Product Description
CB-SPS-3FN-BC Threaded Hydraulic Quick Coupling
The CB-SPS-3FN-BC is Carterberg’s compact threaded hydraulic coupler, designed for mobile equipment that demands reliable, low-spill connections in tight spaces. Featuring a wing nut locking system on the female half, it allows manual operation even under residual pressure—no tools required.
Engineered for dump trucks, agricultural machinery, and construction vehicles, the CB-SPS-3FN-BC uses a dual shut-off design with low spillage and minimal air inclusion. Its zinc-plated steel construction ensures corrosion resistance and long-term durability under field conditions.
Key Features
• Threaded Wing Nut Connection (Female Side)
Allows safe connection under pressure using manual hand force.
• Dry-Break Valve Design
Dual shut-off minimizes fluid loss and air ingress on disconnection.
• Field-Proven Steel Construction
Hardened components and surface plating ensure longevity in rugged outdoor use.
• NBR Seals (Standard)
Compatible with most petroleum-based hydraulic fluids; Viton and EPDM available on request.
• Interchange Compatibility
Designed for functional interchange with major European dry-break coupler standards
