Giacomini R978Y226 Polyethylene Water Supply Pipe 16 mm

The Giacomini R978Y226 is a high-performance PE-RT polyethylene pipe specifically engineered for modern heating and cooling systems. This 16 mm diameter pipe features an integrated anti-oxygen barrier, which is essential for maintaining the integrity of closed-loop hydronic systems by preventing oxygen diffusion that can lead to corrosion of metal components. Its robust construction ensures long-term reliability and consistent performance in demanding residential and commercial infrastructure projects.

Advantages

The primary advantage of this pipe is its advanced PE-RT material composition, which offers excellent thermal stability and mechanical strength. The inclusion of an anti-oxygen barrier significantly extends the service life of the entire heating system by protecting boilers, pumps, and valves from oxidative damage. Furthermore, the inherent flexibility of the polyethylene material allows for efficient routing and installation, even in complex layouts, reducing the need for excessive fittings and minimizing the risk of leaks.

Suitable for

• Underfloor heating systems
• Wall and ceiling heating or cooling installations
• Closed-loop hydronic climate control systems
• Renovation projects requiring durable and flexible piping

When it may not be suitable

This product is specifically designed for heating and cooling applications and is classified under application class 4. It is not suitable for the distribution of domestic potable water or high-pressure industrial steam systems.

Key specifications

• Material: PE-RT polyethylene
• Inner diameter: 16 mm
• Integrated anti-oxygen barrier
• Application class: 4
• Designed for heating and cooling systems

How to use

Installation should be performed by qualified professionals in accordance with local plumbing and heating standards. The pipe can be unrolled and secured using appropriate clips or mounting rails designed for underfloor heating systems. Ensure that the minimum bending radius is respected during installation to prevent kinking or structural stress. Connections should be made using compatible fittings specifically designed for this pipe diameter and material type to ensure a secure, leak-proof seal.

What to consider before purchase

• Verify the compatibility of the pipe diameter with your existing manifold and fitting system.
• Ensure the application is strictly for heating or cooling, as this pipe is not intended for potable water.
• Calculate the total length required for your specific floor area to minimize unnecessary joints.

Usage recommendations: Always perform a pressure test on the completed installation before covering the pipes with screed or flooring materials to ensure all connections are properly sealed and the system is fully operational.
