CB-SPS-3FN-WA56000 Thread-to-Connect Hydraulic Coupler | Carterberg
Carterberg’s CB-SPS-3FN-WA56000 is a high-pressure hydraulic quick coupler with a rugged threaded connection, built specifically for compact equipment and portable hydraulic systems. Designed to withstand up to 10,000 PSI operating pressure, this coupling excels in mission-critical scenarios such as hydraulic jacks and rescue tools, where reliability and pressure retention are non-negotiable.
The WA56000 is engineered to deliver zero-leak performance with minimal air inclusion. A screw-to-connect interface combined with poppet-style valves ensures a secure, double-shut-off seal during disconnection. The compact structure and robust surface treatment make it particularly well-suited for space-constrained or mobile hydraulic setups.
Key Features
• Rated up to 10,000 PSI for demanding high-pressure applications
• Thread-to-connect system enables secure connections even under load
• Poppet valve design provides efficient shut-off and prevents fluid loss
• Zinc trivalent plated carbon steel ensures corrosion resistance
• Minimal air inclusion during connection improves hydraulic performance
• Compact design ideal for mobile jacks, lifting systems, and emergency tools

Design and Operation
The CB-SPS-3FN-WA56000 uses a screw-to-connect system to maintain seal integrity even in environments with high vibration or residual pressure. The valve bodies incorporate poppet-style sealing to ensure no leakage during disconnection. Its hex design allows for easy tool-assisted installation in tight assemblies.
