## Summary description

The K-flex PERT/AL/PERT multilayer pipe, size 16x2.0mm, is a high-quality composite piping solution designed for heating and plumbing systems. Featuring a 50-meter length, this pipe combines the flexibility of PERT with the structural integrity of an aluminum layer, ensuring excellent thermal resistance and oxygen barrier properties. It is ideal for underfloor heating and radiator connections, providing durability and ease of installation for professional applications.

## Long description

The K-flex PERT/AL/PERT multilayer pipe, with a dimension of 16x2.0mm and a total length of 50 meters, is a high-performance composite piping solution engineered for modern heating and plumbing installations. This pipe features a multi-layer construction that integrates the flexibility of polyethylene of raised temperature resistance (PERT) with a central aluminum core, providing a robust and reliable conduit for water-based systems. The red-colored outer layer ensures easy identification during installation, while the aluminum layer acts as a highly effective oxygen barrier, preventing corrosion in metal components of the heating system.
Advantages
This multilayer pipe offers exceptional durability and thermal resistance, making it a superior choice for demanding environments. The inclusion of an aluminum layer provides excellent dimensional stability and reduces thermal expansion, which is critical for maintaining the integrity of heating circuits over time. Its inherent flexibility allows for easy bending and routing around obstacles without the need for excessive fittings, significantly reducing installation time and the risk of potential leak points. Furthermore, the smooth inner surface minimizes pressure loss and prevents the buildup of scale, ensuring consistent flow rates throughout the lifespan of the system.
Suitable for
Underfloor heating systems
Radiator connection piping
Domestic hot and cold water plumbing
Renovation projects requiring flexible routing
This pipe may not be suitable for applications involving exposure to direct sunlight for extended periods, as the outer material is not UV-stabilized. It is also not intended for use in high-pressure steam systems or environments where temperatures consistently exceed the manufacturer's specified thermal limits.
Key specifications
Outer diameter: 16 mm
Wall thickness: 2.0 mm
Total length: 50 m
Material: PERT/Aluminum/PERT composite
Color: Red
Flexibility: High
How to use
The pipe should be uncoiled carefully to avoid kinking. Use appropriate pipe cutters to achieve a clean, square cut before inserting the pipe into compatible press or compression fittings. Ensure that the pipe end is properly deburred and calibrated to prevent damage to the O-rings within the fittings. When bending the pipe, use a suitable bending spring or tool to maintain the circular cross-section and prevent structural stress.
What to consider before purchase
Verify the compatibility of your existing fittings with 16x2.0mm multilayer pipes.
Ensure the pipe length of 50 meters is sufficient for your specific circuit layout.
Check the maximum operating temperature and pressure requirements of your heating system.
Usage recommendations: Always follow local building codes and manufacturer guidelines regarding minimum bending radii to ensure the longevity and safety of your plumbing or heating installation.
