O-ring Caterpillar C7/C9/C10/C11/C12/C13/C15/C18/C27/C32/3114/3116 107-5769

Product description

The O-ring seal with an inner diameter of 79.38 mm (catalog number 107-5769) is a new product that will perform excellently in various applications in construction machinery. O-rings serve as static seals and, in some cases, dynamic seals. Made from materials specifically chosen for the fluids, temperatures, and pressures present in Cat engines and machines, they provide resistance to extrusion and excellent resilience, allowing for effective sealing under compression. Some rings are coated with PTFE, which minimizes the risk of twisting and cutting during installation. Our O-rings are produced with precise dimensional tolerances, ensuring a perfect fit in grooves while maintaining the appropriate level of compression. The range includes 2,500 O-ring seals of various sizes and materials, making them the best solution for Cat mobile machines and other manufacturers. Cat sealing systems protect costly parts from leaks and contaminants, safeguarding your investment. O-rings are used in many static and dynamic connections in Cat machines and engines. The HNBR material from which the ring is made withstands temperatures from -40 to 115°C and is resistant to fuels, oils, and greases, as well as abrasion and cutting. The product is compatible with diesel fuels, lubricants, refrigerants, and silicone fluids, as well as water-based engine coolants. However, contact with gasoline containing aromatic compounds, brake fluids, and chlorinated hydrocarbons should be avoided. The main sealing material is a rubber element with a hardness of 78A, ensuring flexibility and durability in challenging working conditions.
