  • Offer Profile
  • Plastic valves, pipes and fittings for industrial piping systems.

    Two core areas of expertise make us strong.

    The first of these consists of special products in the area of valves, pipes and fittings. The second is the unmatched knowledge in the processing of plastics that we have acquired over almost five decades. You too, can profit from this knowledge by means of our unique contract manufacturing service, developing individual customer solutions.

    We are very proud of these areas of expertise.
