Stepped Coupling

The Teekay Stepped coupling is a “problem-solver” on any site with the ability to join pipes of different ODs and different materials. Typical applications:

  • refurbishments (where the contractor is connecting a piping system back into the original layout)
  • repairs to old water mains (where the pipe is so corroded it needs to be replaced with a new material in metric size)
  • chamber connections
  • pipe material transitions
  • joining metallic pipe to plastic pipe

Please see below for technical specifications, or contact us to find out more.
