Restrained non-concentric pipe coupling RRS-MIM-E



Intended for mechanical connection of plain ends of pipes shifted axially with each other of equal or different diameters in waterworks, wastewater and other systems for liquids chemically neutral. Equipped with rims protecting againt sliding pipes out of a coupling. Used for iron, steel, plastic, GRP and AC pipes.


  • diameter range 270-1200 mm
  • coupling tolerance is ± 7 mm in relation to the outer pipe diameter
  • pipe angular deflection up to ± 3°
  • corrosion protection:
    – epoxy coating
    – optional: hot-dip galvanized
  • EPDM gasket for potable water or NBR gasket for wastewater
  • threaded galvanized pins,
    optional: hot-dip galvanized, stainless steel, acidresistant steel
  • eyebolt
  • possibility to design and produce a coupling according to individual customer needs: nonstandard height, made of different materials, e.g. stainless steel
  • possibility of connecting different types of pipes shifted axially in relation to each other
  • prevents pipes from sliding out of a coupling
  • the design of protection depends on the pipe material and pressure
