The 1000mm STRAIGHT LENGTH of Vitreous Enamelled flue is the longest length of single wall pipe and is ideal for connecting a stove to your Twin Wall or Flexible Flue installation (with the appropriate adaptor). These parts receive a coating of enamel to match the traditional aesthetic of a wood burning or multi-fuel stove and to guarantee the resistance of the finish even at very high temperatures. Connection Vitreous Enamelled flue parts have a male connection to push fit inside the pipe or stove outlet below to ensure deposits within the pipes run down into the stove and do not escape. The male connection is always fitted facing downwards as pictured. It is advisable to seal all single wall joints with a suitable high temperature sealant. It is not advisable to cut this single wall pipe down to size.
