CB-SPS-3FN-BA Threaded Sleeve-Lock Hydraulic Coupling
The CB-SPS-3FN-BA from Carterberg is a threaded sleeve-lock hydraulic quick coupler engineered for high-pressure and high-impulse hydraulic systems. Designed with durability and secure engagement in mind, this coupling is ideal for mobile equipment, agricultural machinery, and heavy-duty industrial setups.
Its solid steel body with chrome-plated treatment resists corrosion, while the precision-machined threaded locking sleeve delivers enhanced vibration resistance and prevents accidental disconnection in pulsating fluid environments.
Key Features
• High Impulse-Resistance Design
New-generation valve structure offers advanced sealing and durability under flow surges.
• Threaded Sleeve Lock Mechanism
Securely mates with matching male thread on the nipple, ensuring pressure-tight integrity.
• Steel Construction + Chrome Plating
Built from solid barstock for strength, with enhanced rust resistance.
• Manual Connection
Both coupler halves must be hand-threaded for a full connection—no tools required.
• Interchangeable Design
Compatible with GROMELLE 6000 Series and HOLMBURY TGW Series.
