Male Adapter Fitting #6 x 16mm x 1.5 FI

The Male Adapter Fitting #6 x 16mm x 1.5 FI by FRAGOLA is a precision-engineered hydraulic adapter designed for fuel injection systems and high-pressure fluid transfer applications. This straight adapter bridges two different connection standards—a 6 AN male port and a 16mm x 1.50 male thread—making it an essential component for custom fuel system builds, performance engine swaps, and aftermarket fuel rail installations. Whether you're upgrading a classic hot rod fuel system or fine-tuning a modern performance engine, this adapter ensures reliable, leak-free connections between incompatible fittings.

Manufactured from lightweight aluminum and finished in blue anodized coating, the Male Adapter Fitting delivers both durability and corrosion resistance in demanding fuel system environments. The blue anodize not only provides aesthetic continuity with FRAGOLA's premium product line but also guards against oxidation and extends service life. The straight-port design eliminates unnecessary flow restrictions and turbulence, critical for maintaining fuel pressure stability and protecting sensitive fuel injectors from debris or pressure spikes. The 6 AN male fitting accommodates standard SAE J518 Code 61 hose and adapters, while the 16mm x 1.50 male thread accepts metric fuel rails and fuel manifolds commonly found in European and modern fuel injection platforms.

This adapter is ideal for technicians, engine builders, and automotive enthusiasts performing fuel system custom fabrication or component replacement. Installation is straightforward: thread the 16mm x 1.50 male end into the fuel rail or manifold port, and connect your 6 AN hose or fitting to the opposite end using appropriate AN wrenches. Ensure proper thread sealant or PTFE tape is used on the metric male thread to guarantee a fuel-tight seal. The compact 4.15-inch length and minimal weight (0.04 lbs) make it easy to integrate into tight engine bay layouts without adding bulk or strain to fuel lines.
