This 316 grade stainless steel Single to Twin Adaptor is used to connect 6″ single wall vitreous flue pipe to 6″ twin wall flue pipe. We recommend purchasing the embellisher with this item. The Embellisher is designed to slide over the top of the Single to Twin Adaptor, where it connects to twin wall flue pipe. This is purely for aesthetic reasons so that it provides a neat finish at the point of connection, with no insulation showing. Made from 316 grade stainless steel. 30mm high grade insulation promotes efficient performance and protects against the build up of condensates within the flue system. All twin wall flue components are CE approved. There is only a 50mm clearance from combustible materials needed when using our twin wall flue. Every twin wall flue component is supplied as standard in stainless steel however we do offer a powder coating service to RAL colours for an additional cost, which allows the components to be supplied to you in a range of different colours to better suit your property. Please contact us for more information regarding this service.
