There was a previous post regarding non-Festool hoses. I picked up a 36mm, blue hose from Lowes for around $30.00 to use with my Kapex. It fits perfectly to both the vac and saw. Also, as a bonus there are some additional fittings in the box. One of which is a 1.25 to 1.5 coupler perfect for fitting the Kreg Jig to the Festool 27mm hose. Works great plus you get two for one.
