CB-SPB-1F ISO 7241-B Hydraulic Quick Coupling | Carterberg

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

Material & Sealing Options

Designed with affordability and compatibility in mind, CB-SPB-1F supports multiple materials (steel, brass, stainless) and seal options depending on system needs:

Seal Material Max Temperature
Buna-N -40°C to +121°C
Neoprene -54°C to +100°C
EPDM -54°C to +149°C
FKM -29°C to +204°C

Ideal for water lines, compressed air, light hydraulic oil systems, and more.
