Hydraulic fittings are essential components used in hydraulic systems to connect hoses, pipes, and tubes. They ensure a secure and leak-free connection, allowing fluid to flow efficiently through the system. These fittings come in various shapes and sizes, designed to accommodate different pressure levels and fluid types. Typically made from materials like steel, brass, or plastic, hydraulic fittings can be threaded, flanged, or crimped, depending on the application. Proper selection and installation of these fittings are crucial for the safety and performance of hydraulic machinery, such as excavators and forklifts.
