Ducted Vacuum Inlet extention, 25mm. This fitting is used at the back of ducted vacuum inlet valve to extend the pipe connection that goes into the backing plate.
Why do we need this fitting?
If we change to a thicker floor carpet/tiles, the floor inlet (inlet fitted on the floor) may not reach or seal the backing plate properly. To overcome this, insert this extension between the inlet and the backing plate. You can adjust the length required by trimming the height of the inlet extension.
Suitable for use with ducted vacuum slimline wall inlets.
