Single Male Banjo Adaptr Bolt M12x1.25 to -4AN

The Single Male Banjo Adapter Bolt M12x1.25 to -4AN by VIBRANT PERFORMANCE is a precision hydraulic fitting adapter designed for fuel system, oil line, and brake fluid routing in custom engine builds and high-performance vehicle modifications. This adapter bridges metric banjo-style connections to AN (Army-Navy) standard plumbing, making it essential for engine swaps, fuel system upgrades, and turbocharger installations where thread standards may differ.

Manufactured from aerospace-grade aluminum, the banjo adapter features a precisely machined male bolt thread of M12x1.25, converting it to -4AN (1/4-inch AN) port sizing for compatibility with aftermarket hoses, filters, and manifolds. The compact 3.54-inch length and lightweight 0.04-pound profile minimize installation footprint in tight engine bays while maintaining structural integrity under pressure and thermal cycling.

This adapter is particularly beneficial for those fabricating custom fuel rails or integrating remote oil filter setups. It is designed to work with various fluids, including fuel, oil, coolant, and brake fluid, ensuring a reliable connection for high-performance applications.
