CEJN® Series 300 Safety Couplings - Industrial Ancillaries

CEJN® Series 300 Safety Couplings

  • The CEJN Series 300 Safety vented coupling is a universal, pneumatic coupling suitable for a variety of applications. It offers high flow and only requires a low connection force, which ensures a safe working environment. Male threads on the couplings and nipples feature pre-applied thread sealant. 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 Series 300 Vented Safety couplings are compliant with several international safety standards, e.g. ISO Standard 4414 and EN 983.

  • Series 300 Vented Safety couplings are also available in Standard, Soft-Line and Multi-Link versions.
