Bulkhead -6an w5/16in Nipple

The Bulkhead -6AN with 5/16 inch Nipple by ATL Fuel Cells is a precision fuel system component engineered for high-performance and motorsport applications where reliability under pressure is non-negotiable. This bulkhead fitting serves as a sealed pass-through connection point in fuel cell installations, allowing -6AN hose lines to penetrate tank walls while maintaining structural integrity and preventing fuel leakage. Whether you're building a street performance car, a dedicated track machine, or a purpose-built race vehicle, this fitting is essential for creating a clean, professional fuel system architecture.

Manufactured by ATL Fuel Cells—a trusted name in motorsport fuel system solutions—this bulkhead fitting features a -6AN port size (compatible with standard -6AN hose and AN fittings) and integrates a 5/16-inch nipple for secure attachment and sealing. The compact design (2 x 1 x 4 inches) and lightweight construction (0.06 lbs) minimize installation footprint without compromising durability. The nipple component ensures a tight mechanical bond while the bulkhead body provides a robust, leak-proof interface between the fuel cell wall and your feed or return line, critical for maintaining fuel pressure and system consistency during acceleration, braking, and cornering loads.

This fitting is ideal for fabricators, professional mechanics, and serious enthusiasts who demand OEM-grade components in custom fuel cell builds. Installation requires proper sizing of the tank opening to match the nipple dimension and application of fuel-grade sealant for maximum reliability. Compatible with all -6AN hose standards and universal fuel cell designs, the Bulkhead -6AN with 5/16 inch Nipple is a critical element for any fuel system modification seeking longevity, safety, and pressure retention in demanding driving conditions.
