Multi & Auto Products, Auto-Couplings Fluids

DN 15 (Series 974)

  • Minimizes downtime
  • For a wide variety of media
  • Non-Drip design

CEJN Fluid auto-couplings/blind-mate couplings are specially designed for industrial automation. When used as manufacturing connections, they can minimize costly downtimes due to repair-work or during mold and tool changes. CEJN Auto-Couplings built into manifolds allow fast, simultaneous connection and disconnection of an unlimited number of lines for a wide variety of media. The unique patented design enables the couplings to be connected/disconnected under full working pressure. The high performing couplings and nipples have a working pressure of up to 507 PSI (35 bar) and their Flat-Face, Non-Drip design ensures leak-free performance. Series 974 is made of nickel-plated brass and is suitable for fluid / cooling applications such as tool changing systems on machine equipment. The Series has a wide selection of thread connections where G are available as standard. There are alternative ways of mounting by using separate thread connections. Special models using other materials are available on request.

The Series is also available in five other sizes: Series 864, 924, 944, 964 and 984. Steel versions available as series 915, 925, 945, 965, 975 and 985.
