Product description

Description
Screw couplings are designed for high pressures and pressure pulses.
It is advised to combine couplings of the same manufacturer only.
Further information
If fitted correctly, the screw sleeve completely covers the brake ring.
The self-locking thread prevents unwanted loosening due to vibrations.
The robust construction makes them ideal for use in harsh conditions.
The indicated working pressure refers to the coupling only and is dependent on the selected connection types.
