Karcher 9.988-402.0 Nozzle Elastic Silicon DN52

The Kärcher Standard Nozzle Silicone DN50 (9.988-402.0) is a genuine professional suction nozzle designed for Kärcher's DN 50 industrial vacuum systems. Manufactured from flexible silicone, this specialist nozzle provides a combination of durability, elasticity and adaptability, making it particularly useful for targeted vacuuming around machinery, equipment and difficult-to-access areas where a rigid nozzle may be less practical. Kärcher specifies the accessory with an ID 50 nominal connection width and a packaged weight of approximately 0.3 kg.

Unlike conventional rigid PVC or aluminium vacuum nozzles, the silicone construction gives this accessory a degree of flexibility that allows it to adapt more readily to the working area. This can be particularly useful in industrial environments where operators need to vacuum around machine components, edges, corners and irregular surfaces. Kärcher's documentation for the corresponding DN 40 version describes the design as a stretchy silicone standard nozzle, with the DN 50 version forming part of the same industrial nozzle range.

The nozzle's DN 50 connection is designed to integrate with Kärcher's larger industrial vacuum accessory systems. The relatively large internal diameter supports the high airflow requirements associated with professional industrial vacuum cleaners, making the nozzle suitable for demanding cleaning and maintenance work when paired with an appropriate machine and hose system. Kärcher officially lists it across numerous IVC, IVM, IVR, IVR-L and IVS industrial vacuum models.

Its compact nozzle format makes it particularly useful for concentrated suction work rather than cleaning broad floor areas. Operators can direct suction precisely towards contamination around machinery, production equipment and other confined working areas. The flexible silicone body can also make positioning easier where access is restricted or where a more forgiving nozzle material is desirable.

This makes the 9.988-402.0 a useful addition to industrial vacuum setups used in manufacturing plants, engineering workshops, maintenance departments, production facilities and industrial cleaning operations. It can complement wider floor and surface nozzles by providing a more manoeuvrable option for detailed cleaning and localised contamination recovery.

As a genuine Kärcher accessory, the Standard Nozzle Silicone DN50 is designed to fit approved Kärcher DN 50 systems correctly and maintain the intended airflow through the vacuum accessory chain. For facilities already operating Kärcher industrial vacuums, it provides a simple but highly practical way of increasing the versatility of the machine without changing the complete suction setup.
