1.50in Hose Water Neck Fitting - Polished

The 1.50in Hose Water Neck Fitting – Polished by MEZIERE is a precision engineered adapter designed for high-performance cooling systems in custom automotive and engine builds. This water neck fitting serves as a critical junction point between your engine block and radiator hose, directing coolant flow with minimal turbulence and maximum reliability. Whether you're assembling a modified engine, restomod, or racing application, this adapter ensures proper coolant circulation and system integrity under demanding conditions.

Constructed from lightweight aluminum and finished in a polished surface, the 1.50in Hose Water Neck Fitting features a straight design with a 20 AN male O-ring port on one end and a 1.5-inch hose barb on the other. The O-ring seal provides a leak-free connection with AN-compatible fittings, while the barb end securely locks standard 1.5-inch diameter hose without clamps or additional fasteners. The polished finish not only enhances visual appeal in engine bays but also resists corrosion and simplifies maintenance, making it ideal for show builds and functional systems alike.

This fitting is essential for builders integrating aftermarket water pumps, aluminum radiators, or remote-mounted cooling components into small-block and big-block engines. The straight configuration accommodates tight engine compartments where angled adapters won't fit, while the 20 AN O-ring port ensures compatibility with modern stainless steel braided hose assemblies. Compact at just 0.22 lbs and measuring 4.6 x 2.15 x 5.4 inches, installation is straightforward—simply thread into your engine block's water neck port and attach your 1.5-inch hose to the barb end. Precision manufacturing by MEZIERE guarantees dimensional accuracy for leak-free operation across countless heat cycles.
