CB-SPS-3FN-CVV Threaded Sleeve-Lock Hydraulic Coupling
The CB-SPS-3FN-CVV is a high-durability threaded quick coupling engineered by Carterberg, built to withstand hydraulic pulses, frequent flow surges, and harsh outdoor environments. Its compact sleeve-lock structure allows for secure manual connection with matching threads on the nipple side, ideal for construction equipment, excavators, and fluid transfer systems.
Manufactured from solid barstock and treated with advanced chrome plating, this model offers excellent corrosion resistance and consistent alignment under vibration.
Key Features
• Threaded Sleeve Lock Mechanism
Secure connection achieved by threading female sleeve onto male nipple, resistant to accidental decoupling under pressure.
• Anti-Impulse Valve Design
Specially designed to mitigate damage from sudden hydraulic surges and pressure spikes.
• Valve Retainer with Positive Stop Ring
Ensures accurate internal valve alignment, maintaining reliable shut-off under dynamic conditions.
• Machined Chrome-Plated Steel Construction
High corrosion resistance and long service life in outdoor or mobile hydraulic systems.
• Interchangeable Profile
Compatible with FASTER CVV series and STUCCHI VD series threaded couplers.
