This FREE 150mm long x 50mm diam Flexible Hose & 1 Roll PVC Tape will only be supplied if you buy a power unit (any power unit from our online shop).
Use this flexible hose to connect power unit to the pipework (instead of using PVC pipes). This hose has a smooth internal surface which won't restrict the air flow. It will also make the job to fit a power unit much easier.
Note: you will not need this product if you already get free power unit fit off kit.
Tips: Do not glue the pipe or fitting to the machine to allow for easy removal in the future. Just tape it up with an electrical tape provided.
