Inline Coolant Hose Filler 1.50/1.50 Male

The Inline Coolant Hose Filler 1.50/1.50 Male from PRW Industries is a precision-engineered coolant system component designed for custom and high-performance engine builds where direct hose-to-hose connections are required. This filler neck serves as a bridge fitting in cooling circuits, allowing seamless integration between two 1.5-inch diameter hoses without the need for traditional threaded flanges or tank-mounted necks. It's ideal for builders working with non-standard cooling layouts, custom radiator configurations, or compact engine compartments where space constraints demand creative plumbing solutions.

Constructed from lightweight aluminum with a natural (unpainted) finish, this inline coolant hose filler features dual 1.50-inch male hose barb connections that provide secure, leak-resistant sealing when paired with appropriate hose clamps. The aluminum construction offers excellent corrosion resistance in coolant environments while minimizing overall system weight—a key consideration in performance and racing applications. The symmetrical male-to-male design ensures bidirectional compatibility, allowing installation in either orientation, and the smooth bore interior maintains unrestricted coolant flow critical for efficient heat transfer and system reliability.

This filler fitting is best suited for street rod builders, race car fabricators, and engine swap specialists who require custom coolant routing without factory tank assemblies. It's commonly used in small-block and big-block V8 conversions, vintage vehicle restorations with modern cooling systems, and competition engines where every component must be optimized for flow and weight. Compatibility is universal across any cooling system using 1.5-inch diameter hoses—simply slide onto the barbed ends and secure with stainless steel hose clamps rated for your operating pressure. Weighing just 0.47 pounds, it adds minimal mass while delivering the functional reliability serious builders demand.
