Pneumatic Products, Standard Couplings & Nipples

Series 220, DN 5

  • High flow capacity
  • Small external dimensions
  • One-hand operated

Series 220 couplings are suitable for fluid and vacuum applications, as well as compressed air. They offer high flow capacity for a wide range of applications. Safety rings to prevent unintentional disconnection are available on request.


Refer to the CEJN Fluid Products Catalog for specialized versions of Series 220 with brass nipples (Series 221) and two-way shutoff (Series 225). Refer to the CEJN Breathing Air Products Catalog for Series 221 that offers an easy-to-grip locking sleeve.
