Zinc Plated Engine Lubrication Return Pipe DZ95319470313 Pre-Shaped Coiled Steel Tubing For Commercial Vehicle Turbo Oil Drain

Product Description

This oil return steel pipe assembly marked OE number DZ95319470313 serves as the dedicated oil drain pipeline for heavy-duty truck turbochargers. It guides lubricating oil flowing out of the turbo bearing housing back to the engine oil pan to realize circulating lubrication of the turbo system. The pipe adopts integrated CNC bending forming with multi-section spiral coil buffer structure, which can absorb engine vibration and thermal expansion deformation effectively to avoid pipe cracking and oil leakage. The one-piece banjo bolt joint at one end perfectly matches the turbo oil outlet interface, and the straight tube end connects tightly with the engine oil pan, fully consistent with the original vehicle pipeline layout for direct installation without secondary bending or cutting.

Key Product Advantages

• Seamless high-strength steel tube with full zinc plating anti-corrosion treatment, resisting engine high temperature, oil corrosion and muddy road rust for long service life.
• Multiple spiral coil buffer sections built into the pipeline, excellent shock absorption performance to eliminate metal fatigue fracture caused by long-term engine vibration.
• Precision one-time bending molding, consistent overall length and bending angle with factory original pipeline, no on-site reshaping required during maintenance replacement.
• Integrated banjo ball head connector at one end, smooth inner flow channel to ensure unobstructed oil return and prevent turbo oil accumulation leading to oil burning.
• Uniform wall thickness of steel pipe, strong pressure resistance, no swelling or rupture under high engine operating temperature and oil pressure.
