Series 348 -



Series 348

Series 348 offers a partial stainless steel construction with a lower connection force than competitive styles. The series features a valved nipple that makes the double shut-off design well-suited for fire-fighting applications. Like most CEJN breathing air couplings, Series 348 couplings offer one-hand-operated connection and an integrated safety feature that guards against unintentional disconnection.
