Pre Bent High Pressure Steel Oil Pipe Unit DZ96319470913 To Solve Fuel Leakage And Oil Supply Insufficient Malfunctions

• This DZ96319470913 oil pressing pipe is a dedicated high pressure fuel delivery hard line for Shaanxi M3000 8x4 trucks equipped with WP9H 300 diesel engines
• The pipe adopts thick seamless steel tube with precise CNC bending to match original vehicle chassis pipeline routing layout
• Both ends are equipped with standard metal thread connectors sealed with anti leakage red sealing gaskets for stable fuel circulation
• The outer surface is treated with anti rust black coating to adapt complex muddy and saline outdoor driving environments
• All pipe length bending angles and thread connector specifications strictly follow OEM production standards for direct vehicle matching

• Thick seamless steel tube structure withstands long term engine high fuel pressure without pipe expansion or bursting risks
• Accurate one time CNC bending avoids forced installation deformation and keeps smooth internal fuel flow without flow resistance increase
• Integrated metal thread joints with red sealing washers effectively block fuel leakage at connection points under vehicle vibration conditions
• Anti rust black outer coating resists rain mud and road salt erosion to extend service life of the fuel pipeline assembly
• Smooth inner tube wall reduces fuel flow resistance to guarantee stable continuous oil supply for WP9H 300 engine full load operation

• Every finished oil pipe completes high pressure hydraulic sealing test to eliminate internal pipe cracks and joint leakage hidden dangers
• Full dimensional inspection verifies all bending shapes and total length to fit original chassis pipeline installation positions perfectly
• Salt spray anti corrosion aging test confirms long term rust prevention performance under harsh all weather driving environments
• All seamless steel tube and metal joint raw materials meet heavy truck high pressure fuel pipeline industry quality standards
• Each oil pressing pipe assembly is marked with unique part number to realize complete traceability of production and inspection records
