Banjo Fittings w/ext -4 to 10mm 2pk

The Banjo Fittings w/ext -4 to 10mm 2pk from ALLSTAR PERFORMANCE are precision hydraulic adapter fittings engineered for professional-grade fuel system, brake line, and coolant applications in automotive and motorsport environments. Designed for technicians, mechanics, and fabricators who demand reliability under pressure, these extended banjo adapters bridge the gap between AN (Army-Navy) standard male threads and metric banjo inlet ports commonly found on fuel filters, carburetors, and distribution blocks. Whether you're building a custom fuel system for a race car, restoring a vintage engine, or upgrading a performance platform, this two-pack delivers the versatility and repeatability required for leak-free connections in demanding operational conditions.

Each fitting features a straight 4 AN male thread on one end and a 10mm banjo connection port on the other, constructed from zinc oxide-coated steel for corrosion resistance and durability in both street and track environments. The extended design provides additional clearance in tight engine bays, allowing for proper hose routing without kinks or compression that could restrict flow or compromise system pressure integrity. Zinc oxide plating protects against rust and oxidation while maintaining ease of installation and removal, critical when service intervals demand frequent disconnection. The banjo inlet design distributes fluid flow uniformly across the connection face, reducing turbulence and pressure drop—essential for fuel delivery systems where consistent flow rate directly impacts engine performance and reliability.

Professionals working on fuel-injected engines, high-performance carbureted builds, and custom cooling systems benefit most from this adapter pair, particularly when integrating modern AN-standard fuel lines with older fuel filter housings or aftermarket components that retain metric banjo ports. Installation requires a standard wrench or socket for the 4 AN male end and a banjo bolt (sold separately) to secure the 10mm port—torque specifications should follow OEM guidelines for your specific application to prevent leakage. These fittings are compatible with all standard -4 AN hose and fittings, making them ideal for modular fuel system design where adapter flexibility reduces the need for custom-fabricated lines. The two-pack format suits builders who are plumbing dual fuel filters, redundant cooling circuits, or complete fuel system overhauls where multiple transition points between thread standards are required.
