Expansion Ring Fittings


Alimentary use
Cold water 0ºC to 15ºC
Underfloor heating
Radiators system heating
Sanitary hot water
Drinking water

Expansion Ring Fittings:

  • Expansion Ring fittings are developed based on a method where a PEXa and PEXa EVOH pipes are gradually expanded with a special ring fitted on the outside, and then allowing it to shrink back onto a fitting nipple.
  • Made of PPSU (Polyphenylsulfone) and CW617N brass, compatible with PEXa and PEXa EVOH pipes.
  • Range: Ø 16 to Ø 32 mm.
  • Colors: Black body and Blue + Red rings.
  • Maximum temperature: 95º C.
  • * Other brass alloys on request (602N DZR – CW511…).
