the classic coupling

  • NOMIC DUO, our classic coupling with millions already installed, typified by its unrivalled technical advantages:
  • All around rim, even in the area between the fixing, protects the rubber gasket against
    mechanical damage, UV-radiation and ozone. The fixing parts fulfil
    the increased resistance to corrosion according to DIN EN 877.
  • High sealing lips allow easy installation of the complete coupling, covering even large pipe
    tolerances.
  • The EPDM gasket is resistant to boiling water.
  • No welding points in the tension loaded areas.
  • An extra thick center lip prevents the transmission of structure-born noise.
  • Ready-to-use unit – no loose pieces.
  • A very quick and economical installation with the revolutionary NOMIC DUOMAT tool.
  • Upgrade option – fixing plates and screws are available in A4 stainless steel on all couplings.
