CB-SPM-1F ISO 7241-B Hydraulic Quick Coupling | Carterberg
CB-SPM-1F is Carterberg’s modular-type ISO 7241-B quick coupling,
designed for OEMs, maintenance systems, and integrators that
require porting flexibility and configuration versatility.
Like other Carterberg ISO B couplings, this model features a
self-sealing poppet valve and ball-lock mechanism, but is
engineered with an emphasis on modular system integration, where
multiple media types, connection styles, or operating pressures
coexist.
If you need one coupling model that can adapt to a variety of
connection types, CB-SPM-1F is your go-to choice.
Key Features
• ISO 7241-B standard dimensional compatibility
• Multi-port/multi-configuration ready – built for integration
• Modular application across fluids, pressures, and connection
types
• Ball latch structure for vibration resistance and secure hold
• Self-sealing poppet valve ensures zero-spill connections
• Compatible with a full range of seals and body materials
• Supports BSPP, NPT, SAE threads in multiple size ranges
