CB-10116 Stainless Steel Hydraulic Quick Coupling | CEJN 116 Compatible
The CB-10116 is a compact, stainless steel hydraulic quick coupling engineered to meet the high demands of ultra high-pressure systems in corrosive environments. Designed as a fully compatible alternative to the CEJN 116 Series, this model combines mechanical safety features, drip-free operation, and CEJN’s 120° CMS metal-seal cone to deliver superior sealing reliability under extreme pressure.
Ideal for torque tools, tensioners, and portable hydraulic equipment, the CB-10116 is your high-integrity choice when failure is not an option.
Key Features & Advantages
• 100% Stainless Steel Construction: Corrosion-resistant and suited for aggressive environments including marine, chemical, and offshore systems.
• Compact Body Design: Only 51.2 mm in length and 24.5 mm in diameter, perfect for tight-space applications.
• CMS Metal Seal (120° Cone): CEJN-compatible metal-to-metal sealing with high temperature and chemical resilience.
• Leak-Free Operation: Designed for zero spillage during connection and disconnection.
• Valve-Free Male Coupler: Optimized for systems where fluid direction is regulated externally.
• Safety Locking Ring: Female coupler includes a mechanical ring to prevent accidental disconnection.
• High-Pressure Rating: Operating pressure of 150 MPa (21,750 PSI), with a minimum burst pressure of 300 MPa.
• G 1/4" Threaded Connection: Compatible with common industrial hydraulic interfaces.
• Standard Dust Caps Included: Extend coupler life and protect internal surfaces. Optional aluminum caps available.

FAQ
Q: How does CB-10116 differ from CB-10125 or CB-10218?
A: CB-10116 is stainless steel and features a CMS metal seal. CB-10125 and 10218 are typically carbon steel with O-ring sealing. Also, 10116 has a more compact design and no internal valve on the male side.
Q: Is CB-10116 suitable for chemical or marine applications?
A: Yes. The full stainless-steel build and leak-free design make it ideal for corrosive and sensitive environments.
Q: Can CB-10116 replace CEJN 116 directly?
A: Yes. It is fully dimensionally and functionally compatible.
