Series 702, DN25 Stainless Steel

  • Valveless design provides unrestricted flow
  • Colour-coded rings help to avoid mixing of media
  • Robust design to withstand long term, repeated use

CEJN series 702 stainless steel connectors in DN25 are an economic and efficient quick disconnect coupling that permit unrestricted high flow and accommodate high viscosity fluids for larger fluid and pneumatic lines in cooling of electronics. The straightforward design reduces pressure drop to reach the maximum flow at low costs. The series offers long service life in low-pressure applications, such as fluid transfer, coolant/heating, chemical processing, and vacuum service. Series 702 is reliable and easily installed and operated. Visual difference is obtained by adding colour-coded rings and, for extra safety protection, a safety-locking device is optional.

Available in two other sizes: please refer to 852 and 922. The series is also available in brass. See series 701, 851 and 921.
