Cejn 320 Series Pneumatic Couplers & Fittings

Cejn 320 Series Pneumatic Couplers & Fittings

Series 320 couplings feature the original high-flow valve design upon which all other CEJN pneumatic couplings are based. 

  • Their popularity has made Series 320 a European standard
  • The Series is easy-to-handle and one-hand operated and offers long service life
  • Male threads on the couplings and nipples feature pre-applied thread sealant
  • The Series 320 vented safety version is disconnected in two stages in order to vent the coupling and minimise the risk of sudden component separation, which has the potential to cause operator injury
  • FuIly automatic operation ensures easy handling
  • The vented safety version complies with ISO Standard 4414 and EN 983
