The Screw fit Long Tail Flex Adapter is used to connect the flexi liner to a single wall flue pipe.

Available for either a five inch – 125mm or a six inch – 150mm flue, the Long Tail Flex Adapter is a easy to use connection. Made from 316 grade stainless steel, it has a pressed thread that allows it to be screwed to Quattro Flue Liner giving a gas tight seal. It has integral drain holes to let the condensates flow back into the flue.

The installation process has been laid out by our team. We recommended installation is only done by a trained tradesman. Instructions can be found in the tab below. It is recommended that chimneys serving solid fuel appliances be swept and maintained as frequently as necessary but at least once a year. This helps to maintain a healthy burning inside your stove. Ensuring your equipment lasts longer.

Connect the bottom of the Flue Liner to the adaptors twin wall section by screwing the adaptor on to the Flue Liner as you would an ordinary nut and bolt, you can apply a small amount of High Temperature Silicone Sealant to ensure a gas tight connection.

You can now conect the Adaptor using Fire Cement or High Temperature Silicone Sealant to either your appliance (if the appliance is a solid fuel appliance then you must have a least 600mm of flue pipe before this connection) or Black Pipe / Vitreous Enamel / Single Wall Stove Pipe.

If the gap is large between the Adaptor and the pipe you can seal using a combination of Fire Cement / Silicone and Fire Rope. Because this end is 200mm long it allows you use it as a extendable pipe which can be cut down as necessary.
