Can I use any hose for my PLANEX Sander?

The correct hose to use for the PLANEX sander is part number 577101. The connector has a distinctive fit and will only fit on the Planex sander, the connector locks the hose into position so it can't fall off when operating.
There is a PLANEX dust extraction adaptor will take any 27mm or 36mm hose in the Festool range.
