CEJN / Series 550

Series 550 couplings feature an easy-to-grip design and require only a low connection force.
They are smaller and more compact and generate higher flows than comparable designs.
Series 550 couplings have an extremely low noise level upon disconnection.
The series includes anti-hose whip nipples.
The Series 550 vented safety version is disconnected in two stages in order to vent the coupling and minimize the risk of sudden component separation, which has the potential to cause operator injury.
Its unique, balanced-valve design makes it extremely easy to connect, regardless of system pressure.
The safety version is also ideal for multiple connection points, such as manifold applications in which low connection force is required.
It complies with ISO Standard 4414 and EN 983.

• Strong and durable
