16AN to 12AN O-Ring Port Adapter Black Male Male

The REDHORSE PERFORMANCE 16AN to 12AN O-Ring Port Adapter in black anodized aluminum is a straight male-to-male fitting designed to bridge different AN port sizes in high-pressure fluid systems. This 920 Series adapter enables seamless integration when downsizing from 16 AN to 12 AN ports, making it essential for custom hydraulic, fuel, and coolant line configurations in performance vehicles, race cars, and industrial equipment.

Constructed from lightweight aluminum and finished in durable black anodize, this adapter resists corrosion and maintains structural integrity under demanding pressure cycling. The O-ring port design ensures reliable fluid-tight sealing without requiring additional sealant tape, while the straight flow path minimizes turbulence and pressure loss across the connection. At 0.21 lbs, the compact form factor (3.8 x 1.55 x 5.25 inches) fits tight engine bays and complex system layouts without adding unnecessary weight to the installation.

This adapter serves custom fabricators, performance shops, and enthusiasts who need flexible port-matching options when building or modifying fluid delivery systems. Whether scaling down line sizes for remote coolers, secondary fuel rails, or bypass circuits, the 920 Series adapter delivers the precise sizing control required for optimized flow management. The male-to-male configuration allows stacking multiple adapters or inline integration without requiring hose segments.

REDHORSE Performance is recognized for precision-engineered fluid system components that meet automotive and motorsports standards. This 16AN to 12AN adapter is sold as a single unit and is compatible with any system using standard AN port threads and O-ring seal methodology.
