Automatic safety locking feature
Double seal function for extra safety
Cross connection between series is impossible
Series 181 is specially designed for gas applications with a high flow valve. Like most other CEJN couplings, this series offers one-hand-operated connection, an integrated safety feature that prevents unintentional disconnection and a color coded (blue) locking sleeve and nipple. Couplings and nipples with female thread connection features an internal sealing cone. The part number for dust caps are 09 171 1000 for couplings and 09 171 1050 for nipples.
Conversion factors for the flow from air to other gases:
Acetylene = Air flow x 1,05
Oxygen gas = Air flow x 0,95
Nitrogen = Air flow x 1,02
Lp-gas = Air flow x 0,81
Town gas = Air flow x 1,49
Nominal flow diameter: 5 mm (")
Air flow: 720 l/min (25.4 CFM)
Max. working pressure: 10 bar (145 PSI)
Min. burst pressure: 40 bar (580 PSI)
Temperature range: -30°C — +100°C (-22°F — +212°F)
Material coupling: Yellow pickled brass/aluminium. Seal material EPDM
Material nipple: Yellow pickled brass/aluminium.
Flow capacity is measured at 6 bar (87 PSI) inlet pressure, and pressure drop at 0.5 bar (7 PSI).
