Series 218, 100 MPa

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.

Technical data
Nominal flow diameter: 4.5 mm (11/64Inch)
Flow capacity: 15.0 l/min (3.3 GPM UK)
Max. working pressure: 100.0 MPa
Min. burst pressure: 280.0 MPa
Temperature range: -30°C — +100°C (-22°F — +212°F)
Material coupling: Hardened, zinc chromate plated steel
Material nipple: Hardened, zinc chromate plated steel
Material seal: Nitrile (NBR) other sealing material on request
Comment: Avoid loading the nipple while disconnected. Dynamic load on nipple while disconnected may lead to seal damage.

Flow capacity is measured at 0.4 MPa pressure drop.
