CEJN® Series 115 Couplings

  • CEJN Series 115 couplings are available in both standard and Flat-Face designs.
  • The 115 Series is a CEJN original with extremely small outside dimensions.
  • Non-drip connection and disconnection are standard on the CEJN High-Pressure range.
  • All exposed components are made of zinc-plated steel.
  • The coupling is also available in a design with a safety ring for the locking sleeve to prevent accidental disconnection.
  • Plastic dust caps are standard on both coupling and nipple, dust caps of aluminium can be ordered separately. The nipple is also available in a design with a hose rupture valve.
  • In the event of a ruptured hose the nipple closes and prevents the system from being drained of oil, which could have critical consequences for production and the environment.
