Peek tubes
Tubes made of polyaryletheretherketone, or PEEK 
        for short, are distinguished above all by a particularly high degree of 
        hardness and a reliable resistance to chemicals. Because of these properties 
        PEEK tubing is mainly used for high-pressure requirements and laboratory 
        applications. The basic colour of PEEK is medium brown to grey. 
        However, by adding colouring agents the hoses can be produced in various 
        colours on request. Coloured 'bar codes' can also be applied to the PEEK 
        tubes to mark certain standard sizes. 
        Where the chemical resistance of PEEK tubing does not meet our customer's 
        requirements, a two-layer design can be provided for. In that case, a 
        tube made of Teflon® PTFE is applied to the inside of the outer PEEK hose. 
        This construction guarantees maximum resistance to chemicals inside the 
        tube, combined with an excellent resistance to pressure.
        Its name: FLUORTEK DUOLINE.
