Female 90 Degree Union A dapter; Size: -6AN

The Female 90 Degree Union Adapter in -6AN size is a precision hydraulic and pneumatic fitting engineered for applications requiring directional flow changes in high-pressure systems. Manufactured by Vibrant Performance, this adapter connects two -6AN female ports at a 90-degree angle, making it essential for custom fluid and coolant line routing in motorsports, industrial equipment, and specialized mechanical assemblies. The compact design allows installers to navigate tight engine bays and equipment spaces where straight connections are impractical.

Constructed from lightweight aluminum and finished with black anodizing, this fitting delivers corrosion resistance and durability in demanding environments. The -6AN designation indicates a nominal ID of 3/8 inch, a standard bore size for moderate to high-flow applications in racing fuel systems, oil cooling circuits, and transmission lines. Black anodized aluminum provides superior protection against oxidation while maintaining minimal weight—critical in competitive motorsports where every gram impacts performance. The 90-degree union design allows two separate hoses or lines to join at right angles, eliminating the need for multiple adapters and reducing potential leak points in complex plumbing configurations.

This adapter benefits professional mechanics, engine builders, and enthusiasts fabricating custom cooling, fuel, and hydraulic systems where -6AN fittings are standard. It pairs seamlessly with Vibrant Performance hose assemblies and compatible -6AN male fittings, enabling flexible system design without complex welding or bending. Installation requires hand-tightening with an appropriate wrench to specification; thread sealant tape (PTFE) is recommended for leak-free operation. For racing applications, custom hot rod builds, and industrial fluid transfer systems, this female-to-female union adapter delivers reliability and allows precise routing in space-constrained configurations.
