The Fan Pilot Adapter 5/8in ID 3/4in OD 1/2in Long from Gorsuch Performance Solutions is a precision hose coupling engineered for cooling system integration in modified and high-performance vehicles. This compact adapter bridges different diameter cooling lines, enabling seamless fan shroud assembly, auxiliary cooling loop installation, or OEM-to-aftermarket radiator transitions. Whether you're building a custom cooling system for an engine swap, upgrading to a larger radiator, or integrating electric fans into an existing chassis, this adapter delivers the versatile connection point your project demands.
Manufactured to exacting tolerances, the Fan Pilot Adapter features a 5/8-inch inner diameter (ID) inlet and a 3/4-inch outer diameter (OD) outlet with a compact 1/2-inch length, allowing installation in tight engine bay spaces without compromising flow or structural integrity. The stepped design accommodates standard hose barbs or quick-disconnect couplings commonly found in modern cooling system configurations. Its lightweight construction—just 0.025 lbs—means zero parasitic weight penalty, while the precision bore geometry ensures turbulent-free fluid transitions that minimize cavitation and pressure drop during high-RPM operation.
Mechanics, engine builders, and fabricators rely on this adapter when custom-routing cooling lines during LS swaps, fuel cell conversions, or complete cooling system redesigns. It's ideal for applications requiring stepped hose connections without valve bodies or flow restrictors—perfect for pilots, overflow tanks, or auxiliary coolant reservoirs. Verify your hose ID/OD specifications before ordering; this adapter assumes standard 5/8in and 3/4in hose compatibility and should be paired with appropriate clamps or fittings per your system design. Made by Gorsuch Performance Solutions, a trusted name in precision automotive adapters and performance components.
