Female Union Adapter 45 46 Degree -20AN

The Female Union Adapter 45 46 Degree -20AN by Vibrant Performance is a precision hose fitting engineered for high-performance fuel, oil, and coolant systems where space constraints demand compact, angled connections. This adapter bridges hydraulic or pneumatic lines at a 45–46-degree angle, allowing you to navigate tight engine bays, transmission tunnels, and chassis configurations without kinks, sharp bends, or stress fractures that compromise flow integrity. Whether you're building a street-strip engine, upgrading a fuel system on a turbocharged platform, or retrofitting cooling lines on a custom swap, this union adapter solves the geometry problem where straight or 90-degree fittings won't fit.

Constructed from aluminum or stainless steel with a female -20AN thread port, the Female Union Adapter 45 46 Degree -20AN accommodates standard -20AN male hose ends and hard-line fittings without leakage or vibration-induced loosening. The 45–46-degree angle geometry reduces turbulence and pressure drop compared to multiple 90-degree bends, maintaining system efficiency across fuel rail pressures, coolant circulation, and brake or power-steering circuits. Vibrant Performance's anodized finish resists corrosion and thermal cycling, critical in engine compartments where condensation and heat cycling degrade inferior fittings. Weighing just 0.33 lbs, it adds negligible mass while delivering OEM-grade durability and leak-proof sealing through precision machining and controlled tolerances.

This adapter is indispensable for chassis engineers, fabricators, and performance builders tackling engine bay layout challenges on supercharged, turbocharged, or LS-swap platforms. Installation requires standard -20AN hose crimping tools and proper thread-sealant protocol; compatibility spans any system running -20AN AN fittings, including Fuel Injector Clinic, Aeromotive, and OEM fuel rails. Pair it with matching -20AN hose, barbed adapters, and swaged fittings to build a complete, vibration-resistant fluid delivery network that maintains pressure integrity under boost and sustained RPM. Available for immediate purchase, it's a must-have for anyone serious about reliability in custom or modified powerplant configurations.
