Machine connectors and adaptors for HD & HDS professional pressure washer systems
This category covers HD & HDS Machine Connectors & Adaptors designed to convert between the two main machine connection thread standards used on professional Kärcher pressure washer equipment, allowing safe and correct integration of hoses, hose reels, and accessories across mixed or evolving systems. These machine-side connectors and adaptors are fitted at the pressure washer outlet and are used to adapt between EASY!Lock trapezoidal threads and legacy metric threads, helping professional users maintain compatibility when operating equipment from different generations. Suitable for use with cold and hot water pressure washers, this range supports secure connections that maintain consistent water flow and operating pressure in demanding commercial and industrial cleaning environments. By enabling correct adaptation between EASY!Lock and legacy metric thread patterns, HD & HDS machine connectors and adaptors help prevent leaks, pressure loss, vibration-related loosening, and component damage that can occur when incompatible fittings are forced together or incorrectly installed. Common applications include upgrading older machines, integrating existing hoses into newer systems, replacing damaged couplings, and standardising fleets where multiple connection types are present. Selecting the correct adaptor ensures proper fitment at the machine outlet, protects internal machine components, and supports safe operation and long-term reliability in professional cleaning operations.
