160699000121A U-shaped ring Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 160699000121A U-ring is a core sealing component originally supplied by Sany. It is custom-designed for all Sany engineering and mining machinery, and is suitable for harsh working conditions with high dust, oil, and vibration. As a key sealing component for air filter systems and pipeline connections, it adopts a U-shaped cross-section design. It is mainly used for sealing the connection between the upper cylinder assembly, the lower air filter cylinder, and the rain cap assembly. Relying on the elastic sealing surface, it intercepts dust, oil, and water vapor. It is a key component for preventing leakage, ensuring sealing, and protecting the cleanliness of the intake air. It is also the preferred choice for Sany equipment maintenance and bulk procurement, building a solid sealing barrier for the air filter system.
This product is made of high-quality nitrile rubber (NBR) through one-piece molding, with excellent elasticity and good resilience. It has been treated for oil resistance, aging resistance and corrosion resistance, and meets industry standards. With an IP65 corrosion resistance rating, it can resist oil, dust and moisture erosion. It is suitable for working conditions from -30℃ to 110℃, wear-resistant and extrusion-resistant, not easy to deform and age, with a smooth and burr-free sealing surface, stable sealing, and a service life that is 30% longer than the industry average. It can be adapted to vibration environments for a long time and prevents leakage due to seal failure.
The product dimensions are precisely calculated by the original manufacturer, and the cross-section, inner diameter and outer diameter match the connection dimensions of the SANY air filter system. No modification is required. It can be installed simply by embedding it into the sealing groove. No special tools are needed. It can be quickly replaced and is compatible with SANY construction machinery such as excavators and loaders. It is compatible with relevant original parts, fits the sealing surface, and ensures no leakage and no dust intrusion.
