Inlet Fitting -16AN

The Inlet Fitting -16AN from PWR NORTH AMERICA is a precision hydraulic adapter designed for high-flow cooling system installations and custom automotive plumbing applications. This straight-configuration fitting transitions between 16 AN male and 20 AN male O-ring connections, making it essential for builders upgrading factory radiators to aftermarket units or installing auxiliary cooling circuits on turbocharged and supercharged engines. Whether you're fabricating a custom water cooling loop or integrating a secondary cooler into an existing system, this adapter bridges common line-size mismatches without compromising flow integrity or system pressure ratings.

Machined from aluminum and finished in natural bare metal, the Inlet Fitting -16AN leverages O-ring face seal (ORFS) design on both ports to ensure leak-free connections under sustained boost and thermal cycling. The straight-port geometry minimizes turbulence and pressure drop compared to 90-degree or 45-degree alternatives, preserving system efficiency in high-performance cooling applications. At just 0.12 lbs and compact 3.25 x 1.9 x 4-inch dimensions, installation fits tight engine bays without requiring extensive rerouting of existing hardline or hose runs. The aluminum construction resists corrosion in modern coolant environments while offering excellent thermal conductivity.

Mechanics and engine builders working with PWR radiators, C&R coolers, and aftermarket cooling manifolds will find this fitting indispensable for adapting to standard -16AN hose or braided stainless line. Compatible with most street and race cooling configurations running up to typical OEM and mild boost pressure limits, it's a critical component for anyone upgrading from factory cooling on turbocharged or high-displacement naturally aspirated platforms. Proper torque and AN-rated hose end fittings ensure lasting reliability and warranty coverage on your cooling system investment.
