DN10 (Series 981)


  • Self-sealing couplings
  • Generous misalignment capability
  • Easy installation



CEJN Series 981 is part of CEJN's range of compressed air couplings for automation. The range is intended for use in manifold connections systems for transferring compressed air and other media. The unique feature of this coupling is its valve design, which allows the coupling to seal against a mating block. The nipples are also included in the range for use when double shut-off is required. Series 981 is suitable for a variety of applications such as transfer presses, tool-changing systems, pneumatic connections on palletizing equipment, plastic injection molding machines, robotics and automated connections of airlines.


The Series is also available in two other sizes: Series 961 and 971.
