Our General Purpose Water Discharge Hose. If you’re looking for a low pressure discharge hose that will move water from one place to the next, Vinylflow is your best bet! Vinylflow's construction consists of a balanced polyester yarn spiral wrap that is enhanced with a longitudinal strength member, which then is surrounded by a PVC homogenous tube and cover. Vinylflow coils flat for easy storage and has ultraviolet inhibitors to reduce aging and weather checking. The smooth inner lining provides for low friction loss. Hose is blue in color.
