Used as a replacement, the hose is longer than most hoses included with pressure washers and is made of durable rubber, greatly extending the life and performance of the hose. Includes four metal connectors to ensure compatibility with Kärcher and other brands of pressure washers. Some assembly required. The hose is non-marking, with an interior diameter of 5/16 inches (8mm) and an exterior diameter of 43/64 inches (17mm) max. NOTE: Not compatible with Kärcher K2-K5 electric pressure washers
