TKST stepped coupling

Teekay Stepped Coupling

The Teekay Stepped coupling is a "problem-solver" on any site with the ability to join pipes

of different O.D.´s and different materials.

Typical applications

- refurbishments (where the contractor is connecting a piping system back into the

original layout).

- repairs the 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.

Sizes

48,3mm to 3.000 mm

The table below is a guide to the most common sizes. Couplings to suit specific outside

diameters not listed may be manufactured to order.
