FAW Truck Parts-1003016-M30-0000 Copper nozzle sleeve

Description

This copper nozzle sleeve is a precision sealing component installed on the cylinder head of heavy truck engines. It is positioned between the fuel injector and cylinder head, playing the role of heat insulation, sealing and heat conduction. It prevents high-temperature gas leakage and isolates heat to protect the injector assembly. Made of high-purity copper material, it has excellent thermal conductivity, plasticity and sealing performance. It can maintain stable sealing effect under high temperature and frequent thermal cycling. Each nozzle sleeve undergoes dimensional inspection and sealing test before delivery. It solves problems such as gas blow-by, injector carbon deposition and engine power reduction caused by damaged nozzle sleeve, serving as an essential replacement part for engine cylinder head maintenance.
