Adapter Fittings -4 to 7/16-20 10pk

The ALLSTAR PERFORMANCE Adapter Fittings -4 to 7/16-20 10-pack (ALL50032-10) is a precision straight adapter designed to connect AN-sized fluid lines to 7/16-20 threaded ports. This set of 10 steel fittings features zinc oxide plating for corrosion resistance and uses O-ring sealing to prevent fluid leakage at connection points. The straight configuration eliminates offset flow paths, making these adapters ideal for systems where direct line routing is required without elbows or angled fittings.

Each adapter in this 10-pack handles the transition from 4 AN male threads to 7/16-20 male O-ring ports, a common configuration in high-pressure fuel and fluid systems. The zinc oxide finish protects against oxidation in both wet and dry environments, while the O-ring seal design eliminates the need for thread sealant tape on the connection point. Steel construction provides the durability required for vibration-resistant applications where fittings must maintain pressure integrity under repeated thermal cycling.

This adapter set serves technicians and builders working on fuel delivery systems, hydraulic installations, and fluid transfer applications where AN line compatibility is essential. The 10-pack quantity is suited for system builders who need multiple connection points or spare inventory for maintenance and repair work. Whether installing a fuel system in a race vehicle, constructing a hydraulic assembly, or replacing worn fittings in an existing installation, having a ready supply of certified adapters ensures project continuity without delay.

AN-to-SAE adapter fittings are foundational components in custom fluid systems where different thread standards must interface. The -4 to 7/16-20 configuration bridges mid-size AN line systems with standard port threads found on many engines, transmissions, and aftermarket components. ALLSTAR PERFORMANCE's focus on precision hydraulic and fuel system components makes this 10-pack a practical choice for builders who demand reliability and repeatability across multiple installations.
