Series 346 -



Series 346

The AISI 316 stainless steel construction of Series 346 makes it suitable for agressive applications, such as offshore duty. Its special valve design provides a high rate of airflow. Like most CEJN breathing air couplings, Series 346 offers one-hand operated connection, an integrated safety feature that guards against unintentional disconnection, a grip-friendly locking sleeve, and a broad range of connections.
