high pressure hydraulic quick couplings cb 10218
CB-10218 Ultra High-Pressure Hydraulic Coupling | 100 MPa Compact Design
The CB-10218 is an ultra high-pressure quick coupling engineered for demanding hydraulic systems requiring up to 100 MPa (14,500 PSI) working pressure. Compact and precise, it features leak-free disconnection, a mechanical lock ring, and CEJN 218 compatibility, making it ideal for bolt tensioners, pressure tools, and controlled hydraulic operations.
Its G 3/8" threaded interface, hardened steel construction, and high-flow profile allow it to withstand frequent high-pressure cycles with consistent performance.
Key Features & Benefits
• Rated for 100 MPa (14,500 PSI)
Designed for extreme hydraulic applications requiring high reliability and consistent sealing.
• Leak-Free Disconnection
Prevents fluid loss during uncoupling, protecting operators and minimizing contamination.
• Compact Profile
Only 73.4 mm long and 34.6 mm in diameter, ideal for tight assembly areas.
• Positive Locking Mechanism
Female coupling includes an automatic mechanical lock ring to prevent accidental disconnects under pressure.
• High Flow Rate
Delivers up to 15 L/min through a narrow passage, supporting responsive hydraulic control.
• Material & Seal
Quenched steel with zinc coating for durability; standard NBR seals with optional rubber-metal interface.
• Threaded G 3/8” Connection
Ensures secure installation across test equipment and ultra high-pressure devices.

Compatibility Notes
The CB-10218 is structurally and functionally compatible with CEJN 218 Series couplings. Designed to match thread dimensions, flow paths, and sealing interface, it can serve as a direct replacement in most standard 100 MPa tools and fixtures.
Frequently Asked Questions (FAQ)
Q: Can CB-10218 be connected under pressure?
A: No. The system must be depressurized before disconnection. The mechanical locking ensures safety after full engagement.
Q: Is this interchangeable with CEJN 218 parts?
A: Yes. CB-10218 offers drop-in compatibility with CEJN 218 Series male and female couplings.
Q: Is this suitable for dynamic or pulsating flow?
A: Yes, within the rated pressure and temperature range. For frequent cycling, optional metal sealing is recommended.
