Teekay Stepped Coupling

The Teekay Stepped coupling is a "problem-solver" on every construction site. Various

materials and pipe diameters can be interconnected. Due to this high efficiency, it has a

great saving potential on site.

Typical applications

- Connections of steel pipes with plastic pipes or concrete with GRP

- Repairs of old lines in the DIN area with new ISO dimensions

- Shaft connection

Dimension range

The listed dimensions are guides to the most common sizes. Couplings of other diameters can

also be made.
