extended product description

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.

Operating pressure

The specified operating pressures are designed for steel pipes. The minimum wall thickness

please refer to DIN 86128 Part I and II.

The strength calculation in the industrial sector is 1.5 time.
