Pressure Washer - busted threads fix?

[Aquamoose]

Guys,

I've got a good pressure washer that has busted threads on the bottom of the machine that connects to the spray hose. I'm disappointed that it's made of soft cast aluminum. I've always been careful not to cross thread my connectors on my stuff. I installed it fine but when taking it off, it simply just lodged itself and I had to take a pair of pliers to really unscrew it and now I have bad threads. Anyone have the same experience and how do you fix it?

Pics would probably help.

Try running a tap in there?

Make your own time-sert, just need a tap the size of your hose end, a die in whichever size you like and a piece of rod, I'd probably do pipe thread. My other suggestion being that the hose is usually brass in an aluminum, the dis-similar metals like to corrode to each other, is to put liquid pipe tape or anti sieze on it.

I would buy a quick connect kit and install it (female) on the pump housing and never take it off. connect the other (male) to the hose

And or go to the standard, and M22 -3/8 converter

Where can I find the quick coupler kit? I could carefully repair the threads on the pump before installing one and I’d have to replace the hose because the threads are messed up on one end.

Can you elaborate please?

If you can find a thread file with the same pitch, I would try that. They have saved me much grief in the past.

On mine, I put a pair of channel locks on the plastic part where you screw the hose on by hand. Once that broke off, there was a brass hex head onto which I put an appropriate sized wrench and moved it fractions of an inch back and forth (using penetrating oil) until the corrosion finally gave up and came off. For me the threads weren't boogered up; it was the aluminium corrosion. I'd hit yours with a wire brush and maybe a file. Could also be the threads on the hose that are a problem.


My garden hose had some of its threads goofed up from being drug on concrete. I took a small file and went over the compressed threads and it it now screws on fine to the pressure washer.

Oh how i love aluminum on aluminum threads

Is that aluminum on aluminum or is the hose fitting brass with a bunch of aluminum corroded onto it?

 

[The Cobbler]

usually the pressure washer connectors are steel I think , so it's steel on aluminum

I would use these type of quick connects. just confirm the sizes .

So those two combined makes it a quick disconnect at one end?

yes, but just be sure on the thread sizes etc . most of them are 22mm I think but you need to be sure yours are
