K-flex PERT/AL/PERT Multilayer Pipe 20x2.0mm 50m

The K-flex PERT/AL/PERT multilayer pipe 20x2.0mm is a high-quality composite solution designed for modern heating and plumbing systems. By combining the flexibility of polyethylene of raised temperature resistance (PERT) with the structural stability of an aluminum core, this pipe provides a reliable and long-lasting infrastructure for fluid transport. The 50-meter coil length ensures efficient installation with fewer joints, reducing the risk of leaks in residential and commercial piping networks.

Advantages

This multilayer pipe offers exceptional durability and resistance to corrosion, ensuring a long service life even under demanding operating conditions. The integrated aluminum layer significantly reduces thermal expansion compared to standard plastic pipes, maintaining the integrity of the system during temperature fluctuations. Its inherent flexibility allows for easy bending and routing around obstacles, which simplifies the installation process and reduces the need for additional fittings. The smooth inner surface minimizes pressure loss and prevents the buildup of deposits, promoting efficient flow throughout the system.

Suitable for

• Underfloor heating systems
• Radiator heating connections
• Hot and cold water supply networks
• Renovation of existing plumbing infrastructure

This pipe may not be suitable for applications involving exposure to direct sunlight for extended periods, as UV radiation can degrade the outer material. It is also not intended for use in systems where operating temperatures or pressures consistently exceed the manufacturer's specified technical limits.

Key specifications

• Outer diameter: 20 mm
• Wall thickness: 2.0 mm
• Total length: 50 m
• Material composition: PERT and Aluminum
• Color: Red
• Flexibility: High

How to use

To install the K-flex multilayer pipe, ensure the surface is clean and free of sharp objects that could damage the outer layer. Use appropriate pipe cutters to achieve a clean, square cut at the desired length. When bending the pipe, use a bending spring or a pipe bender to prevent kinking and maintain the internal diameter. Secure the pipe using compatible fittings designed for multilayer systems, ensuring that all connections are tightened according to the manufacturer's torque specifications to guarantee a watertight seal.

What to consider before purchase

• Verify the compatibility of your existing fittings with 20mm multilayer pipes.
• Ensure the pipe specifications meet the pressure and temperature requirements of your specific heating or plumbing project.
• Consider the total length needed for your installation to minimize waste.

Usage recommendations

Always perform a pressure test on the completed system before concealing the pipes behind walls or under floor screeds to ensure all connections are secure and leak-free.
