CB-SPB-1F-A ISO 7241-B Hydraulic Quick Coupling | Carterberg
Carterberg's CB-SPB-1F-A coupling is a durable quick connect solution built for medium-to-high pressure fluid systems, fully compliant with ISO 7241-1 Series B specifications. Constructed from corrosion-resistant brass, this model combines a ball-lock mechanism, a self-sealing poppet valve, and a protective dust cap into one reliable coupling unit.
Designed for quick connection and disconnection without fluid loss, CB-SPB-1F-A is suitable for a wide range of hydraulic, pneumatic, and water systems.
Key Features
• ISO 7241-B dimensional compatibility
• Brass body construction – corrosion-resistant and economical
• Integrated dust cap to protect connection ends from debris
• Ball-lock structure for safe, vibration-resistant coupling
• Poppet valve shutoff minimizes spillage during disconnect
• Available in BSPP, NPT, SAE thread options
• Flow-efficient design with minimal pressure drop
Material & Performance Benefits
Made entirely of brass, CB-SPB-1F-A offers a strong balance of mechanical integrity and corrosion resistance. Its compact form and clean disconnection design make it especially suitable for mobile applications and semi-open environments.
Unlike stainless steel models aimed at aggressive chemical resistance, this model is engineered for reliability in lubrication, compressed air, water supply, and general hydraulic circuits.
