The AFCO Racing Products Inlet Fitting Radiator 16AN (part number 80072) is a precision aluminum adapter designed to manage coolant flow in high-performance marine and racing cooling systems. This straight-configuration fitting transitions from a 20 AN male O-ring connection to a 16 AN male port, enabling flexible plumbing layouts without compromise to flow integrity. Built from aluminum and finished in natural anodize, the fitting delivers the durability and corrosion resistance demanded by serious boaters and offshore anglers who run aggressive cooling systems in salt-water environments.
Weighing just 0.24 lbs and measuring 3.8 × 2.05 × 6.3 inches, this compact adapter integrates seamlessly into tight engine compartments without adding bulk. The 20 AN to 16 AN step-down allows boaters to optimize hose sizing throughout their cooling circuit—larger diameter lines upstream where flow volume is highest, smaller diameter lines downstream where space constraints or cost savings matter. The O-ring face seal provides reliable, leak-free performance under sustained pressure cycles, critical for preventing coolant loss during extended offshore runs or high-RPM operations.
This fitting is essential for weekend fishermen upgrading stock cooling systems and serious tournament competitors who demand custom water-management solutions. Whether you're plumbing a new high-output engine block, replacing a corroded original fitting, or fine-tuning an existing system for better thermal management, the AFCO 16AN inlet radiator fitting provides the precision connection point your system requires. Aluminum construction keeps weight down—a priority in performance boating where every pound affects fuel efficiency and speed.
TacticalSurplusUSA stocks AFCO Racing Products fittings and adapters for marine builders and engine builders who prioritize reliability and thermal performance. This individual adapter is backed by AFCO's reputation for precision engineering and fits into professional cooling system assemblies across the marine racing and high-performance boating sector.
