With unlimited combination possibilities, CEJN Series 567 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 567 is also available with color-coding and/or key coding for extra safety. Optional seal material upon request.
