803281319 Return Oil Hose XCMG XDE130 Electric driving dump truck spare parts

The 803281319 return oil hose can solve problems such as poor oil return, joint leakage, hose cracking, bulging, delamination, negative pressure collapse, clip detachment, aging and hardening, and delayed oil return in the oil circuit. It is suitable for replacing old return hoses, hydraulic system maintenance, original equipment manufacturer (OEM) parts, return oil circuit rectification, and hose leakage and disconnection repair. The multi-layer fiber braided hose with an integrated crimped connector is flexible and resistant to deformation, oil and aging, provides stable negative pressure, and is shock-absorbing and tear-resistant, making it suitable for low-frequency negative pressure and bumpy reciprocating oil return conditions in construction machinery.

Core technical parameters:

– Product Model: 803281319
– Product Name: Return Oil Hose
– Material specifications: Oil-resistant composite rubber + fiber woven layer, not easy to dent, crack and leak oil in negative pressure environment.
– Processing technology: Original factory crimped integrated connector, length and curvature calibrated, direct installation and adaptation to the original vehicle’s oil circuit without damage.
– Performance and operating condition adaptability: Rated return oil negative pressure meets the standard, flexible buffer displacement, and adapts to the whole machine hydraulic return system.
– Structural features: Flexible and pressure-resistant return structure, adaptable to vehicle displacement, eliminating the fault of disengagement, oil leakage and obstruction of oil return.

This product has undergone negative pressure leak testing, bending durability testing, oil temperature aging testing, and original vehicle interface compatibility with original factory quality inspection, meeting original factory installation standards and ready to use immediately after installation. It smoothly guides hydraulic oil return, balances negative pressure in the oil circuit, avoids oil leakage problems caused by hose damage, and is compatible with the original factory hydraulic return pipeline complete set of assembly, ensuring smooth oil circuit circulation.
