Valves and fittings in steel and cast iron

A range of special ranger couplings, designed with a central polyetylene sleeve, suitable to combine pipes of different diameters and materials such as stainless steel, cement, asbestos, PVC, PE, fiberglass, ductile iron. Hydraulic couplings are available in different telorance ranges and lengths. Using polyetylene in these special ranger couplings, allows to convey aggressive medium fluids (industrial, sewers, sea water...). Also a further version is available for severe applications: with an outer stainless steel sheet on the central PE sleeve. 

Our range includes

  • Universal hydraulic couplings, with central PE sleeve - PN 16: with the same tolerance range on both pipe sides, they combine pipes of different materials and sizes going from Ø 46 mm up to Ø 270 mm.
  • Reduced hydraulic couplings, with central PE sleeve - PN 16: different tolerance range on each pipe side, it delivers great adaptability, up to 50 mm.
  • Long hydraulic couplings, with central PE sleeve - PN 16: with the same tolerance range on both pipe sides, they combine pipes of different material and sizes, going from Ø 46 mm to 270 mm. The central sleeve in this case is much more longer, from 270 to 500 mm, for installation on slopes and hills, in case of landslide risk or pipeline subjected to thermal expansion or contraction.

For all sizes and tolerances range, please see our catalogues.
