#16 90 Degree Hose End Swivel

The #16 90 Degree Hose End Swivel by AEROQUIP (MPN FCM4036) is a precision-engineered hydraulic fitting designed for custom automotive cooling, fuel, and power steering applications where space is tight or hose routing demands a sharp directional change. Built for serious builders and mechanics who refuse to compromise on fluid system integrity, this 16 AN swivel connector eliminates the need for separate elbows and adapters, reducing leak points and weight in high-performance engine bays, race cars, and modified street vehicles. Whether you're building a custom fuel system, upgrading coolant lines on a turbocharged engine, or rerouting hydraulic hoses in a hot rod chassis, this fitting delivers the directional flexibility that professional installations require.

Constructed from aerospace-grade aluminum and finished in vibrant blue and red anodized coating, the #16 90 Degree Hose End Swivel offers both durability and corrosion resistance in harsh engine environments. The 90-degree swivel design allows full hose articulation without kinking, while the 16 AN male hose connection mates to 16 AN female swivel ports on manifolds, radiators, and custom fabricated components. AEROQUIP's engineering ensures tight tolerances and smooth internal passages that maintain flow rates and system pressure without turbulence or restriction. At just 0.45 pounds, this fitting adds minimal weight while providing the structural integrity needed for fuel injection systems, oil cooler circuits, and transmission cooler setups that operate under sustained pressure and temperature cycling.

This swivel fitting is ideal for fabricators, restoration specialists, and engine builders who demand OEM-equivalent or better performance in custom hydraulic applications. It pairs seamlessly with 16 AN hose (SAE J518 standard) and works across cooling systems, fuel delivery, power steering, and transmission fluid circuits in American muscle cars, imports, drag cars, and street performance builds. Installation requires basic AN fitting knowledge—hand-tighten then use a wrench on the hose end hex while holding the swivel body stationary to prevent damage. Keep a spare on hand for future builds; AEROQUIP's track record in racing and aerospace applications makes this a trusted upgrade for anyone serious about system reliability.
