Concentric extension pipe 60/100 mm, 2.0 m, PP 303905

Concentric flue extension pipe 60/100 mm, 2 meters long, made of polypropylene (PP) is an element of a heating installation used to remove exhaust gases from a gas boiler or furnace. It is a product from renowned manufacturers such as Vaillant or Saunier Duval.

One of the most important features of the pipe is its concentric construction, meaning it consists of two layers: an inner layer through which exhaust gases escape and an outer layer which serves as a supply of air to the combustion chamber. This solution allows for high energy efficiency of the heating device and minimizes the risk of failure.

Another important aspect of the extension pipe is its diameter of 60/100 mm. This corresponds to the standard size used in most modern domestic and industrial boiler rooms. It
