Schiedel Prima smooth 316 grade stainless steel flue pipe 125mm (5”) diameter. This is an off cut 370mm so has no spigot but will fit in to a flue spigot, other lengths or bends of Prima smooth will fit into the top. This is for internal use and must be at least 3 times it’s diameter from combustible material (375mm). This is new as if it’s never been used or fitted, but is an off cut. Postage 2nd class signed for or collection weekends or evenings only. Thank you for looking.
