Fluid Products, Classic Couplings & nipples

Series 414

  • Low connection force
  • High-flow capacity
  • Small external dimensions

Series 414 includes a two-way shut-off and is connectable with Series 411 valveless nipples. Requiring only one hand for operation, Series 414 couplings are suitable for a variety of fluid applications, such as water inlet and return for injection molding lines. Dust caps are included as standard. Viton® and EPDM sealings are available on request.

The Series is also available with brass nipples (Series 411), high-pressure straight-through (Series 412), 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).
