The CB-SPB-1F is Carterberg’s cost-efficient and space-saving
solution in our ISO 7241-B hydraulic coupling lineup. It’s engineered for equipment designers and system operators who
require reliable connection in compact or lower-pressure systems,
without compromising interchangeability or sealing performance.
This model integrates the same trusted ball-latch mechanism and
poppet valve design as our higher-tier models, but with economical
packaging and simplified configuration, making it ideal for
widespread industrial use.
Key Features
• Compliant with ISO 7241-1 Series B dimensions
• Compact and lightweight body – ideal for tight installation
spaces
• Ball-lock design ensures quick, tool-free coupling
• Self-sealing poppet valves minimize fluid loss
• Suitable for low-to-medium pressure systems
• Available in carbon steel, brass, or stainless options
• Cost-effective without sacrificing compatibility
