Series 344

  • One-hand operated to connect
  • Automatic safety locking feature
  • Extremely high flow capacity
  • Light weight

 

Series 344 is specially designed for applications with low-weight requirements. The shorter design of the coupling gives it a significantly lower weight than other couplings with the same performance. Series 344 is recommended primarily for breathing air firefighting applications, but is also well suited for diving equipment. Its specially designed valve provides an extremely high rate of airflow. Like most other CEJN breathing air couplings, this series offers one-hand-operated connection, an integrated safety feature that guards against unintentional disconnection, a grip-friendly locking sleeve, and a broad connection range.
