I'm looking for a source for unsalted soft plastic tubes sized 3.5 to 5 inches for building my own Rizzo Wiz inline spinners. Most tubes are salted and they present a corrosion issue due to the impregnated salt. Zoom used to sell such tubes 10-15 years ago but it looks as though they are discontinued. I'm looking for the colors hot yellow, pearl white, red and black. Any help in sourcing is much appreciated.
