Series 345 is a double shut-off series with both a valved coupling and nipple.
The specially designed valve provides an extremely high rate of airflow. This
series is well-suited for breathing air diving applications and for applications
that demand a closed system when disconnected, such as surface air diving. Like
most other CEJN breathing aircouplings, Series 345 offers one-hand-operated
connection, an integrated safety feature that guards against unintentional
disconnection, a grip-friendly locking sleeve, and a broad connection range.
