Kärcher Curved Handle DN50 – 9.977-678.0

The Kärcher Curved Handle DN50 (9.977-678.0) is a genuine professional industrial vacuum accessory designed to provide a durable, ergonomic connection between a DN 50 suction hose and compatible cleaning nozzles. Manufactured from stainless steel and formed with a 45° bend, the handle is built for demanding commercial and industrial vacuuming applications where strength, control and long-term reliability are essential. Kärcher also specifies the handle as electroconductive, making it particularly suitable for use as part of correctly configured industrial vacuum systems where static discharge control is important.

The 45° curved design gives the operator a more comfortable working angle when vacuuming floors, machinery, production areas and confined spaces. Rather than connecting a suction nozzle directly to a straight hose, the handle provides a rigid and controlled grip point, improving manoeuvrability and making it easier to position the nozzle precisely during detailed industrial cleaning work.

Its DN 50 inner cone is designed to integrate with Kärcher's larger industrial vacuum accessory systems, including compatible hoses, floor nozzles, surface nozzles and standard suction tools. The large nominal diameter supports the high airflow requirements of professional Kärcher industrial vacuum cleaners, making the handle suitable for intensive applications involving dust, liquids and industrial residues when used with the appropriate machine and accessories.

The electroconductive construction is especially valuable in industrial environments. As material moves through a vacuum system, static electricity can accumulate in non-conductive components. When incorporated into a suitable conductive accessory chain, the handle helps maintain electrical continuity and supports the dissipation of static charge. This makes it an important component for many professional vacuum configurations used in workshops, manufacturing areas and other demanding environments.

Kärcher uses this handle as part of its Liquid/Solid Accessory Kit Expert DN50, where it is paired with the 3 m PU hose 9.989-619.0, standard nozzle 9.988-402.0 and 120 mm surface nozzle 9.988-119.0. This demonstrates its role as a central connection component within Kärcher's professional DN 50 industrial cleaning system.

Built from coated steel/stainless-steel construction and weighing approximately 0.5 kg including packaging, the handle combines strength with manageable weight for repeated daily use. As a genuine Kärcher OEM accessory, it ensures correct fitment with compatible Kärcher equipment and helps maintain the intended airflow and mechanical compatibility of the complete suction system.
