High-Precision Filtration & Leak-Proof Design

This oil-water separator assembly (OE:1125005-HR031) adheres to Dongfeng’s genuine manufacturing standards, featuring a multi-layer filter element (achieves 99.5% water separation efficiency) and high-density aluminum alloy body. The integrated leak-proof connectors adopt precision threading, ensuring zero fuel leakage even under 1.2MPa pressure—unlike aftermarket assemblies with loose seals. The anti-corrosion plastic connectors resist fuel erosion and road moisture, extending service life in high-humidity or coastal transport scenarios. Its optimized flow design maintains stable fuel supply, avoiding engine power loss during long-haul operations.

Fuel System Protection & Aftermarket Part Flaws

It is 100% compatible with Dongfeng KL’s fuel system (cross-check OE 1125005-HR031 for fitment). The assembly solves critical pain points for fleet operators: generic separators with low filtration efficiency (allowing water to enter the engine), leaky connectors (causing fuel waste and fire risks), and fragile materials (cracking under vibration). It reduces engine maintenance costs by 65% for fleets, preventing costly damage to injectors and cylinder liners caused by water-contaminated fuel. This ensures Dongfeng KL trucks stay operational and avoid unplanned downtime.

Factory-Certified Quality & Proven Durability

As a key fuel system component, this assembly meets GB/T 25984-2010 automotive fuel filter standards (third-party verified). Fleet test data shows it maintains 99% filtration efficiency after 10,000+ hours of operation, with no seal degradation. The aluminum alloy body withstands -40℃ to 80℃ temperature extremes, adapting to cold plateaus and high-temperature deserts. Each unit undergoes strict pressure testing and quality inspection before leaving the factory, marked with the official Dongfeng genuine part logo and OE number for full traceability and authenticity.
