Abstract
The present disclosure provides a self-draining hose. The self-draining hose includes a flexible hose connected to an inlet end fitting and an outlet end fitting and defines a fluid passage through the flexible hose. The flexible hose is made from an elastomer material having a memory with a cross-sectional flat profile defining a collapsed position closing the fluid passage, and has is expandable to an expanded position opening the fluid passage. In use, upon introduction of a pressurized fluid at the inlet end fitting the flexible hose expands from the collapsed position to the expanded position to permit flow of the fluid through the fluid passage towards the outlet end fitting. Upon termination of the introduction of the pressurized fluid at the inlet end fitting the memory of the elastomer material collapses the flexible hose from the expanded position to the collapsed position expelling the fluid from the fluid passage.
