Extended Inline Filler Neck 1.50 Into 1.50

The Extended Inline Filler Neck 1.50 Into 1.50 is a critical cooling system component designed for custom plumbing configurations where a standard radiator fill point is inaccessible or insufficient. This Moroso engineered solution allows users to relocate the radiator cap to a higher or more convenient point in the cooling loop to ensure proper air bleeding and system filling. It is particularly valuable for performance vehicles, race cars, or engine swaps where space constraints dictate non-traditional radiator placement. By moving the fill point to the highest spot in the system, you can effectively prevent overheating issues caused by trapped air.

Constructed from high-quality natural aluminum, this filler neck features a robust hose-mount design that fits 1.5-inch diameter hoses on both the inlet and outlet sides. The unit includes a 1/8-inch NPT hose barb port, which is essential for connecting overflow tanks or pressure relief lines to maintain cooling system integrity under high-heat conditions. Its extended design provides additional height to help eliminate air pockets within the engine block and radiator, improving overall thermal efficiency. The smooth internal bore ensures that coolant flow remains unrestricted, preventing cavitation and maintaining consistent pressure throughout the loop.

This specific model is intended for professional installation in cooling systems utilizing standard 1.5-inch radiator hoses and is compatible with most standard radiator caps. The lightweight aluminum housing ensures that no significant stress is added to the plumbing while providing a durable, corrosion-resistant service life. Whether you are looking for specifications for a custom build or ready to buy, the Extended Inline Filler Neck 1.50 Into 1.50 offers a reliable solution for optimizing fluid management in demanding automotive environments. It provides a clean, professional finish to any engine bay while solving complex plumbing challenges faced by enthusiasts and racers alike.
