The Fan Pilot Adapter 5/8in ID 3/4in OD 1/2in Long from Gorsuch Performance Solutions is a precision hose coupling component designed for professional-grade engine cooling system modifications. This adapter serves as a critical bridge fitting in custom cooling loops, particularly for high-performance and modified vehicles where OEM hose routing requires reconfiguration. Whether you're installing an aftermarket water pump, upgrading to larger radiator capacity, or fabricating a custom coolant bypass circuit, this adapter ensures leak-free connections between varying hose diameters and hard-line tubing.
Engineered with a 5/8-inch inner diameter (ID) and 3/4-inch outer diameter (OD) profile, this 1/2-inch-long adapter is precision-machined to deliver consistent barb engagement and barbed-hose grip. The stepped design accommodates smooth transitions between different hose sizes without turbulence or flow restriction—critical when managing high-volume coolant circulation in boost-cooled or supercharged applications. Gorsuch Performance Solutions manufactures this component to exacting tolerances, ensuring positive seating and resistance to vibration-induced loosening during sustained engine operation or thermal cycling.
This adapter is ideal for fabricators, performance shops, and experienced mechanics building custom cooling solutions for street rods, race engines, and modified trucks. Installation requires only standard hose clamps and basic hand tools; secure each end with double clamps to maximize holding power under boost or extreme temperature swings. The compact 0.025 lb weight and minimal footprint make it perfect for tight engine bay layouts where space is at a premium. Verify your existing hose sizes and hard-line fitting dimensions before ordering to ensure seamless integration into your cooling system upgrade.
