CoxDENS® PP Flex

The CoxDENS® PP Flex is a flexible PolyPropylene flue gas system, designed for connection to condensing (W) gas or oil fired heating appliances. Ideal for use within service ducts or existing chimney shafts where internal angles or bends figure in the flue route.

Recyclable

At the end of its lifecycle the CoxDENS® PP can be completely recycled. 

Safety

A flexible flue gas system is designed as a vertical flue system installation but is safe to run at angles up to 45° from vertical. In addition, we recommend that the inside of the shaft should be up to 2x the diameter of the pipe to prevent siphon formation. It is also necessary to place a 2 meter bracing bracket (spacer) to prevent premature abrasion wear. If the outside temperature drops below 5 °C, the flexible pipe must be warmed up before installing.
