Flat Face - Stucchi USA

Connect Under Pressure
Threaded Flat Face Coupling
Overview
Stucchi VP series is the ultimate
solution and most popular for
hydraulic circuit applications
subject to high pressure
impulses, and circuits which
experience high residual or
trapped pressure in a line. The
VP thread-to-connect design
eliminates premature wear
or brinelling associated with
locking ball designs subjected
to high impulse pressures. The
patented internal valve allows
connection and disconnection
with high residual pressures.
Flat face design avoids loss of
hydraulic fluid during connection/
disconnection. Flat face design
is easy to clean, limiting
contamination into the circuit.
Flat Face: Threaded Coupling
Applications & Features
Series: VP
Interchange: None
- Connect/disconnect with residual pressure up to 25 MPa/3625 psi
- Thread coupling system eliminates brinelling, premature leakage
- High working pressures: up to 40-60 MPa/5800-8700 psi
- Valve limits fluid movement during connection avoiding damage
to other elements of circuit
- Low connection force required
- Safety auto-lock feature upon connecting
Fire Tested and Lloyd’s Certified * in compliance with
API 16D Test and EUB Directive 36.
*Lloyd’s document available upon request
- Excavators w/auxiliary
line for attachments:
thumbs, grapples,
hammers
- Oil Field, well head drives,
porta-power
- Cranes, drilling machines,
all large equipment needing
junction points in circuit
- All construction equipment
applications with higher
pressure requirements
or issues of connecting/
disconnecting tool
attachments under
residual pressure
- Connect/disconnect up
to 25MPa/3625 psi
residual pressure
- Save time changing tools
