Abstract
A flexible pressure-washer hose and pressure washing apparatus are disclosed. The hose is of concentric laminar construction and comprises an inner core, an intermediate sheath covering the core, and a jacket covering the intermediate sheath. The disclosed hose has a burst pressure of at least 8000 psi, yet is highly flexible, such that the hose has a minimum bend radius of no more than about 38 mm. The disclosed pressure washer comprises a hose made in accordance with the invention and fluidically connecting a source of pressurized fluid to an operator wand.
