Key Features and Their Benefits
High-Quality Material: Made from 316L stainless steel, the adaptor promises longevity and strength, making it resistant to corrosion and able to withstand high temperatures. This durability is essential for both domestic and commercial applications, safeguarding your investment for years to come.
Versatility in Application: Whether your system is condensing or non-condensing, this adaptor is designed for both.

This wide range of applications simplifies your purchasing decisions by reducing the need to stock multiple components.
Ease of Installation: The innovative push-fit jointing system and secure locking band ensure that the adaptor is easy to install, providing a reliable and leak-free connection. For installers, this means faster setup times and fewer callbacks due to installation errors.
Enhanced Safety: With the inclusion of a high-pressure sealing gasket (P1/H1) and compliance with EN 1856-1 standards, this adaptor assures safe use. Maintaining a safe distance of 50mm from combustible materials adds an extra layer of protection, making it perfect for sensitive environments.
Installation and Safety Guidelines
Proper installation is critical for the optimal performance of your heating system. For P1 and H1 installations, it is imperative that jointing gaskets are applied at every connection point. This not only ensures a tight fit but also maximises the efficiency of the sealing process. Always maintain the recommended 50mm distance from combustible materials such as wood or plasterboard.
When installing the adaptor in a condensing appliance setup, it is advisable to apply silicone sealant between the adaptor and the appliance outlet unless your system comes with a built-in seal. This additional sealing step helps prevent potential leaks and enhances the overall safety of your installation.
