330103903 Air Inlet Connector XCMG XDE130 Electric driving dump truck spare parts

The 330103903 air intake connector is an original equipment manufacturer (OEM) product from XCMG, specifically designed for XCMG excavators (such as the XE600D) and loaders. It addresses the pain points of ordinary connectors, such as air leakage, high intake resistance, and susceptibility to corrosion. Widely used in engine intake pipe connections, it is a core component in maintenance and repair. The product complies with XCMG’s OEM standards and GB/T 14383 standards, using high-quality carbon steel as the base material. Manufactured through CNC milling and precision tapping processes, its conical sealing structure is suitable for high-temperature, high-dust, and high-frequency vibration conditions, ensuring perfect compatibility with original equipment and meeting XCMG’s supply chain digitalization requirements.
