Hydraulic flanges are mechanical connectors used in hydraulic systems to join two or more components such as pipes, hoses, and cylinders. They are typically made of materials such as steel, aluminum, or brass and come in various sizes and shapes to fit different system requirements. Hydraulic flanges provide a leak-proof seal and are capable of withstanding high pressure and temperature conditions. They are commonly used in applications such as construction machinery, marine equipment, and industrial machinery. Proper installation and maintenance of hydraulic flanges are essential for the safe and efficient operation of hydraulic systems.
