DN19 (Series 767)

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

With unlimited combination possibilities, CEJN Series 767 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 767 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 267, 467, 567 and 667. Please refer to Series 777 for a stainless steel version. For other sizes in stainless steel, refer to Series 277, 477, 577 and 677.
