150mm-175mm Increasing Adapter – Single Walled Flue Pipe

Also known as a ‘Vitreous Increaser’, this Adapter is perfect for connecting 175mm Single Walled Flue Pipe to a stove with a 150mm outlet diameter.

Intended for internal use only, this uninsulated item is vitreous enamelled inside and out to withstand the temperatures of a woodburner and matches the traditional finish of a stove. The pipe can be cut down from the female end due to its consistent internal diameter but care must be taken as the enamel can chip if cut.

This item features a push-fit male connection and we advise using High Temp. Sealant or Fire Rope (sold separately) to seal.

Available in a traditional matt finish, 100mm-200mm internal diameters.
