Hydraulic Coupling No Longer Uses Steel

When Parker Hannifin, Mainz-Kastel, Germany was looking to replace the steel components of its RSD quick couplings with one single injection molded component that reduced the number of components to be assembled and control the overall production costs, they selected VICTREX® PEEK(TM) polymer.

The RSD series couplings are used to rapidly and easily connect and disconnect the hydraulic lines between a tractor and its various items of equipment (trailer, plough, etc.) without using any tools.

The technology of the RSD coupling allows for a completely safe connection of a male connector, whether pressurized or not, under adverse conditions, such as under a maximum pressure of 250 bar (3626 psi), and withstands a return flow rate that may reach 190 l/min (50.2 gallons/min) and even beyond for a few seconds at a temperature close to 120°C (248°F).
