Metaloterm MF Adjustable Pipe 60mm-250mm

MF system is a modular twin wall insulated flue/chimney system, made of stainless steel, incorporating a lip seal gasket.  This product is used on top of an existing pipe to offer an exact installation length.  During installation the gasket is removed from the lower pipe allowing the adjustable section to slide within offering a pressure tight seal.

MF is a universal flue/chimney system which is suitable for both high and low temperatures, non-condensing and condensing applications with flue gasses under positive and negative pressure. It is soot fire resistant, therefore the system is suited for a wide range of applications such as boilers, stoves and ovens. The product range also contains a wide variety of silencers.
For Passive houses the assortment provides the Iso-block which can be combined with MF. The system can also be used for CHP applications, in which case a special VITON® sealing ring is used.
Due to its proven quality MF has a 10 year guarantee.
