Safely connected - for your safety
For breathing air, safe and solid equipment is needed. CEJN quick-connect couplings have an extremely high rate of airflow. One-hand operated connection, integrated safety feature that protects against unintentional disconnection, a grip-friendly locking sleeve, and a broad connection range are features that will help protect your breathing and your life.
Significant features of CEJN breathing air couplings
- Automatic safety lock
- High flow capacity
- One-hand operation
- Fulfills and surpasses all breathing air requirements
- Available with Stream-Line re-usable fittings
- Compact dimensions
Stream-Line - A reliable connection
The Stream-Line couplings are a perfect fit for CEJN PUR hoses and it can easily be removed and reused with just a few basic tools. As crimped hoses or fittings with hose clamps will eventually start leaking, a Stream-line connection has proven to be a reliable concept that will remain leak-free during the coupling's entire service life. The Stream-line connection consists of a CEJN PUR hose with a cap nut connection to a perfectly matching quick coupler to provide a long-term reliable connection.
Safety couplings designed for H2S
The CEJN series 340 is specially designed for H2S safety breathing air and cascade systems. 100% tested and greased according to breathing air regulation and they are available with re-usable fittings. The “push-to-disconnect” safety function disengages the coupling in two steps. First, the nipple is pushed into the coupling. At the same time, the locking ring must be pulled back to disconnect the coupling. This Safety Feature will make sure that there will be no accidental disconnection.
Complete and safety tested breathing air hose kits
A breathing air hose is no stronger than its weakest link. With a pre-assembled hose kit you will get a complete hose kit where both the components on its own and the complete hose assembly have been thoroughly tested to fulfill and surpass the requirements set for breathing air hoses.
