151003110259A Hose Assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 151003110259A hose assembly is a core transmission component of the hydraulic system of construction machinery. It is precisely adapted to various equipment such as Sany excavators and loaders, and is compatible with hydraulic lines and connectors of the same specifications. As the “flexible blood vessels” of the hydraulic system, its performance stability directly affects the overall operating efficiency of the equipment. With its precision crimping process, excellent weather resistance, and strict quality control, it has become the preferred choice for operation and maintenance. It effectively solves the pain points of traditional hose assemblies such as easy detachment, leakage, insufficient pressure resistance, and poor fatigue resistance, reducing operation and maintenance costs and ensuring the efficient and smooth operation of the hydraulic system.
This product uses precision crimping with imported German CNC equipment, with crimping force error controlled within ±2%, ensuring a tight connection between the connector and the hose. It will not detach or leak under high temperature, high pressure, and pulse conditions, meeting the core safety requirements for hose assembly installation and use. It has excellent bending performance and a reasonable minimum bending radius, which can flexibly adapt to complex equipment installation spaces, reduce the number of connectors used, and reduce the risk of leakage. At the same time, it has good anti-vibration and anti-fatigue performance, reducing the damage to the hose body caused by equipment vibration and reducing the downtime failure rate.

Core technical parameters:

– Product Model: 151003110259A
– Standards implemented: GB/T 3683-2023, EN 856 2SN (Complies with the latest national and international standards, quality is guaranteed)
– Nominal inner diameter: 15mm (precisely adapts to the fluid transport needs of equipment, highly adaptable, and conforms to the national standard nominal inner diameter specification range)
– Working pressure: 20MPa (rated high pressure, suitable for hydraulic system working requirements, stable and reliable, meeting high pressure transmission standards)
– Bursting pressure: 60MPa (3 times the working pressure, with sufficient safety margin to eliminate the risk of bursting and comply with safety regulations)
– Operating temperature: -40℃~100℃ (Wide temperature range, adaptable to various regional working conditions, conforms to the national standard operating temperature range for oil-based fluids)
– Structural materials: Inner layer nitrile rubber (NBR) + Middle layer double-layer steel wire braided reinforcement + Outer layer aging-resistant synthetic rubber
– Crimping process: CNC precision crimping (error ±2%) ensures a tight fit between the connector and the tubing, eliminating the risk of detachment.
– Compatible media: Commonly used fluids in engineering machinery and equipment such as petroleum-based hydraulic oil and water-based hydraulic oil (meeting national standard requirements for compatible media).
– Suitable for: Hydraulic systems of Sany excavators, loaders, and other equipment, adapting to the hydraulic transmission replacement needs of various construction machinery.

Adhering to a stringent quality control philosophy, each 151003110259A hose assembly undergoes pressure pulse testing, burst testing, joint pull-out testing, and visual inspection. Before installation, a pressure holding test at 1.5 times the working pressure is conducted according to specifications to ensure that the hose body is free from delamination and cracks, the joints are secure and leak-free, the dimensions are accurate, and the markings are clear and legible. It meets the standards for engineering machinery equipment accessories, is easy to install, and can directly replace old hose assemblies, significantly improving equipment operation and maintenance efficiency.
