Cejn 218 Series Hydraulic Couplers & Fittings
Specialised Force is the authorised Australian Distributors for the Cejn range of high-pressure hydraulic couplers (also known as snap couplings or quick disconnect couplings) and hydraulic fittings.
The Series 218 is a CEJN original that, despite very small outside dimensions, gives an extremely high flow. Both the patented sealing design and non-drip connection and disconnection are standard on CEJN’s High-Pressure range. The coupling also has a safety ring for the locking sleeve to prevent accidental disconnection. Plastic dust caps are standard on both coupling and nipple. The series is an all-round coupling that works well in most applications, even if it is mainly recommended where large flow rates are required.
