CB-SPS-3FN-96 Threaded Hydraulic Coupler | Carterberg Wing-Nut Type for Flange Mount
The CB-SPS-3FN-96 is a wing-style threaded hydraulic quick coupler engineered for applications requiring reliable connection under residual pressure and vibration. Designed with a bi-directional shut-off structure and flange-mounting capability, this model is ideal for systems where fast manual connection and secure fixation are critical.
Compatible with common flange standards, it offers both versatility and strength for mobile hydraulics, oilfield systems, and high-pressure transfer lines.
Key Features
• Wing-handle design for easy manual connection without tools
• Threaded connection with integrated dual shut-off valves (no fluid loss)
• Residual pressure connection capability for high-pressure or pulsating systems
• Flange mounting interface, suitable for panel or bulkhead installation
• Available in three sizes: 3/4", 1", and 1-1/4"
• Compatible with similar-profile threaded couplers for flexible use
• Vibration-resistant body, suitable for mobile or heavy-duty hydraulic setups.

Applications
• Mobile hydraulic systems with confined panel spaces
• Oilfield and chemical service vehicles
• High-pressure systems requiring residual pressure tolerance
• Equipment with strong vibration or shock loads (e.g., drilling units, winches)
Why Choose CB-SPS-3FN-96 Over Standard Threaded Couplers?
Compared with conventional hex-style threaded couplers, the 96 wing type offers:
• Easier manual tightening/loosening under pressure
• Quicker visual alignment during installation
• Simplified panel mounting with consistent interface sizes
• Reliable connection where frequent disassembly is required
