Female 45 Degree Union A dapter; Size: -10AN

The Female 45 Degree Union Adapter in -10AN size from Vibrant Performance is a critical component for custom hydraulic and fuel line systems where space constraints or installation geometry demands an angled connection. This adapter serves technicians, fabricators, and performance enthusiasts who need to redirect fluid flow at 45 degrees while maintaining a secure, leak-free union between two female 10 AN ports. The 45-degree angle eliminates the need for multiple fittings and reduces complexity in tight engine bays or chassis configurations.

Constructed from aluminum and finished in black anodize, this union adapter combines lightweight durability with corrosion resistance essential for both street and race applications. The black anodized coating protects the aluminum from oxidation while providing a professional appearance that integrates seamlessly into modern custom builds. The -10AN designation refers to the industry-standard AN fitting size, which uses a 9/16-inch hose ID and is rated for high-pressure fluid transfer in fuel injection, cooling, and hydraulic systems. The compact design—measuring just 3.5 x 1.2 x 3.8 inches and weighing only 0.1 lbs—ensures minimal clearance interference during installation.

Engine builders, custom fabricators, and tuning shops rely on Vibrant Performance adapters to create efficient, compact plumbing layouts in racing engines, turbo systems, and fuel-injected conversions. The 45-degree angled configuration is ideal for situations where straight unions cannot be accommodated due to header clearance, intake manifold positioning, or intercooler placement. This adapter pairs directly with -10AN hose, fittings, and distribution blocks, making it an essential tool for anyone constructing or modifying high-performance fuel and cooling systems where every millimeter of space counts.
