The CB-10125 hydraulic quick coupling is purpose-built for ultra high-pressure systems operating up to 250 MPa (36,250 PSI). With a valveless plug, metal-to-metal seal, and compact G1/4" thread configuration, it’s a trusted choice for hydraulic bolt tensioners, bearing pullers, and other equipment used in precision high-force applications.
This model is part of Carterberg’s CEJN 125-compatible series and offers seamless, leak-free connection and disconnection, even under extreme load. Its CMS metal seal (120° cone) ensures safety and repeatability across frequent cycles.
• Rated for 250 MPa Working Pressure
Built to handle extreme hydraulic forces in controlled tooling and testing systems.
• Compact Dimensions
Total length of just 73.8 mm and 30 mm outer diameter — ideal for confined assembly spaces.
• No Valve on Plug Side
Simplified internal structure minimizes pressure drop and facilitates faster pressure equalization.
• Secure CMS Metal-to-Metal Sealing
Eliminates reliance on O-rings in critical zones, delivering superior performance at ultra-high pressure.
• Standard Dust Caps & Safety Lock
Each unit includes integrated safety lock and protective caps to prevent contamination and accidental release.
• CEJN 125 Series Compatible
Functionally interchangeable with CEJN 125 products, while offering improved supply flexibility and cost efficiency.

The CB-10125 is fully compatible with CEJN 125 series, including physical size, sealing interface, and hydraulic performance. While interchangeability is ensured, we recommend verifying seal materials (NBR vs Viton) and maximum torque settings during replacement or retrofit scenarios.
Q: Can CB-10125 be used in dynamic pressure systems with pulsation?
A: It is suitable for ultra high-pressure, static load cycles. For pulsating systems, consult us for reinforced variants.
Q: Is the coupling completely valve-free?
A: Yes. The male half (plug) is valve-free to minimize fluid restriction. The system must be depressurized before disconnection.
Q: Is this compatible with CEJN 125 tools?
A: Yes. CB-10125 is a functionally compatible replacement with CEJN 125, designed for use in bolt tensioners, pullers, etc.
