Reducer

expansion joint

The Rubber Reducer Expansion Joint combines the functionality of a reducer and a flexible joint. Constructed from reinforced elastomer with tire cord and steel wire, it accommodates axial, lateral, and angular movements while reducing or increasing pipe diameters. This dual purpose makes it ideal for space-saving pipeline transitions in pump connections and industrial piping. Typically supplied with flanged ends (concentric or eccentric), depending on system requirements.

  • Size Range (DN)

    DN25 – DN1000 (larger/custom sizes on request)

  • Materials (Elastomer)

    Natural Rubber, EPDM, Nitrile, Neoprene, Hypalon

  • Reinforcement

    Nylon tire cord with steel wire

  • Movements

    Axial, Lateral & Angular

  • Pressure Rating

    PN10 – PN16 (up to PN25 on request)

  • Temperature Range

    –20°C to +120°C (up to +150°C with special elastomers)
