This economic screw joint system was developed especially for tubing made of PTFEGlossaryPTFE Polytetrafluoroethylene , PFAGlossaryPFA Perfluoroalkoxy or FEPGlossaryFEPTetraflouroethylene-Perflouropropylene, but it can also be used with tubes made of glass or steel. Its function is based on compression rings which provide a pressure resistance of up to 5 bar at room temperature. All parts which are exposed to the medium are made of PTFEGlossaryPTFE Polytetrafluoroethylene . Only the nut which is not in contact with the medium is made of glass-fibre reinforced PTFEGlossaryPTFE Polytetrafluoroethylene for better stability. The fittings and nuts have metricGlossarymetric The metric system is an international decimalised system of measurement. In Europe, the system was introduced in the 19th century to achieve international comparability.

All components of this system have a universal chemical resistance, since the product is only exposed to PTFEGlossaryPTFE Polytetrafluoroethylene .
