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 metallic sheath covering the core, and a jacket covering the intermediate sheath. The disclosed hose has a burst pressure of at least 12,000 psi, yet is highly flexible. 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.
