803403426 Diesel hose assembly XCMG XDE130 Electric driving dump truck spare parts

The 803403426 diesel hose assembly effectively improves upon common problems found in ordinary oil hoses, such as insufficient pressure resistance, oil leakage and pressure loss, rubber aging, bending cracking, layer peeling, loose joints and sealing failure, and poor weather resistance. It is widely applicable to various scenarios including fuel line replacement in construction machinery, oil line fault repair, routine equipment maintenance, and original equipment manufacturer (OEM) assembly. The product employs a three-layer composite structure: a high-strength oil-resistant inner layer, a densely braided pressure-resistant middle layer, and a weather-resistant protective outer layer. Combined with original high-precision riveted joints, it undergoes multiple processes including high-pressure shaping, anti-aging modification, and moisture and corrosion protection. This results in strong overall pressure resistance and excellent sealing performance, making it suitable for various harsh working conditions such as heavy-duty operations, continuous vibration, oil contamination, and large temperature differences between day and night.

Core technical parameters:

– Product Model: 803403426
-Product Name: Diesel Hose Assembly
– Material specifications: Three-layer composite oil-resistant special material, pressure-resistant, wear-resistant, anti-aging and non-deteriorating, original factory precise pipe diameter size, and precise fitting during installation.
– Processing technology: integral vulcanization molding, joints are reinforced by high-pressure riveting and sealing, and have passed multiple pressure resistance and anti-seepage tests. It is easy to disassemble, assemble, and maintain.
– Performance and operating condition adaptability: Resistant to diesel corrosion, high pressure leak-proof, vibration and tensile strength, stable performance in high and low temperature environments, and not prone to delamination and cracking after long-term use.
– Structural features: Original factory integrated assembly design, excellent flexibility, close-fitting wiring, uniform and stable flow, effectively preventing problems such as oil pressure loss, leakage, and insufficient oil supply.

This product undergoes rigorous quality control, including high-pressure testing, sealing inspection, and aging durability testing, fully complying with original equipment manufacturer (OEM) standards and industry usage standards for construction machinery. Replacing the faulty component with this product completely resolves potential problems such as fuel line leaks, pressure drop, aging and damaged lines, and loose connections, effectively eliminating fuel waste and equipment safety hazards, reducing the frequency of fuel line failures and maintenance costs, continuously ensuring the stable operation of the equipment’s engine fuel supply system, and improving the overall machine’s operational stability and service life.
