Product description

Description
Quick release couplings uncouple automatically under excessive tensile load, preventing separation of the hose lines.
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.
