearance for surrounding components, making it suitable for high-vibration environments. The screw-on closure mechanism ensures quick access and easy removal without the need for tools, while the black anodized aluminum construction resists corrosion from fuel vapors and moisture.

This assembly is perfect for high-performance racing builds, marine fuel systems, and restoration projects where OEM caps may not fit or be available. Its lightweight design, weighing only 0.9 pounds, integrates seamlessly into various fuel systems without adding unnecessary mass.
