The FLEX SDW product range includes double-layered flexible tubes with an inner tube in 904 stainless steel and an outer tube in 316 stainless steel. They are suitable for the installation of abberrant ducts or other difficult to install connections.

Due to the double wall, the inner site of the flexible is smooth, which means that during the combustion process less dirt is created. The FLEX SDW product range is versatile and particularly suitable for intensive use of (condensing) appliances with open combustion, operating in negative pressure.
