| Quick Connect Couplings for Breathing Air
Applications |
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
onehand-operated connection, an integrated safety feature that guards against
unintentional disconnection, a grip-friendly locking sleeve, and a broad
connection range.
