The Triplelock Adaptor to Single Wall - ø 300 is an essential component for those installing or retrofitting gas flue systems. This adaptor serves as a secure termination point where a gas terminal (GC1) is required for gas-fired appliances. Engineered for precision and durability, the adaptor fits over a protruding liner and can be secured using a stainless steel screw, ensuring a firm and weather-resistant seal.

During installation, we recommend using an acid-resistant cement to enhance the seal and provide extra protection against the elements. For optimal performance and safety, it's crucial to maintain your chimney by sweeping it annually or more frequently if needed, particularly when serving gas and oil appliances.

For optimal performance, first ensure the chimney is clean and free of debris. Position the adaptor over the protruding liner at the apex of your chimney. Secure it firmly using a stainless steel screw, then apply a generous layer of acid-resistant cement around the joint to create a weather-proof seal. It is vital that the sealant fully encases the connection to protect against moisture and external elements. We recommend scheduling an annual inspection and sweep of your chimney, especially if the system serves gas or oil appliances, to maintain its efficiency and safety.

This adaptor is specifically designed for gas-fired appliances requiring a GC1 gas terminal for termination.

Place the adaptor over the protruding liner, secure it with a stainless steel screw, and use acid-resistant cement to seal and weather-proof the connection.

Yes, when installed correctly with suitable cement, the adaptor provides a durable weather-resistant seal.

Chimneys serving gas and oil appliances should be swept and maintained at least once a year or more frequently if necessary.

The Triplelock Adaptor is specifically designed for gas-fired flues and may not be suitable for other types of flue systems.

A standard screwdriver for the stainless steel screw and tools for applying cement are typically required.

This adaptor is designed for a flue with a diameter of 300mm (12 inches).
