Rigid coupling QTC series

for panelsindustrialheavy-duty

Description
These QTC flat-face panel-mount couplings are engineered for CE heavy-duty applications and for integration in custom automatic multiconnection systems. They enable rapid change of hydraulic tools from the operator cab and allow front installation on a panel using Seeger rings. Optimized internal components reduce energy consumption while maintaining mechanical durability.
