#4 To 7/16 Banjo Steel Brake Adapter

The #4 to 7/16 Banjo Steel Brake Adapter (FCM2940) is a straight-fitting hydraulic adapter designed to connect AN-4 male ports to 7/16-inch banjo-style fittings. Built from steel with zinc oxide coating, this adapter pair delivers the corrosion resistance and durability required in high-vibration environments where brake lines, fuel systems, and fluid transfer lines demand reliable, leak-free connections. The straight configuration eliminates unnecessary bends, reducing pressure drop and simplifying installation on custom brake setups, off-road recovery winches, and heavy-duty hydraulic applications.

The AN-4 male thread (1/4-inch NPT equivalent) interfaces with the banjo bolt pattern standard on aftermarket and OEM brake calipers, master cylinders, and distribution blocks. Zinc oxide plating protects against rust and oxidation in humid conditions, salt air, and high-moisture environments common to coastal, offshore, and wet-climate operations. At 0.14 pounds per pair, these adapters impose minimal weight penalty while maintaining full structural integrity under peak brake pressure cycles. The compact footprint (2.35 x 1.05 x 3.75 inches) fits tight engine bays and custom fabrication spaces where standard elbow adapters create clearance conflicts.

This adapter pair serves custom brake builds, emergency response vehicles, high-performance off-road platforms, and hydraulic system modifications where AN fittings interface with banjo-port components. Users upgrading from OEM to aftermarket brake lines, installing remote brake cylinders, or adapting incompatible fluid system architectures depend on precision adapters to maintain system reliability under sustained pressure and thermal cycling. The steel construction resists vibration-induced loosening and withstands repeated pressure fluctuations without creep or fatigue failure.
