SKYLAND Stainless Steel Ferrule Tube Fittings, For Hydraulic Pipe, Size: 3/4 inch

Tube fittings connect runs of tubing (for in-line, offset, multi-port, and mounting configurations) to other tubing sections, pipe, hose, or other components. Systems are typically configured with straight sections connected by fittings or specially formed connections and joints. Fitting construction and material specifications are application-dependent; consulting the fitting supplier is typically a wise route for optimizing component selection. However, most tube fittings correspond to either hydraulic or pneumatic systems. The basic system type is the first step to determining the type of fittings right for the application. Hydraulic applications involve the transfer of liquid fluids such as water and other chemical solvents. Hydraulic fittings must have seals which prevent the leakage of liquid and often be resistant to rust or other possible chemical corrosion. Pneumatic applications involve the transfer of gases. Pneumatic fittings must have very tight seals to prevent gas leakage and must be resistant to chemical corrosion. Other applications such as structural design also incorporate tube fittings. These fittings must have strong physical integrity but typically do not require sealing because they do not carry fluids. Compression fittings are fittings which connect tubes using compression on a gasket, ring, or ferrule. The compression is typically made by tightening a nut onto the fitting over the tubing and ferrule, compressing and securing the tubing inside. Standard compression fittings do not require tools to assemble, making them convenient for quick, simple installation. However, they cannot withstand very high pressures and do not have as much flexibility as soldered fittings, making them less functional in systems with vibration, thermal cycling, and other dynamic forces. They also come in a limited number of materials (most commonly brass) and are best suited for metal on metal connections.
