Product Information
Full details
The Kärcher 10-metre high-pressure extension hose is designed for Kärcher domestic pressure washer users (1-4 series, excluding new X range and quick-release models) who need to extend their cleaning radius. Its key benefit is providing an extra 10 metres of hose length, allowing for greater reach and flexibility. A caveat is its incompatibility with certain newer Kärcher models. This accessory enhances productivity by enabling users to clean larger areas or hard-to-reach spots without frequently repositioning the pressure washer unit. Key features include a robust, non-kinking design with textile braiding for durability and a brass connection for secure, long-lasting use.

FAQs
Will this extension hose fit my Kärcher K5 pressure washer?
This 10m extension hose is designed for Kärcher 1-4 series pressure washers with screw-thread fittings (typically pre-2007). It is not compatible with the new X range or machines with quick-release fittings, which may include some K5 models. Please check your machine's connection type.
Can I use two of these extension hoses together?
While technically possible, connecting multiple extension hoses may affect pressure and flow rate. It is generally recommended to use only one extension hose for optimal performance.
Is this hose suitable for hot water pressure washers?
This accessory is designed for cold water domestic pressure washers. Using it with hot water may damage the hose material and void its warranty.
What is the diameter of the hose (DN rating)?
The hose has a DN 8 rating, indicating a standard diameter suitable for high-pressure applications within its compatible range.
How do I clean the extension hose?
Wipe the exterior with a damp cloth. Ensure it is completely dry before storing. Avoid using harsh chemicals or abrasive cleaners.
What is the maximum pressure this hose can handle?
The product information specifies it's a high-pressure extension hose. While a specific PSI rating isn't listed, it is designed to work with Kärcher domestic pressure washers and should not exceed the limits of the machine it's connected to.
Troubleshooting
Low pressure or water spray inconsistency.
Check that all connections (extension hose to original hose/gun, and gun to lance) are securely tightened. Ensure the extension hose is not kinked.
Leaking at the connection point.
Verify the brass connector is fully screwed in and that the seal/washer (if applicable) is present and in good condition. Inspect the threads for damage.
Hose is difficult to connect.
Ensure you are using a compatible Kärcher pressure washer model. Check the threads on both the hose and the connection point for dirt or damage.
Hose appears damaged or worn.
Discontinue use immediately. Inspect the hose for cracks, cuts, or bulges. Replace if any significant damage is found to ensure safety and performance.
