Cooling System Hose Fill

The Northern Radiator Cooling System Hose Fill (Model Z12006) is a hose-mount filler neck adapter engineered for seamless integration into cooling systems requiring 1-1/2 inch diameter hose connections. Constructed from aluminum and finished in natural metal, this component bridges two matching hose ports while providing convenient access for system filling, bleeding, and coolant maintenance without requiring permanent modifications to the radiator or header tank.

The 1-1/2 inch hose-to-hose configuration accommodates standard automotive and industrial cooling system tubing, making this fill adapter compatible with vehicles and equipment using this common hose diameter specification. Aluminum construction provides a balance of durability and corrosion resistance, while the natural finish integrates cleanly into engine bay or system installations. The compact dimensions (6.1 x 2.2 x 9 inches) and lightweight profile (0.4 lbs) ensure minimal footprint and easy installation without adding significant mass to the cooling circuit.

This filler neck adapter is ideal for custom cooling system builds, restoration projects, and aftermarket radiator installations where OEM fill provisions are absent or incompatible with modern hose sizes. Technicians and builders working on classic automotive restorations, performance cooling upgrades, or industrial equipment maintenance will find this component essential for systems transitioning to standardized 1-1/2 inch hose diameters. The direct hose-mount design eliminates the need for threaded ports or tank-specific adapters, providing flexibility in placement and routing within tight engine compartments.
