Product description

Description
Tube couplings are designed for high pressures and pressure pulses.
Further information
Flat seal tappets ensure minimal oil leakages and air admittance when coupling.
The robust construction makes them ideal for use in harsh conditions with major pressure fluctuations.
The indicated working pressure refers to the coupling only and is dependent on the selected connection types.
A coupling safety factor cannot be given for size 5.
