ARCO PEX/AL/PEX Multilayer Pipe 18x2 mm

The ARCO PEX/AL/PEX multilayer pipe with an 18x2 mm diameter is a high-quality composite solution engineered for modern plumbing and heating systems. By integrating a core layer of aluminum between layers of cross-linked polyethylene, this pipe offers a unique combination of flexibility and structural integrity. It is designed to withstand demanding conditions while maintaining consistent performance in both residential and commercial water distribution networks.

Advantages

The primary benefit of this multilayer pipe is its exceptional durability and resistance to corrosion and scaling. The aluminum core acts as an oxygen barrier, which significantly reduces the risk of oxidation in heating components and prevents the pipe from sagging over time. Its inherent flexibility allows for easier installation around corners and obstacles without the need for excessive fittings, which minimizes the potential for leaks and reduces overall installation time. Furthermore, the pipe maintains its shape once bent, providing a clean and professional finish to any piping layout.

Suitable for

• Residential hot and cold water supply systems
• Radiant floor heating installations
• Commercial plumbing infrastructure
• Renovation projects requiring durable and flexible piping

This pipe may not be suitable for high-pressure industrial steam applications or systems where temperatures consistently exceed the manufacturer's thermal limits. It is also not intended for use in environments exposed to direct, prolonged UV radiation, as the outer polyethylene layer may degrade over time if not properly protected or insulated.

Key specifications

• Outer diameter: 18 mm
• Wall thickness: 2 mm
• Material composition: Polyethylene and Aluminum
• Working pressure: 9.8 atm
• Flexibility: High
• Color: White
• Total length: 200 m

How to use

Installation should be performed using compatible press or compression fittings designed specifically for multilayer pipes. Ensure that the pipe ends are cut squarely and deburred properly before insertion into the fitting to prevent damage to the internal O-rings. When bending the pipe, use a suitable bending spring or tool to prevent kinking, especially when working in tight spaces. Once installed, the system should be pressure-tested according to local building codes to ensure all connections are secure before the pipes are concealed within walls or floors.

What to consider before purchase

• Verify that the 18 mm diameter is compatible with your existing system requirements
• Ensure you have the correct tools for cutting and bending multilayer pipes
• Check that your chosen fittings are certified for use with PEX/AL/PEX composite materials
• Confirm the total length of 200 meters is sufficient for your project scope

Usage recommendations: Always store the pipe in a cool, dry place away from direct sunlight. Avoid dragging the pipe over sharp edges or abrasive surfaces during installation to maintain the integrity of the outer protective layer.
