Swivel Union Female -6 to Female -6

The Swivel Union Female -6 to Female -6 from ALLSTAR PERFORMANCE is a critical hydraulic and fuel line adapter designed for custom automotive builds, high-performance engine swaps, and precision fluid transfer systems. This fitting bridges two -6 AN (Anderson) female connections, making it essential for builders who need flexible routing options without compromising flow integrity. Whether you're assembling a custom fuel system, upgrading brake lines, or installing cooler circuits, this swivel union solves misalignment challenges that rigid fittings cannot address.

Constructed from lightweight aluminum with a durable black anodized finish, the Swivel Union Female -6 to Female -6 features a 360-degree rotating design that eliminates stress on hose assemblies and reduces vibration-induced leaks—a common failure point in aggressive street and race applications. The swivel mechanism allows hoses to rotate freely during installation and operation, preventing line twist and the microfractures that lead to catastrophic failures under pressure cycling. The -6 AN specification delivers reliable performance in high-flow applications while maintaining compatibility with industry-standard hose barbs and fittings used across domestic and import platforms.

Mechanics and fabricators rely on this adapter for fuel injection conversions, turbo coolant lines, transmission cooler installations, and custom plumbing where hose routing demands flexibility. The compact 2.45 x 1.25 x 4-inch footprint fits tight engine bays and chassis tunnels without requiring extensive modifications to surrounding components. Installation is straightforward—simply thread both female connections into your AN-compatible ports and secure with appropriate sealing tape or thread sealant. This union is rated for continuous use in pressurized systems and suits both street applications and controlled track environments where reliability under thermal stress is non-negotiable.
