Water Neck Housing Ford w/ -16an Fitting

The Water Neck Housing Ford w/ -16AN Fitting is a precision aluminum coolant distribution component designed for small-block Ford engine builders and performance enthusiasts. This 35-degree water neck serves as the critical junction point where the upper radiator hose connects to the engine block, effectively managing coolant flow under high-pressure conditions.

Manufactured by U-B Machine from high-quality billet aluminum and finished in blue anodize, this water neck housing ensures durability and corrosion resistance in high-heat engine environments. The -16AN male fitting accommodates industry-standard braided hose or hard-line cooling systems, providing flexibility in custom plumbing layouts. The 35-degree angle optimizes hose routing in tight engine bays while minimizing stress on connection points.

Small-block Ford owners—from 221 to 351 cubic-inch platforms—benefit most from this bolt-on water neck when transitioning to aftermarket cooling systems or custom engine bays. Its compact dimensions ensure fitment in space-constrained installations without interference with accessory brackets or valve covers.
