Replacing a damaged Pressure Wash Hose Assembly

At Hoses Direct, we offer all types of hose assemblies, which includes jet wash / pressure wash hose assemblies, both for domestic and industrial use,  hot and cold water. We use Italian Hose and Fittings, these are not a Chinese Import Item.

Prices start at around £30.00 depending on the length and fittings required. If you have a low end domestic unit, it is sometimes more economical to replace the machine. If you are interest in replacing your hose then a range of the the shelf items can be seen here

We also do bespoke hose assemblies with lengths up to 100mtrs, hot and cold wash, steam wash hoses, non marking wash down hoses, and all other high pressure cleaning hose assemblies, so please get in touch with your requirements,

Hose Type

First thing to do is check what type of hose you have, these are usually one wire or two wire hoses, and it should be marked on the side of the hose with the pressure rating. Typically available in blue or black

End Fittings

There are a couple of common end connections for pressure wash hose:

The Metric 22mm “Karcher” end – easily distinguishable with the black plastic round swivel nut on the outside, and the stem with O Ring on the inside. The should measure 20.5mm inside diameter across the threads


Karcher M22 Female

Then there’s the 3/8″ BSP End Connection, available in bot male and female threads. The male will be coned inwards, and the female coned outwards. With the male measuring 16.5mm outside diameter (O.D) across the threads, and the female measuring 15.2mm inside diameter (I.D) across the threads












Then there’s the not so common ends. From to to bottom, There is the Kew Type Male, then Kew Type Female, 10mm Karcher Type (with washer no bearing) , 11mm Karcher Type (bearing/washer), 10mm Karcher Type Fixed Washer , and finally the Karcher Type Cup Fitting .

End Cuffs

After choosing the correct end fittings, and the hose, you can then have it with out without end cuffs.  Again, available in blue or black, and help when gripping the hose

Nozzles & Lances

If you require a nozzle or lance, these can also be bought from Hoses Direct

How To Measure and Identify Hydraulic Threads

This is something I often get asked; ” How do I know what thread it is?

Our aim is to deliver you with all the help you need to successfully measure and identify hydraulic fittings threads, by using this thread guide.  Hopefully by the end of reading this post you will be a little more informed, and find the process less daunting.

First off, we have a PDF guide on the website, which covers the size range, and I will reference to this in the post as it has all the technical data in there.

If you want to download, save and print a copy of the thread guide, then please visit the link here.

Things will you need:

  • Thread/Pitch Tool – (Ideally)
  • Vernier Calipers - Preferably digital and calibrated for a more accurate reading (Essential)
  • A variety of fittings for testing this out on

The first thing to do is establish is the thread gender,  do we have a “male” or “female” thread? The easiest way to see this is, Is the thread on the outside (male) or on the inside (female)

Below is a bush – this shows both the male and female thread. With the male on the outside

After we have looked at the fitting, and identified the gender, we can then measure it using the vernier callipers.  As you can see from this fitting, it is a male thread, and I have got a measurement of 20.81mm . In some cases this may be enough to identify the fitting, but to be certain we would also confirm the seat angle, and the Threads Per Inch (TPI)

Looking at my hydraulic thread guide PDF, on page 3, under the BSP threads, and the male thread OD mm column, I can see a size 1/2″ has a male thread OD of 20.8mm. The 1/2″ ORFS on Page 5 comes close at 20.6mm, all the other threads are too far out.

So we move on to the TPI, where the BSP has  14 TPI and the ORFS has 16 TPI. This is where we would use a thread pitch tool. Using my pitch guide I can see this is 14 TPI

If you do not have this tool, there is another way. But I must state this is a rough guide, and do not want to be held responsible. Using the vernier we can count the threads across a 1″ measurement, or 1/2″ measurement, then double that number. This isn’t the most accurate way, but it will do if you do not have all the tools.

But the main difference in the BSP threads and the ORFS, is the seating. The BSP usually has  a 60° cone seating, whereas the ORFS has a O Ring in the face of the male thread.

Some tools will have a seating angle measurement as well. Using the tool I can see this is a 60° cone seating, which confirm to me this is definitely a 1/2″ ( -8 ) BSP Thread.

If you are not confident measure threads, we can of course guide you through it , or you send in your fittings and we will identify them. We can make hoses to your specification without you having to call out an on=site hydraulic hose repair company.

Hoses Direct Supply Caddy Macrofix Clips from the UK to the USA

Supply of : Over 3000 Caddy Clips to a US Pipe Fitting Supply Company

So how did it start ?

It started off with an email back in October 2012, a Pipe Fittings Company with a  request for a large amount of Caddy Stainless Steel Macrofix Rubber Lined Pipe Clips, and Unlined Macrofix Clips, in various sizes, to be shipped out to the USA. First things first, I checked out the company on Google , and they looked to be a reputable seller, so we went through the motions of providing a quotation, looking into shipping costs and lead times. We have all seen the inbox filled with enquiries from overseas looking to buy large volumes of a product they have seen online,  is it just more junk , or could this be genuine.



After a week I received a purchase order, I thought this is too good to be true. Then after opening it I could see it was for the clips I had quoted for, but for a quantity of 1 each. The 3000 clips, turned to 16.  Before I got too disappointed I read the covering email, which stated these were a sample for approval, if they are accepted we would receive the full order. Sure…we have all heard that, get the best prices for large quantities then just order one. But, giving benefit of the doubt, we agreed and arranged an express mail back out to the States.

A few follow up emails later, We did indeed receive the full order. Excellent ! After a quick stock check it was clear we need to get on the good side of the manufacturer in order to get these out as soon s possible. With a great help from all parties involved, including 4 different shipping companies I can happily say the clips are sea bound and will be with the customer in just over a week from now.
