Vitreous Enamel steel pipe matt only has a male end and no female end. The male end must be installed facing downwards. Due to only having one tapered end this pipe can be easily cut and still used within a system, with the male end from the second piece going inside the cut end of the first piece. 

Adjustable pipes are used to achieve specific flue lengths. If fitted close to the appliance this will enable the appliance to be removed without having to dismantle the flue. 

Please be aware!!!

Although classed as an adjustable length,
this product is just a slightly undersized length,
which allows it to slide inside a normal fixed length of stove pipe.
Therefore you must order a normal fixed length of stove pipe with this product in order for it to work!

Stove pipe one piece off sets are used when you need to offset the stove pipe to enter the chimney. 

The Vitreous enamelled one piece offset connects to a flexible flue liner using an adapter.
