The versatile Karcher 25 ft. Replacement/Extension Hose serves as both a replacement and extension for all Karcher gas (and select electric) pressure washers. As an extension, the replacement hose expands the working range of a pressure washer by 25 feet, enabling you to clean a larger area without moving the pressure washer. As a replacement, this replacement hose is longer than most included with pressure washers and is made of durable plastic, greatly extending the life and performance of the replacement hose. This thermoplastic replacement hose fits Karcher gas models rated up to 3600 PSI, Karcher electric models K1700-K2000, and most other brands of power washers (up to 3600 PSI) that have either standard Quick Connect or M22 hose connections.
