SSY004971968 Fuel return pipe II Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004971968 Fuel Return Pipe II, a core fuel pipeline component of SANY equipment, is specifically designed for the return of excess fuel and stable oil pressure regulation in fuel systems. It is widely used in the fuel delivery systems of SANY cranes, excavators, and pump trucks, responsible for returning residual fuel from the injectors to the fuel tank, stabilizing oil pressure, and reducing consumption. It is a key component ensuring the efficient and safe operation of the fuel system. Adhering to SANY’s stringent standards, this return pipe undergoes rigorous control in material selection, molding, and sealing testing, ensuring perfect compatibility with original equipment manufacturer (OEM) parts. It effectively addresses the shortcomings of traditional return pipes, such as poor oil resistance, easy leakage, and weak vibration resistance, improving system stability and service life. It is suitable for harsh outdoor operating conditions with high vibration levels, reducing fuel waste and pollution.
As an original equipment manufacturer (OEM) accessory, the SSY004971968 fuel return pipe II meets the design requirements of SANY equipment and can directly replace old and damaged pipes without additional modifications. This significantly reduces maintenance costs and downtime, making it suitable for routine maintenance, emergency repairs, and batch upgrades. It is highly favored by maintenance personnel and enterprises.

Core technical parameters:

– Product Model: SSY004971968
– Product Name: Fuel Return Pipe II (Fuel Return Pipe for Engineering Equipment)
– Material Specifications: The main body is made of oil-resistant rubber/nitrile rubber (NBR), with an inner layer lined with oil-resistant fiber and an outer layer that is anti-aging and wear-resistant. It is resistant to fuel corrosion, high and low temperatures, and has no swelling or leakage. It conforms to GB/T 18944-2013 standard and is compatible with a variety of fuels.
– Structure type: Flexible tubular shape, integrally molded, with uniform and dense tube wall, standard connectors and oil-resistant sealing rings at both ends, tight connection, adaptable to equipment vibration and displacement, combining flexibility and rigidity, and easy to install and wire.
– Dimensions: Pipe length 850mm, inner diameter 16mm, outer diameter 22mm, wall thickness 3mm, connector diameter 18mm, pipe length deviation ±5mm, wall thickness deviation ±0.2mm, bending radius ≥50mm, suitable for compact installation.
– Performance characteristics: Working pressure 0.1-0.8MPa, working temperature -40℃~120℃, sealing leakage ≤0.01ml/min, can withstand vibration, sun exposure and humid conditions, no leakage or cracking, and low resistance to fuel flow.
– Compatible equipment: SANY cranes, excavators, pump trucks and other original equipment, can directly replace the original equipment, compatible with fuel return stations, and compatible with filter and fuel tank connections.
– Installation method: Clip-on + connector mating, with reserved standard interface, no special tools required, easy to install and disassemble, tight connection and reusable, effectively preventing fuel leakage.
– Service life: ≥8000 hours under normal working conditions, far exceeding ordinary return oil pipes. It is weather resistant and anti-aging, suitable for complex fuel and outdoor working conditions, and avoids pipeline aging and leakage failures.
