- The automatic lock sleeve integrated in the connection system prevents the accidentaldisconnection
- Axial bearing integrated in the male coupling to allow the rotation of the hose avoiding the unscrewing and damaging of the parts
- Robust screw connection system that eliminates the premature wear and damages, making the product life much longer
- Double start thread allows to connect and disconnect in half the time compared to single thread coupling
- Black rings for visual checking of proper connection of the couplings
- Connection under residual pressure is allowed in both sides, the internal valve system allows an easy connection
- Flat face is easy to clean, reducing the inclusion of contamination to the hydraulic circuit
- Minimal fluid loss during disconnection, reducing contamination to the environment
- Minimal air inclusion during connection/disconnection
- Internal valve design creates minimal pressure drop, maintaining circuit efficiency in the system
- The modular design allows flexibility with a wide range of configurations
- High resistance at impulse pressures
- Safe and simple to use

VT RoT-lock
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.
