DN4 (Series 267)

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

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