Ford Radiator Adapter Fitting Kit

The Ford Radiator Adapter Fitting Kit by DERALE is a critical cooling system component designed for mechanics and enthusiasts performing custom radiator installations, engine swaps, or hose routing modifications. This brass adapter set solves a common problem when upgrading cooling systems or relocating radiators: mismatched OEM hose connections that don't align with aftermarket cores or custom fabrication requirements. Whether you're upgrading to a high-performance radiator for improved heat rejection or reconfiguring coolant lines during an engine bay refresh, this fitting kit ensures proper hydraulic connections without costly custom fabrication or incompatible plumbing.

The kit features dual brass adapters combining 5/8-18 inch inverted flare threads with 3/8 inch hose barb outlets, allowing you to transition between inverted flare fuel or coolant line standards and standard barbed hose connections. Brass construction resists corrosion in coolant-rich environments and provides excellent thermal stability under engine bay temperatures, while the inverted flare design guarantees leak-free connections under system pressure. One adapter converts female inverted flare to hose barb; the complementary piece converts male inverted flare to hose barb—giving you flexibility to adapt both sides of a cooling circuit or fuel system modification without additional hardware sourcing.

This fitting kit is ideal for Ford radiator swaps, engine conversions, and custom cooling loops where OEM Ford inverted flare ports need to interface with modern silicone hose or barbed fittings. Installation requires basic hose clamp tools and standard SAE wrenches to seat the flare connections—no specialized equipment needed. The compact 0.09 lb weight and small footprint make these adapters suitable for tight engine bay spaces, and their universal male/female pairing ensures compatibility with most Ford coolant circuit configurations. Use this kit whenever you encounter mismatched radiator inlet or outlet threads during restoration, tuning, or performance cooling upgrades.
