CEJN® Series 322 Couplings - Industrial Ancillaries

CEJN® Series 322 Couplings

  • Series 322 offers a high working pressure rating and high-flow capacity, making it ideal for high-pressure water applications, such as high-pressure cleaning lines. Available with valved or valveless couplings, the series requires only one hand for operation – just one of the reasons why this original CEJN series continues to be requested. Other connections and sealing materials are available on request.

  • One-hand operated

  • High burst/working pressure

  • Extremely high-flow capacity
