-6AN Female Swivel x 3/8in Barb Fitting

The -6AN Female Swivel x 3/8in Barb Fitting from DERALE (MPN 98200) is a precision hose adapter engineered for high-performance cooling, fuel, and fluid transfer systems. This fitting bridges AN (Army-Navy) standard female connections to 3/8-inch barbed hose, making it essential for custom hydraulic setups, automotive cooling loops, and aftermarket fuel system installations. The swivel design accommodates misaligned hose runs without inducing stress, a critical feature in tight engine bays or complex plumbing configurations where rigid connections would cause vibration-induced leaks or fitting failure.

Constructed from black anodized aluminum, this fitting delivers durability and corrosion resistance while maintaining the lightweight profile demanded in performance applications. The 6AN female port accepts standard AN-size hose adapters and bulkhead fittings, while the 3/8-inch barb design creates a mechanical lock with barbed hose, eliminating the need for secondary clamps in many installations—though industry best practice recommends hose clamps for vibration-prone environments. The swivel ball joint allows up to 360 degrees of rotational freedom, simplifying assembly and reducing strain on both the fitting and connected hose during thermal expansion and system pressure cycling.

This fitting serves enthusiasts building custom radiator systems, transmission coolers, intercooler setups, and fuel system upgrades where OEM hose routing cannot accommodate modern components. It is compatible with any -6AN female bulkhead, port, or hose end fitting, and pairs seamlessly with 3/8-inch braided or rubber hose rated for your system's operating pressure and temperature. Installation requires cutting hose to length and sliding it over the barb until it seats; the swivel connection should be hand-tightened snugly, then verified for leaks under system pressure. Ideal for street cars, race vehicles, and marine applications where reliable, vibration-tolerant connections are non-negotiable.
