CEJN® Series 218 Couplings - Industrial Ancillaries

CEJN® Series 218 Couplings

  • 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 allround coupling that works well in most applications, even if it is mainly recommended where large flow rates are required.
