#4 Female Swivel Connect Black

The FRAGOLA #4 Female Swivel Connect Black (part number 496104-BL) is a straight adapter fitting engineered for high-pressure hydraulic and fluid transfer applications where secure, leak-free connections are critical. This aluminum swivel connector links two 4 AN female swivel ports in a direct-flow configuration, making it essential for fuel systems, cooling loops, transmission lines, and brake assemblies in performance vehicles, marine engines, and industrial hydraulic systems.

Constructed from lightweight aluminum with black anodized finish, this female-to-female adapter resists corrosion and oxidation while maintaining compatibility with standard AN hose fittings. The swivel design at each end permits angle adjustment during installation, reducing stress on hose assemblies and extending system life. Weighing just 0.03 lbs and measuring 4.1 inches in length, the fitting integrates into tight engine bays and compact plumbing layouts without bulk. The 4 AN port size accommodates high-flow applications while maintaining the velocity and pressure characteristics required in racing fuel injection systems, turbocharged cooling circuits, and heavy-duty hydraulic controls.

This connector suits technicians assembling custom fuel rails, rebuilding transmission cooling systems, and modifying hydraulic brake lines where standardized AN fittings are the industry norm. Buyers sourcing FRAGOLA adapters appreciate the brand's precision manufacturing and long service record in motorsports, aviation, and OEM hydraulic supply. The black anodized finish matches modern engine bay aesthetics while providing a durable barrier against moisture and chemical exposure typical in high-temperature engine compartments and marine environments.
