Dongfeng VL truck spare parts Oil seal ring 3104081-ZM01A

Built to eliminate oil leakage—critical for maintaining engine and transmission performance—this seal ring features an advanced triple-layer design. The primary sealing lip (hydrogenated nitrile rubber, HNBR) creates a tight contact with the rotating shaft, blocking 99.5% of engine oil or transmission fluid. The secondary lip acts as a dust barrier, preventing road debris and moisture from entering the lubrication system. A built-in spring applies uniform radial force (4-7N) to the primary lip, compensating for minor shaft wear and maintaining sealing integrity. The seal’s leakage rate is tested to ≤0.005g/h, far below the industry limit of 0.1g/h, ensuring no oil waste or component damage from lubricant loss

Engineered to endure the harsh environment of heavy-duty truck components, the seal ring uses premium materials for exceptional durability. The HNBR sealing lips resist degradation at temperatures up to 150℃—ideal for engine crankshaft applications where exhaust heat raises ambient temperatures. The material also resists swelling from synthetic and mineral oils, maintaining flexibility for ≥150,000km. The metal skeleton (SPCC cold-rolled steel) provides rigid support, while the lip’s PTFE coating reduces friction coefficient by 35%, minimizing wear on both the seal and shaft. This combination ensures stable performance even under 20g vibration loads (ISO 16750-3)

Designed to adapt to diverse operating climates—from Xinjiang’s saline-alkali deserts to northeast China’s frigid winters—the seal ring exhibits strong corrosion and weather resistance. The metal skeleton undergoes zinc plating (12μm thickness) and passivation treatment, passing 1800-hour neutral salt spray testing (ASTM B117) with no red rust. The HNBR material remains flexible at -40℃, avoiding brittleness and cracking in freezing temperatures. It also resists chemical corrosion from diesel, coolant, and road de-icing agents, ensuring structural integrity in industrial or construction environments. These features make it suitable for all-season, multi-region truck operations

The oil seal ring is engineered for efficient installation and long-term cost savings, ideal for fleet operations. 

Its rigid metal skeleton allows easy press-fit installation using a standard seal driver, requiring no specialized tools. 

The outer diameter’s knurled texture enhances retention force with the housing bore, preventing slippage during operation. 

Installation takes a single technician 10 minutes per seal, 50% faster than non-OE alternatives. By preventing oil leakage,

 it reduces lubricant replenishment costs by 30% and avoids expensive repairs caused by oil-contaminated components. Backed by a 1-year/100,000km warranty,

 it is a cost-effective solution for heavy-duty truck maintenance
