Technical Data

    The SFL Sflue increasing adaptor from single to twin wall takes you from 4 inch single wall up to 5 inch twin wall pipe in one go. It is the first twin wall flue part you will need for your twin wall flue installation. It connects directly to your stove spigot and then upwards to your twin wall pipes or to the length of enamelled pipe coming out of the top of your stove. It is usually recommended to come straight out of the stove with a length of enamel pipe as this pipe is both cheaper and harder wearing.

    Please note - as with all twin wall parts the diameter quoted is the internal diameter - the external diameter is 2 inches larger due to the surrounding insulation.
