Yuchai FC700-1003176 Injector Copper Bushing

This injector copper bushing serves as a critical sealing interface between the fuel injector and cylinder head in Yuchai diesel engines. Manufactured from high thermal conductivity copper alloy via precision casting process, it ensures optimal heat transfer from the injector nozzle to the cooling system while maintaining fuel sealing integrity under high pressure combustion cycles. Designed as direct replacement for Yuchai part numbers FC700-1003176 and T9000-1003176, this component restores injector seating geometry and prevents combustion gas leakage into the fuel system. Compatible with Yuchai YC4F four-cylinder and YC6T six-cylinder engine series commonly equipped in Dongfeng, Sinotruk, and JAC heavy duty truck platforms.
