Safety Couplings & Nipples

Series 410 Safety, DN 10.4

  • Extremely high flow capacity
  • Full automatic operation
  • Strong and durable

The Series 410 Vented Safety is a universal, pneumatic coupling suitable for a variety of applications. The coupling is an original CEJN design that has become a European standard. It offers high flow and only requires a low connection force, which ensures a safe working environment. The Series is one-hand operated and offers long service life. A wide range of connections is available, as well as anti-hose whip nipples. The Vented Safety version disconnects in two stages in order to vent, minimize the risk of sudden component separation, reduce noise, and prevent recoil accidents. Full automatic operation ensures easy handling. CEJN Vented Safety couplings are compliant with several international safety standards, e.g. ISO Standard 4414 and EN 983 and have a steel front part as standard.


Series 410 is also available in a standard version.
