What this adapter does Extends the length of compatible wash tools so you can reach higher or further without changing your cleaning setup. Lets you wash vehicles and surfaces without relying on a fixed water source, enabling use with portable pumps or mobile cleaning systems. Key benefits — why you need it Greater reach: clean roofs, windshields, wheel wells, and hard-to-reach trim from the ground, reducing the need for ladders or repositioning. Portable cleaning: works with mobile water supplies so you can wash cars, RVs, or boats where no garden hose is available. Durable and reliable: built from high-quality plastic and brass components to resist wear and provide consistent performance over time. Materials and performance Body constructed from high-grade plastic for light weight and impact resistance. Brass fittings for secure connections and improved corrosion resistance under repeated use. Designed for practical, everyday use with attention to durability and fit. Compatibility Specifically compatible with cleaning tools and accessories for models: WG629E, WG630, WG644, and WU629. Intended as an extension/adapter for those exact models — do not substitute for unrelated tool systems. Typical use scenarios Mobile car detailing: attach to your WG629E/WG630 series cleaning head and connect to a portable pump to wash cars in parking lots or at events. RV and boat maintenance: extend reach to rinse roofs, awnings, and hulls where a fixed hose is not available. Home exterior cleaning: reach high windows or gutters from the ground using a compatible tool head and a mobile water source. Practical notes Use only with the listed models (WG629E, WG630, WG644, WU629) to ensure a proper fit and safe operation. The adapter is designed for durability and ease of use; verify connection tightness before pressurizing the system. This adapter provides a simple, durable way to extend your existing WG629E, WG630, WG644, and WU629 cleaning tools and enables portable, ladder-free washing where fixed water sources are not available.
