10256979 Sealing Gasket Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 10256979 sealing gasket is a custom-made sealing accessory for engineering machinery. It is suitable for various hydraulic, pneumatic, and fuel systems and component connections in engineering machinery. Its core function is to seal against leakage, dust, and impurities. It also features tight sealing, oil and corrosion resistance, flexibility, and wear resistance. It is suitable for harsh environments such as mines and construction sites, effectively preventing oil and gas leakage, preventing impurities from entering the internal parts, and ensuring the stable operation of the equipment system.
As the core “leak-proof sealing unit” of the sealing system of engineering machinery, this product relies on precise size design to perfectly fit the sealing interface. It has the functions of sealing, dust prevention and buffering. The material is flexible and not easily deformed. It is oil-resistant and aging-resistant. It is easy to install and maintain, and extends the service life of the equipment sealing system. It meets the industry sealing component standards and is a high-quality original part for maintenance, replacement and bulk stocking.
