Fluid Products, Classic Couplings & Nipples

Series 225

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


Requiring only one hand for operation, Series 225 couplings are suitable for a variety of fluid applications, such as water inlet and return for injection molding lines. Series 225 features both valved couplings and valved nipples. Other sealing materials, such as Viton® and EPDM, are available on request. Straight-through couplings are also available upon request.
