Fluid Products, Classic Couplings & nipples

Series 411

  • One-hand operated
  • Extremely high-flow capacity
  • Large range of connections

Series 411 features valved couplings and valveless nipples. Requiring only one hand for operation, the Series is suitable for a variety of fluid applications, such as water inlet and return for injection molding lines.


The Series is also available in a high-pressure straight-through design (Series 412), two-way shut-off (Series 414), and stainless steel construction (Series 416). Please refer to the CEJN Pneumatic range for specialized versions of the Series with nickel-plated steel/brass construction and as Vented Safety (Series 410).
