High pressure hose couplings from Kärcher are universal and connect all standard hose pipe series, helping you achieve the best results for your garden.
In order to cover the various interfaces, from the highpressure cleaner to the nozzle, as well as forward and backward compatibility, a total of 8 different adaptors are available. This ensures that all existing machines and accessories can continue to be used together with the new machines and accessories with EASY!
As they are such versatile cleaning tools, pressure washers usually have interchangeable parts and accessories to better suit specific demands. The RS range of pressure washer parts has replacement parts and accessories for pressure washer models from leading brands.
No, not all pressure washer accessories are universal, nor are they always interchangeable. Accessories may differ in fittings from one machine to another and may not fit together correctly. Some pressure washers are also brand-specific, meaning they will only work with accessories from the same manufacturer.
Gas Pressure Washer Attachments

There are only three basic types of connections used on gas units: M22, 3/8″ threaded, and Quick Connects. The only exception is with the gun and lance.

Pressure washer hoses are not universal. They come in different diameters, lengths, and materials. So, choosing just any hose to replace your current hose won`t work. You`ll either end up with a hose that doesn`t match the performance you`ve come to expect, or you won`t be able to connect the hose to your unit at all.
Regardless of the hose diameter – 1/2″, 5/8″ or 3/4″: Kärcher`s ultra-watertight hose connectors are always the perfect fit – guaranteed. The universal hose connectors also boast outstanding resilience and maximum tensile strength. The connectors are available with or without aqua stop.
Are Replacement Guns Universal or Do I Need the Same Brand as My Pressure Washer? With the correct arsenal of threaded and quick connection fittings you can make any spray gun 100% universal. You definitely don`t need to buy a replacement or upgrade spray gun as the same brand as your pressure washer.
Pressure Washer`s are commonly connected to a running tap via a hose; however they can also draw water from sources such as a rain water tanks & garden bucket with the same performance. So this means you don`t have to miss out on using your Kärcher summer!
No, they come in a variety of designs and sizes for different tasks. For example, there are male and female connectors, terms that refer to the way they attach to other hoses or connectors.
Diameter. Small (1/4″) hoses are the most common. They are designed for consumer-grade electric and small gas power washers with pressure ratings up to 3,200 psi. Mid-sized (5/16”) hoses are the least common.
The outer diameter is 22 millimeters, with a metric 1.5 thread count, on the male end. However, the female end has an inside diameter of 20.5 millimeters, but still has the metric 1.5 thread pitch, and generally has an O-ring to prevent leaking. These threads are common on pumps, hoses, and spray guns.
This coupler is designed to help you extend the reach of your high-pressure hose. Simply use this coupler to link 2-hoses together and you`ve doubled the reach of your hose.
Ideal for cleaning all smooth surfaces such as paint, glass or plastic: The interchangeable Universal attachment for the WB 130 rotating wash brush.
No, they come in a variety of designs and sizes for different tasks. For example, there are male and female connectors, terms that refer to the way they attach to other hoses or connectors.
Universal interchange quick-connect air couplings are designed to work with other interchanges accepting multiple styles of nipples, including industrial, Tru-Flate, and ARO. The push-to-connect style has a protective sleeve that slides forward until the plug ejects.

Soap feed The soap feed hose on my Karcher 2650 does not suck up the soap into the washer. I pulled off the connector piece that the hose is connected to. I can blow through the hose. There is a little metal finger thing that you can tell pushes up into place when the water pressure is high. It seems like it is supposed to drop down and allow some soap through when the water is running. I found a loose(attached to nothing) gasket, looks like a little donut. It was just free floating in there. I’m thinking it may go over the finger mechanism. I just put it back on top of the finger, like a halo and put the screw in piece back in. Anyway, if you know, let me know how all that goes together.
ANSWER : I fixed mine works good too, watch my video step by step i put it on youtubehttp://www.youtube.com/watch?v=UFXSLOBL0Mg
