Female To Male Flare FEM-4 TO MALE-6

The Female To Male Flare FEM-4 TO MALE-6 is a precision hydraulic and fuel system adapter designed for serious boaters, anglers, and high-performance watercraft operators who demand reliability under demanding marine conditions. This straight-thread flare fitting bridges the gap between 4 AN female swivel connections and 6 AN male ports, making it an essential component for custom fuel line routing, hydraulic trim systems, or ballast plumbing on center consoles, offshore boats, and performance skiffs. Whether you're upgrading fuel delivery on a twin-engine bass boat or reconfiguring hydraulic lines on a commercial fishing vessel, this adapter ensures secure, leak-free connections where standard off-the-shelf solutions fall short.

Constructed from aluminum and finished in blue anodize, the Female To Male Flare FEM-4 TO MALE-6 resists saltwater corrosion while maintaining excellent strength-to-weight characteristics critical for marine plumbing systems. The swivel female end allows for easy hand-tightening without wrench damage to surrounding hoses, while the male flare end delivers a dependable seal through industry-standard 37-degree AN flare geometry. Aluminum construction keeps overall system weight minimal—essential on performance boats where every pound affects fuel efficiency and handling—while the anodized finish adds years of service life in harsh saltwater and brackish environments common to coastal fishing and offshore operations.

This fitting is ideal for professional and recreational boaters undertaking custom fuel system work, hydraulic upgrades, or troubleshooting plumbing mismatches on retrofit projects. Installation requires no special tools beyond a standard wrench on the male end; the swivel female connector accepts hose fittings hand-tight with no risk of thread cross-threading. Ensure proper flare compatibility (37-degree AN standard) on all mated components, and apply thread sealant rated for fuel or hydraulic fluid to prevent weeping under vibration and pressure cycling typical of marine engine compartments.
