Wall penetration for DN350/250, 500mm 2651415

Wall penetration for flue gas exhaust systems

The penetration is made of stainless steel with an inner polypropylene pipe, ensuring corrosion resistance and high thermal stability during operation in humid or aggressive conditions. The design allows for both external and internal installation – no change in installation method is required depending on the wall penetration location.

The 500 mm length is adapted to standard wall thicknesses in residential and commercial construction, enabling passage through concrete, brick, or other materials without additional adjustments. The outer diameter of 350 mm and inner diameter of 250 mm correspond to the parameters of typical concentric flue gas ducts – no adaptation to other diameters is required.

No additional gaskets or thermal insulation are needed during installation – the material and construction form provide natural insulation and sealing. Installation is simple: the element is inserted into the wall opening, and the flue gas duct is passed through the center – no precise calculations or specialized tools are required.

Compliant with requirements for flue gas exhaust systems for gas and district heating boilers, with no additional requirements regarding pressure or temperature – operates stably under standard operating conditions of domestic installations.
