  • Non-Drip design
  • Unlimited combination possibilities
  • Different safety levels to avoid mixing media

With unlimited combination possibilities, CEJN Series 477 non-drip modular couplings are adaptable to virtually all applications and system requirements. The Non-Drip design of the Series ensures practically zero spillage and eliminates pollution and air inclusion during connection and disconnection. The Series is available in three configurations: straight through, single shut-off and double shut-off. Series 477 is also available with color-coding and/or key coding for extra safety. Optional seal material upon request.


The Series is also available in four other sizes: Series 277, 577, 677 and 777. Please refer to Series 467 for an all brass version. For other sizes in brass, refer to Series 267, 567, 667 and 767.
