Abstract
An expandable hose assembly that is able to expand one or more of longitudinally along the length-wise axis of the hose between hose ends and radially, to an expanded state in response to application of at least a minimum fluid pressure to an inner tube of the hose. Once the fluid pressure falls below the minimum fluid pressure, the hose will contract. The hose includes a thermoplastic elastomer inner layer and a slip coating layer thereon having lubricating properties that increases the life of the hose assembly. The hose assembly can include an outer sheath or covering that covers the inner tube and slip coating layer.
