16AN to 16AN O-Ring Port Adapter Black Male Male

The 16AN to 16AN O-Ring Port Adapter Black Male Male from REDHORSE PERFORMANCE is a precision hydraulic and fuel line fitting designed for high-performance automotive, aircraft, and industrial fluid transfer systems. This straight adapter connects two 16 AN male ports with a reliable o-ring seal, eliminating the need for separate hose sections and reducing potential leak points. Engineered for applications requiring secure, leak-free connections in demanding environments, this adapter is essential for builders and technicians working with fuel injection systems, power steering circuits, and pressurized fluid delivery networks.

Manufactured from aluminum and finished in black anodize, the 16AN to 16AN O-Ring Port Adapter features a straight configuration that allows direct port-to-port connection without bends or offsets. The o-ring seal design provides superior sealing performance compared to thread-only connections, preventing fluid loss under vibration and thermal cycling common in high-performance applications. The black anodized finish offers corrosion resistance and durability while maintaining a professional appearance on custom builds. Compact dimensions (3.8 x 1.55 x 5.25 inches) and minimal weight (0.22 lbs) ensure this fitting integrates seamlessly into tight engine bays and complex plumbing layouts without adding unnecessary bulk.

This adapter is ideal for custom fuel system builders, race engine builders, and restoration specialists who demand reliability in high-pressure circuits. The 16 AN port size accommodates substantial flow rates, making it suitable for turbocharged and supercharged engine fuel delivery, nitrous oxide systems, and complex hydraulic networks. Installation requires standard AN wrench sizing and compatibility with existing 16 AN male fittings on both sides; the o-ring seal means proper torque specifications must be followed to ensure optimal performance. Whether upgrading OEM systems or designing custom fuel cells and cooling circuits, this REDHORSE adapter provides the professional-grade connection integrity expected by serious automotive enthusiasts.
