To ensure a seamless connection, five factors must be carefully considered when choosing the right style and material for an application. These factors are size, temperature, application, media and pressure.


OD pipe and wall thickness must be taken into account for all piping fittings. With most types of end pipes, there are limitations to the thickness of the pipe wall. System pressure, flow, temperature and operating environment also affect size.


The temperature of the system and the environment in which the hydraulic pipe fittings can operate depends on the type of material, the protective liner or coating and the sealing material.


The system environment – such as vibrations, pressure peaks and external thermal and mechanical load – also affects the choice of mounting material and whether a protective coating is required


The type of liquid transported also directly affects the choice of assembly and sealing material.


The nominal dynamic pressure of the component must be equal to or greater than the system pressure.
