Swivel Union Female -6 to Female -8

The Swivel Union Female -6 to Female -8 from ALLSTAR PERFORMANCE is a precision hydraulic and pneumatic adapter fitting designed to connect AN-spec hose lines of different sizes with complete rotational freedom. This straight-port adapter is essential for race teams, fabricators, and performance enthusiasts who need flexible plumbing configurations in tight engine bays or complex fluid transfer systems. The swivel design eliminates the need for angled approaches during installation and maintenance, reducing installation time and preventing accidental hose kinking.

Constructed from lightweight aluminum and finished in black anodize for corrosion resistance, this adapter features a female -6 AN swivel port on one end and a female -8 AN swivel port on the other, allowing seamless integration between different circuit requirements. The 360-degree swivel action on both ends permits hose lines to rotate independently without torque transfer to the fitting body, protecting seal integrity and extending system life. Black anodized aluminum provides excellent durability in high-temperature environments while maintaining minimal weight—critical in competitive racing and aerospace applications where every fraction of a pound matters.

This adapter is ideal for custom hydraulic systems, fuel distribution networks, coolant circuits, and pneumatic applications requiring mixed AN line sizes. Its compact footprint (2.1 x 1.2 x 4.1 inches) makes it suitable for space-constrained installations common in engine modifications and race car builds. The female-to-female configuration works seamlessly with standard -6 and -8 AN hose assemblies and fittings, making it a versatile solution for both new fabrication projects and system modifications. Installation requires only hand-tightening of hose connections—no special tools needed.
