About atoll Dichtungstechnik
atoll Dichtungstechnik is a Swiss company based in Kreuzlingen on Lake Constance, owned by Dipl.-Ing. Ipek Stumpf. The company specialises in metallic seals, including ring joint gaskets, spiral wound gaskets, kammprofile gaskets, metallic flat gaskets, lens gaskets, insert and backing rings, packing rings and spike-edge gaskets. In addition, non-metallic flat gaskets based on graphite, fibre or PTFE are offered. Custom and one-off productions are possible from a single piece, from precision gaskets to special productions with 3000 mm diameter; thanks to a large stock, short-notice deliveries are possible in emergencies. The company holds the general distribution rights for Switzerland, Austria and Italy and sources its products from a long-established manufacturer with its own production plant in Germany. In addition, atoll Dichtungstechnik operates as a globally active trader of seamless and welded steel pipes, hollow sections, round steel and square steel pipes. The products are used in mechanical engineering, plant engineering, piping construction as well as in the pharmaceutical and petrochemical industries, in refineries and power plants.
