👉 The single-wall to twin-wall insulated adapter is an essential component for a tight, secure connection between the rigid connecting flue pipe of the heating appliance and the twin-wall insulated chimney flue.
Its clever design allows the stove pipe to be fitted and removed easily: on the stove side, the (Male) connector is 375 mm high in twin wall, which allows the rigid pipe to be pushed up inside it so it can be removed, cleaned and refitted easily. With this type of connector, a sliding stove pipe is no longer needed!
➡️ For a flawless finish, we recommend combining this connector with the black finishing rosette 0° or the black rosette in 2 parts 1 to 10° (or other angles).
⚠️ Bofill insulated twin-wall flue accessories may be compatible with other brands of flue provided they have the same internal / external dimensions.
