The DynaKit Basic comes with everything you need to replenish lost, or worn out components for use with your DynaVap unit. The parts found in the DynaKit Basic can be used with just about any DynaVap device on the market today. This affordable kit comes with 2 kinds of O-Rings: 3 condenser O-Rings and 5 High-Temperature O-Rings. If you are in need of new screens or have misplaced your old ones, the DynaKit Basic comes with 3 fresh screens as well. The mouthpiece will not replace the part found on the standard unit, but works well if you use it for a 14mm attachment for a water pipe. DynaWax helps keep your O-Rings lubricated for easily putting the pieces together, and also helps keep the wooden finish of your devices shiny and new. Using the handy pipe cleaners work excellently at cleaning out residue and keeps your device free from buildup. Additionally, the DynaKit basic comes with two plastic storage tubes, just in case you misplaced your other one. The colors of the storage tubes will vary according to what we have in stock when you order.
