M12x1 Connectors over-molded with plastic coupling screw/nut

The M12x1 product portfolio of over-molded connectors has been expanded by a new variant. In addition to the previously existing versions with screw elements made of zinc die cast and turned stainless steel 1.4404, a version with plastic screw elements has been added.

The screw elements are made of PA6 GF20 UL94-V0. As the plastic materials are resistant to weak acids, bases, alkalis and alkaline cleaning agents, the scope of application is where the chemical environment allows no use of zinc die-cast fittings and where stainless steel elements are too expensive.

Typical examples include dosing pumps for the treatment of drinking water, wastewater and industrial water, metering equipment and disinfection systems for the industrial use of, for example,  electroplating as well as for applications in the agricultural sector.


  • Good grip of the screw elements
  • Good chemical resistance of the connector
  • High protection class

Fields of application:

  • Chemical industry
  • Agricultural and construction machinery
  • Food industry
  • Municipal equipment
