Parker Hydraulic DIN Fitting

The Parker EO-PSR fittings produce high pressure, leak free connection of tubes and components in hydraulic systems. The basic function of EO-PSR is the controlled progressive bite of the EO-PSR into the tube due to a unique internal geometry. Assembly process is according to the EO Progressive ring instruction. The design allows a 100 percent preassembly for an easier final assembly.
