## Long description

Suction hose Karcher NT DN40 4m is a replacement or spare hose designed for Karcher NT series wet/dry vacuum cleaners. The hose features a DN40 inner diameter and a 4-meter length, providing extended reach for extraction of debris and liquids. Manufactured to fit compatible Karcher NT fittings (MPN 2.889-138.0, EAN 4054278256313), the hose helps restore or extend the working range of NT vacuums and supports cleaning tasks in workshops, garages, vehicles and construction sites.
Advantages
The DN40 diameter balances airflow and maneuverability to maintain suction performance while remaining flexible enough for confined spaces. A 4 m length increases operational reach without requiring frequent repositioning of the vacuum unit. The hose is produced to match Karcher NT connection standards, ensuring secure fitment and reliable sealing when attached to original NT accessories. Its construction resists typical wear from dirt and liquid transport and is suitable for wet and dry extraction applications.
Suitable for
Replacement or spare part for Karcher NT series wet/dry vacuums

How to use
Attach one end of the suction hose to the Karcher NT vacuum inlet and the other end to the appropriate accessory or nozzle. Ensure connections are fully seated and locked according to the vacuum cleaner’s accessory interface. For liquid extraction use, verify that any required float or filter components on the vacuum unit are fitted and operational. Route the hose to the work area, avoiding sharp bends or kinks that could restrict airflow. After use, drain residual liquids if applicable, clean the hose interior and exterior, and store the hose coiled in a dry place to prolong service life.
Usage recommendations
Use the suction hose with matching DN40 accessories to maintain proper airflow and suction efficiency. Do not expose the hose to temperatures beyond the vacuum manufacturer’s specified range or to aggressive chemicals not recommended for Karcher accessories. Inspect the hose periodically for blockages, abrasions or cracks and replace the hose if damage compromises sealing or structural integrity.
