SSY004971970 Fuel Inlet Pipe III Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY004971970 fuel inlet pipe III, a core fuel delivery upgrade component for SANY equipment, is specifically designed for the fuel supply systems of medium and large-sized equipment. It is widely used in SANY cranes, excavators, pump trucks, and other heavy-duty equipment, responsible for delivering fuel from the tank to core components such as the engine and filter, ensuring smooth supply under heavy-duty conditions. It is a key component for the stable operation of the equipment’s power system. Adhering to SANY’s stringent standards, this inlet pipe undergoes strict control in terms of materials, molding, and pressure resistance sealing tests. It is compatible with original equipment manufacturer (OEM) parts and effectively solves the problems of poor oil resistance and easy leakage of traditional and Type II inlet pipes. This improves the stability and service life of the fuel system, making it suitable for outdoor conditions with high vibration, alternating high and low temperatures, and heavy-duty impacts, and conforms to GB/T 2423.5-2019 standards.

Core technical parameters:

– Product Model: SSY004971970
– Product Name: Fuel Inlet Pipe III (Engineering Equipment Dedicated, Upgraded from Type II)
– Material Specifications: Upgraded multi-layer composite structure, with an inner layer of high oil-resistant HNBR, a middle layer of high-strength metal braided reinforcement, and an outer layer of thickened weather-resistant protection. The sealing surface is made of oil-resistant fluororubber, which has been treated with anti-corrosion and anti-aging treatment. It is resistant to corrosion from various fuels, has no swelling or leakage, and has a volume swelling rate of -3% to +15%, which meets the GB/T 2423.5-2019 standard.
– Structure type: Flexible tubular, integrally molded, with uniform tube wall, upgraded standard connectors at both ends, enhanced combined sealing, pressure resistance and vibration resistance are superior to Type II, can adapt to high-frequency vibration of heavy-duty equipment, facilitates wiring, and reduces oil and gas penetration.
– Dimensions: Pipe length 950mm, inner diameter 18mm, outer diameter 25mm, wall thickness 3.5mm, connector diameter 20mm, pipe length deviation ±5mm, wall thickness deviation ±0.2mm, bending radius ≥60mm, suitable for fuel lines with an inner diameter of 18-25mm.
– Performance characteristics: Working pressure 0.2-1.0MPa, burst pressure ≥3.0MPa, working temperature -40℃~120℃, sealing leakage ≤0.01ml/min, low oil and gas permeability, can withstand high frequency vibration, high pressure and outdoor working conditions, no leakage or cracking, and smooth fuel delivery.
– Compatible equipment: SANY cranes, excavators, pump trucks and other original heavy-duty equipment. It can directly replace the original model and Type II fuel inlet pipe, and is compatible with fuel supply systems, fuel tank, engine and filter connections.
– Installation method: snap-fit ​​+ connector mating, standard interface reserved, hole accuracy ±0.03mm, no special tools required, easy to install and disassemble, reusable, and can reduce leakage when used with sealant.
– Service life: ≥9000 hours under normal working conditions, far exceeding ordinary and Type II oil inlet pipes. It is weather-resistant, anti-aging, and wear-resistant, suitable for heavy-duty equipment and complex working conditions, and avoids pipeline aging, swelling and leakage.

The SSY004971970 fuel inlet pipe III, with its upgraded materials, precise dimensions, and original equipment manufacturer (OEM) compatibility, has become the preferred choice for fuel maintenance and upgrades of Sany heavy-duty equipment.
