Hi guys, I have been wrestling this this thing for way too long now and thought I might ask the brain trust here…..
This is the hose end of an electric power washer. It was a very poor design. This is the fitting that fits into a quick connect fitting on the gun the came with the unit. Everything works fine on it except this fitting leaks terribly. I bought a new gun that has the m22 fitting on it and then bought a fitting that is M22 female to quick connect. It still leaks. I got fed up and bought another unit, but I would like to fix this one and give to a very nice family next door. the hose is some sort of hard plastic and is 7/16 OD.

Is there a fitting that is a hose repair type deal that will end in either a quick connect male end or a m22? I have looked at putting on a new hose but not sure how to connect that end either?

I know we have every conceivable expert on any subject and I have never been shut out yet…..I have always gotten great ideas…..

Is it missing a rubber gasket?

Is there a manual and parts list for your pw?

i agree that looks crappy.ive never seen a quick connect fitting like that before,the gas unit ive got is screwed on firmly to to washer and the gun.id say maybe you could just replace the hose and gun with something better quality mike,i mean it will make a nice gift fixed but may make a sour neighbor if it leaks all the time,you dont want that.

Thanks guys….
No I don’t think it is missing anything, I did file on the brass to make it fit into the standard quick connect…..it didn’t even have a standard quick connect. It’s something that is proprietary. It’s a quick connect built into the gun and it is buried inside it….I tore it out and it close to a normal quick connect but not quite….I suppose that I am going to have to get a new hose but with thing being as weird as it is, I am afraid it will have some weird connector there too, and I can see some sort of strange retaining ring/wire. There certainly isn’t a M22 outlet down in there like there should be! Plus I’m into this give away 60.00 now….I just thought there might be a easier way I didn’t know about…there is a lot of hardware out there…

This fitting appears to be pressed together. I’ve tracked down the leak and it appears to be coming from up in that aluminum part. I originally thought it was the fitting in the gun, but no. I thought about epoxy up in there or some kind of sealant, but it’s a power washer, wouldn’t it spit it out?

Pottzy, I got pi$$ed off about 3 years ago when one Sunday afternoon I could not get my gas power washer, or gas blower to start, and my lawn mower started leaking gas from the carb. I now have a 40 volt push mower, blower, chainsaw, 2 different hedge trimmers, pole saw, and weed whacker and an electric 2000 psi power washer…....I sold everything that has gas except for my tractor and snow blower…...not that you would know what a snow blower looks like…...lol….ok I’m jealous….
It was expensive, but I push or pull a button and away it goes…..It’s awesome!

ive always been lucky with gas powered stuff i guess,i try and stick solely with honda powered equipment,never have any issues with theirs.but with the new battery technology i may agree thats the way for the future buddy.

That looks like a typical hydraulic hose crimp fitting. The brass portion has a barbed end which slides into the hose and the aluminum ferrule is crimped, forming a high pressure connection.
If it is leaking between the brass and aluminum, you are SOL as far as sealing it due to the strain and pressures involved.

Only solution I can think of (if you can’t find a factory replacement part) is to somehow convert the connection to standard pipe thread and just leave the hose and gun screwed together.

Hey Splintergroup…...you gave me an idea
https://www.amazon.com/gp/product/B004QAM166/ref=ox_sc_act_image_1?smid=ATVPDKIKX0DER&psc=1
hose clamp it and put a standard 1/4 quick connect end on it?

Hose clamps will never hold the amount of pressure you are dealing with. I would not recommend that you try hose clamps to hold any kind of pressure washer hose. That fitting is worn out. The silver sleeve part where the hose meets the fitting is swaged on with a high pressure hose machine. If there is some one in your area that has the capability to make new hydraulic hoses, like for backhoes and such they might be able to make you up a new hose if they have or can get the fitting. Otherwise, I think if it was mine I would go to a Lowe’s or tractor Supply and replace the entire hose, fittings and gun with typical standard type fittings.

sounds like your generosity is going to get expensive and take up a lot of your wood working time mike.maybe a gift card instead.

Msinc is correct, a hose clamp will not hold the pressure (1000+ psi). You can get hoses made with most any fitting that can handle the pressure (auto part stores like NAPA do this), but they usually run about $50 or so for what you will need.

If you can wait a week or so for shipping (and actually want to spend money on this to give it away), northern tool sells a lot of pressure washer parts for relatively cheap.

Thanks guys, so much for that idea! I am to the point where I could have got him a new one soon! But I will not be defeated! We do have a “hose” place that fits new ends on things…I forgot about it….I actually had them repair my air hoses…..it took ten minutes and was very cheap….I’ll make that my next stop.
Thanks guys!
