Coupling and Nipples Series 344

Series 344 35 bar (508 PSI) – 1950l/min (69CFM)

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



Couplings: compatible with series 341, 342 and 346 nipples

Nipples: Not compatible with other series for breathing air applications
