To be able to use a pressure washer effectively, it is important to find the right hose. Whether it is to replace the original appliance hose or to extend it with another hose – some specifications should definitely be taken into account.
The most important thing is the connection of the pressure washer hose. Most manufacturers use M22x1.5 or M14x1.5 threads.
In addition, the pressure and temperature resistance of the hose should match the performance values of the pressure washer and ideally even be slightly higher.
Last but not least, safe use of the pressure washer hose can only be guaranteed if it is checked for damage before use.

Suitable pressure washer hose for Kärcher pressure washers
Kärcher pressure washers are equipped with a so-called Quick Connect System. This allows the pressure washer hose to be attached to the cleaning device with a simple plug-in. This eliminates the need for lengthy screwing or annoying squeezing.
To detach the hose again, only the button has to be pressed. For the system to work, the hose must also have such a Kärcher Quick Connect connection. The brand hoses available from Kärcher dealers have this Quick Connect connection as standard.
If you already have a pressure washer hose with an M22x1.5 thread, it must be equipped with a Kärcher adapter. The same applies to hose extensions with such a thread: here, too, the Kärcher adapter must be connected in order to connect the hose and the pressure washer. By the way, the Quick Connect connection has the so-called NW 6×1 connection.
The old connection was known as the slide lock / connection clamp. However, you can make everything compatible with separately available adapters. PS: The adapter is sold under the name: Kärcher T Adapter.
The properties of a pressure washer hose explained:
The connections / threads of a high-pressure hose
In principle, a distinction must first be made between external and internal threads. Only male and female threads can be screwed together; two male or two female threads cannot be screwed together.
If you want to connect two pressure washer hoses, each with two male threads, you face the problem that they are not compatible with each other. A so-called hose coupling makes it possible to screw the hoses together.
The various designations for the threads also tend to cause confusion. For example, the term for an M22x1.5 thread. This designation characterises the thread and gives its properties in short form.
The first number refers to the width of the thread. The capital letter “M” at the beginning of the designation means that this is a metric thread and thus specifies the density of the turns, etc. The second number, in this case 1.5, refers to the width of the thread. The second number, in this case 1.5, refers to the height or depth of the thread.
The threads of the Kärcher and Bosch pressure washers differ from this system. These rely on Quick Connect or quick connection systems, which can only be made compatible with the conventional threads of the system described by using an adapter.
The term DN / nominal diameter
The term DN comes from the French Diamètre Nominal and indicates the nominal width and thus the inner diameter of a pipe or hose. It is used to select suitable connections and fittings for the corresponding hose.
Care must be taken to ensure that all components used have the same DN. If, for example, you want to connect two hoses for a high-pressure cleaner as an extension, not only must the threads be suitable, but the nominal diameters must also match.
One of the reasons why a electric pressure washer achieves such good results is that it applies water at high pressure to the surface to be cleaned. Therefore, all components used in the system must have a certain pressure resistance.
Pressure washer hoses have different pressure strengths. Some models are designed for use up to 200 bar, while others can also be used at 400 bar. When buying a pressure washer, it is therefore important to know exactly how much pressure it can withstand. The pressure resistance of the pressure washer hose should ideally be a little above this value.
The temperature resistance
When using a “normal” pressure washer, the temperature resistance of the hose is not of interest.
However, if a hot water pressure washer is used, the temperature resistance must be taken into account, because these devices work with water temperatures of up to 155 degrees Celsius.
Not all materials can withstand these temperatures. The temperature resistance of a pressure washer hose provides information about the temperature up to which the water can be safely conducted through the hose.
What is a kink protector for?
The kink protector is typically located at the beginning and end of the pressure washer hose. It prevents the hose from kinking or breaking at the connection to the pressure washer if the hose is pulled too hard and damage occurs. It thus protects both the equipment and the user.
Does it always have to be an original hose?
When choosing the right pressure washer hose, it does not always have to be a branded product, as long as the specifications described in this article are observed. Special attention should be paid to the compatibility of the connections.
The “operation” of a pressure washer hose
Since considerable forces are involved when using a pressure washer, the equipment used should be checked before each use. The pressure washer hose should therefore be completely unrolled and checked for holes.
Even small holes can pose a great danger. You should also make sure that there are no knots in the hose, otherwise they can burst when the pressure washer is switched on, posing a considerable risk of injury.
