CEJN Breathing Air Products

Breathing Air Couplings & NipplesCEJN Breathing Air couplings have a high-flow rate, a broad connection range and require only minimal force to connect. With the vital function of supplying breathing air, the need for safety and reliability is of the utmost importance.

The launch of a new H2S push-to-connect coupling, Series 340, is a step to meet customers in the demanding area of safety breathing air and cascade systems within the oil and gas industry.

 

  • Automatic safety-locking feature
  • Extremely high flow capacity
  • One-hand operation
