Flat face screw VT RoT-lock is the Stucchi solution for high demanding applications, where torsions and impulses are involved.
The “VT RoT-lock” screw flat face coupling series is the technological solution to demanding hydraulic applications. The main news compared to the other Stucchi flat face screw couplings is the presence of an axial bearing that allows the rotation of the hose.
The screw connection system eliminates premature wear and the “brinelling” caused by a mechanical locking ball system. This makes the “VT RoT-lock” series suitable for high operating and impulse pressures. The triple valve system allows connection of the coupling safely even in presence of high internal residual pressure and at the same time avoiding fluid loss.
