Which Pressure Washer Hose Connector & Coupling Fitting to use?


Review By -

If you have bought or are buying a pressure washer then the only other thing you need to consider is the water supply to this, this could be via a outdoor tap, bucket of water using a function pipe, or connected to a water butt. If you have an outside tap then you may already have a hose pipe connected to this.

If you don’t then you will need to purchase one if you want to hook it up to your pressure washer, this gives you more flexibility allowing you to have the pressure washer on your front drive, if the outside tap is to the rear of your property.

Which Hose Pipe Connector to use?

Most pressure washers use the same style and design push and click connectors, this could either be a Karcher or Nilfisk connector, or a Hozelock connector, the way they work is the same.

However, due to them being made by different companies, they are all made to work with other connectors they produce, and what you will find is that there are very slight and marginal differences between them, in size and fit.

By mixing different branded connectors you may find slight leaks where they join, or poor water flow, or at worst the connectors just not holding and with the pressure washer on the connects blowing off.

Karcher Hose Pipe Connector

If you own a Karcher pressure washer be it a new or older model of the K2, K4, K5 or K7 power washer range, then the Kärcher Hose Connection Set For Pressure Washers is ideal.

Karcher Hose Pipe Connector

As it says it is designed specifically for use with pressure washers. The set comes with a 10m of Primo flex hose and all the connectors you need, you get a tap adapter that screws onto the outside tap, and then two universal hose connectors of which on come with aqua stop.

These are designed specifically for Karcher pressure washers making the joint and connection a perfect match.

Nilfisk Hose pipe connector

Unlike Karcher Nilfisk don’t offer a special hose pipe kit for their pressure washers, they are supply some plastic connections to get you started but these are not the best.

We would advise buying some metal connectors, these could be the Hozelock Pro Metal Hose End Connector or we recommend the Gardena Premium Metal Hose Connector which we talk about further below. Metal connectors will give a stronger and more robust connection unlike plastic connectors which can easily be blown off when using with a pressure washer.

Avoiding Water Stop Connectors

Auto shut off connectors can be bought and used, however when it comes to using with a pressure washer it can effect the flow of water meaning that you may not get the maximum flow of water output that your pressure washer can handle. This will be because the auto shut off effects the flow of water making it slowly before it reaches the pressure washer, so with this in mind we advise avoiding these types of hose pipe connectors.

Best Hose Pipe Connector

Sometimes it pays to pay a little more, and when it comes to using it with a pressure washer a solid, strong and robust connection is vital. Most standard hose pipe connectors from many popular brands are made from plastic, however paying a little more allows you to purchase a metal ring hose connector that is more robust and gives a better and longer lasting connection.

Gardena Premium Metal Hose Connector

This is a very high quality premium hose connector that uses the commonly found pull releases the connection, and push and click fixing.

Gardena Premium Metal Hose Connector

It comes with a grooved soft plastic grip, a protective rubber ring and stable clamping nut made from high quality metal giving a strong connection. The Gardena Premium Metal Hose connector is suitable for 12mm – 13mm diameter hoses and comes with a 2 year warranty.

It is well made and provides a great seal and joint. These maybe slightly more in price but they last longer and are more robust.

My hose keeps blowing off!

If you have your pressure washer all set up but find the hose pipe keeps blowing off when using it then the likely reason will be that you are using plastic connectors that are certainly not the best. We would advise buying some metal connectors like mentioned about such as the Gardena Premium Metal Hose Connector which will hold better and should prevent the pipe blowing off.
