O"" Ring - Buna
Hydraulic Seal · Buna O-Ring
This is a standard AS568-115 O-ring, a crucial sealing component for various systems on concrete mixers. Made from durable Buna-N (Nitrile) 70 durometer rubber, it offers excellent resistance to petroleum-based hydraulic fluids, oils, gasoline, and water, making it ideal for sealing connections in hydraulic lines, pumps, valves, and cylinders. This O-ring would be used to replace a worn or damaged seal during maintenance to prevent leaks and ensure the proper functioning of the equipment. Its specific dimensions are an inner diameter of 0.674 inches, an outer diameter of 0.880 inches, and a cross-section of 0.103 inches.
