Dongfeng XInjiang oil pipe 3405042-T8M300Y for sale

Crafted with a multi-layer structure for maximum safety and durability, the oil pipe’s inner tube is made of nitrile butadiene rubber (NBR) — a material with excellent oil resistance (compatible with diesel, biodiesel B20, and lubricating oils) and high-pressure tolerance (sustaining constant working pressure up to 1.2MPa, with a burst pressure of 3.6MPa). The middle layer features a high-tensile polyester fiber braid (24 strands, 0.2mm diameter) that reinforces structural stability, preventing expansion or deformation under pressure spikes (e.g., during engine startup or heavy acceleration). The outer layer is a wear-resistant chloroprene rubber (CR) coating, which shields the pipe from abrasion by chassis components or road debris

To ensure zero fuel leakage — a critical safety requirement for heavy-duty trucks — the 3405042-T8M300Y oil pipe is equipped with two key sealing features. First, its threaded connectors are pre-coated with anaerobic thread sealant (Loctite 577, compliant with automotive standards), which cures to form a permanent seal against high-pressure fuel. Second, the quick-connect fittings (at the engine end) incorporate a double O-ring design (made of fluororubber FKM, resistant to oil and high temperatures) that creates a redundant seal, even if one O-ring wears over time. All connectors undergo 100% air pressure testing (at 2.0MPa for 5 minutes) before leaving the factory, ensuring no leakage

Designed to withstand extreme operating conditions, the oil pipe maintains optimal performance across a temperature range of -40°C to +120°C — suitable for Dongfeng Xinjiang trucks operating in cold northern China (e.g., Heilongjiang) or hot southern regions (e.g., Guangdong). The NBR inner tube resists fuel oxidation and hydrolysis, preventing rubber degradation even after long-term exposure to moisture (up to 95% relative humidity). Additionally, the outer CR layer is UV-resistant (passing 1000-hour xenon lamp aging tests without cracking) and chemical-resistant to road salt, diesel additives, and industrial solvents — ensuring a service life of over 300,000 kilometers under normal use

The 3405042-T8M300Y oil pipe fully complies with strict national and international standards for automotive fuel system components. It meets China’s GB/T 18411-2019 (Safety Requirements for Automotive Rubber Hoses and Tubing) and the European EN 13228-1 standard for diesel fuel hoses. Furthermore, the materials used are RoHS-compliant (free of lead, mercury, and other hazardous substances) and meet REACH regulations, ensuring environmental friendliness during production and disposal. The pipe also undergoes rigorous durability testing, including 500,000 cycles of bending fatigue (simulating chassis vibration) and 100-hour fuel immersion testing (to verify material stability), guaranteeing reliability in real-world heavy-duty applications
