For those of you who own, or are planning on owning an AR Blue Clean AR390 pressure washer, you might have run into the same dilema I did. There is no way to clearly tell what fitting to use when adapting the Autogeek Foam Cannon.

I searched the internet high and low, prior to purchasing the unit, for connection dimensions, or user photos to determine what fitting would fit the AR390's wand. By the way, the AR390 uses different connections than the AR383, or any of the other AR Blue Clean pressure washers.

Anyways, below are pictures of the AR390's wand, the connection type and the KRANZLE fitting that fits on the end of the wand.

Hope this helps :)
 
How is the washer working for you? What fitting is that because this is the one thing I have been waiting on to purchase this pressure washer.
 
Oh it works great! The fitting is the KRANZLE fitting (same fitting that Autogeek uses for the demonstration with the Honda Pressure Washer Wand).

The AR390 uses a different connection than the more popular AR383, which uses a connection similar to a Bosch and Karcher K fitting.

The AR 390 has a brass thread connection for it's wands and the foam cannon, versus the quick connect (twist and lock) connections on the Karcher and other brands. I like that threaded connection feel better IMO.

Hope this helps :xyxthumbs:
 
Awesome thanks my 390 came today and my MTM foam lance will be here monday. I got that one because it comes with a Kranzle fitting attached.
 
That's great! How is working for you? Do you like the 390?
 
It works awesome. The AR390 is well worth the extra money over the 383. The hose is less prone to kinking. It uses a standard M22/Kranzle fitting for connection. Which thanks to you I knew ahead of time! Great products!
 
Can you please provide links to the exact fitting you purchased? I recently received an MTM Hydro foamer and have been trying to find a pressure washer with the least amount of 'extras' required to get it to work with an inexpensive pressure washer. If you've gotten the AR390 to work with the MTM by only purchasing one additional adapter that's great!

And to confirm, no extra 'fiddling' with parts, connectors, etc.. was required?

Thanks!
 
You going to like what im about to say. You have to purchase nothing else. The AR390 uses M22/kranzel brass fitting which the MTM comes with. No additional fittings needed just buy and apply. The AR 383 needs a whole mess of mod work.
 
Hey Newb001, here is the link to the fitting on Autogeek's page.

Kranzle Pressure Washer Fitting

To further back up buildbright's words, the AR390 is definetly worth the money! The Water flow rate and the flowing pressure (1.6gpm/1800 psi) are a great pair for cars. It's a very solid unit, definetly recommend. It's also nice to have all brass connectors versus plastic IMO.
 
Thanks for the info! Sorry, just to confirm, do I need the Kranzle fitting for the AR390 or AR383? I'm definitely getting the AR390 (might actually get it on ebay, manufacturer refurbished, for $125)

You need the Kranzle for the AR390. See the pictures at the top of the thread.

The 383 uses a connection similar to the Karcher K series and the Bosch series of pressure washers.

Hope this helps.
 
Just got my AR390 today and I've got a couple of questions:

1. Please see 1st pic below (after the AR390 stock photo) and let me know if that's how I should be connecting the MTM. I didn't have a wrench handy so I couldn't remove the silver color quick adapter, but I think I need to remove it and instead screw in the gold color adapter that came with the cannon, and then the other end of gold adapter should fit in trigger gun, which of course I forgot to try before I came inside...

2. As for the AR390 itself, I can't figure out how to connect the garden hose (end of garden hose is male as is water outlet on AR390). Either I'm an idiot (quite possible) or something is wrong/missing. Only thing I could do was use the blue and black quick connect that came with AR390 and connect it to the hose, then I connected the clear colored adapter to the AR390, then the blue/black connected to the clear adapter. However, no water gets from hose to AR390. It's stopping at the blue/black connector.

[UPDATE: I just googled the AR390 and I see that it's supposed to have a black piece over the hose adapter, whereas mine is just a silver colored female end. Maybe it fell off in box. I'll have to check in the morning unless anyone has any other suggestions.

Here's how I'm thinking the cannon connects to AR390:

Here's how I connected the hose:

Here's everything I have (5 AR390 parts and 2 MTM parts, canister not in picture):

In my post I said it was a silver colored female end, I of course meant it's a male end, and therefore I can't connect the male hose to the male connector on the AR.

1. Well by the looks of the photos, you have everything you need. Make sure that "gold fitting" that came with MTM fits into the Trigger gun, as in it threads to the trigger gun. If that works, then get a wrench and remove that male quick connect (silver fitting) from the MTM, replace it with the gold male adapter (make sure to put Teflon tape on the threads!) and you should be good to go as far as the MTM is concerned.

2. According to the photos, you have the garden hose adapter hooked up right (female end hooked to the hose, quick connect end hooked to the male connector on the pressure washer (silver connector).

From what I can see in all of your photos (which showed everything very well) you are doing everything the correct way. Let me know if you need anymore help with, I can send some current photos of my AR390 if you need.

*Remember to put teflon tap on the threads for the male connector going into the MTM, not the threads going into the trigger gun.
 
Thanks so much for the follow-up. The gold connector does fit into the trigger gun, now it's just a matter of finding my tools (we just moved and I still haven't found where we packed the tool box...). Looks like it should fit though and I'll go get some new teflon tape.

As for the hose to AR, does your AR have the black connector at the end like in the stock photo? Or you just have the silver thread and connected as you said (hose --> 2 connectors --> AR)?

The problem I have is if I just connect the blue/black connector to the hose, and turn on the water, nothing comes out. The hose isn't kinked and the water is flowing properly, it just stops at the blue/black piece.

Also, the blue/black connector into the clear connector doesn't seem the sturdiest and I feel like it could easily snap off if I'm moving things around.

With my parent's old (and cheap) PW, the hose just connected directly to the PW. Any reason why this one requires 2 adapters?

Thanks again!

If you wouldn't mind sending a photo of your hose connection that would be great. Can you also confirm if the blue/black garden hose adapter allows water to pass through it without being connected to the AR? In other words, if you connect the blue/black connector to the hose (without any other connections to the AR), and turn on the water to the hose, does water come out? In my case, it does not. The blue/black connector is 'blocking' all water flow. I tried it again today and can't figure out what I'm doing wrong.

Thanks again!

They are not adapters per se. The clear piece has a filter in it.
I just got my 390 and I connected everything the same way you did. I won't be testing for another week or so, but curious if you ever got it to work.
Reading amazon reviews that is how it's supposed to be connected. Quick connect attaches to the hose and the filter piece attaches to the pressure washer.
 
Yeah, just be sure to really push the clear piece into the quick connect. I didn't have it all the way in apparently. In fact, it took a contractor who was at my house (a much larger gentleman than myself) to force the two pieces together. Now that I know that's how it goes, I'm able to do it myself, but it really takes all my might.

As you can see here:

I had it connected, but apparently not all the way. It was definitely clicked/locked into place, but had a lot of movement. Once the contractor pushed it all the way in, there was no more gap and no more movement. Then it worked fine.
