Female Union Adapter 45 45 Degree -16AN

The Female Union Adapter 45 Degree -16AN from Vibrant Performance is a critical hydraulic fitting for high-performance fuel, oil, and coolant systems in modified and racing vehicles. Whether you're building a custom fuel rail, upgrading to an external oil cooler, or fabricating a complex plumbing layout, this adapter provides the precise directional change and secure connection your system demands. Mechanics and fabricators rely on these union adapters to create leak-free, professional-grade installations in turbocharged engines, LS swaps, and dedicated race builds.

This 45-degree female union adapter is engineered with a -16AN port size, allowing smooth fluid transitions at a 45-degree angle while maintaining full flow capacity and structural integrity under pressure. The female threaded design accepts male -16AN fittings, hose ends, and bulkhead connectors, making it versatile for both braided hose runs and hardline applications. Manufactured from aircraft-quality aluminum or ductile iron, these adapters withstand vibration, thermal cycling, and the demands of forced-induction and high-RPM environments without degradation, ensuring your system stays sealed and performs reliably lap after lap.

Serious engine builders, turbo kit installers, and fuel system fabricators choose Vibrant Performance adapters for their precision tolerances and proven track record in competition vehicles. Use this fitting wherever you need to redirect flow while saving space and maintaining consistent system pressure—ideal for tight engine bays, custom intercooler lines, fuel cell installations, and prototype builds. Installation is straightforward: thread onto -16AN male fittings with appropriate thread sealant, and torque according to your system's specifications. Compatible with all standard -16AN hydraulic components, this adapter is an indispensable part of any modular, custom, or high-flow plumbing strategy.
