M MINGLEPressure Washer Gun Adapter, to 1/4'' Quick Connect Fitting, Only Compatible Karcher K2, K3, K4, K5, K6, K7

Works great with my pressure sprayer

Perfect fitment for Karcher pressure washer. No leaks, the attachments are precise and powerful which makes it very effortless for its cleaning power.

I have an old Karcher 330 that has the pressure gun connected to one end of the hose so the gun cant be "swapped out" unless I buy a new hose for it. I instead purchased this little adapter so I can use the Quick-Connect stuff. it works okay. When the power washer is not shooting water, there are no leaks but when I squeeze the gun handle to use the washer, there is a small drip - not enough to really matter but since there is a small drip I wanted to mention it. gave it 5 stars because for $10 it allows me to use attachments like the round Surface Cleaner without needing to spend the money on a new hose and new gun.

At first The adapter appeared slightly too long to compress the spring enough to fit into the spray gun and did not fit and I assumed it would not fit but after reading several reviews that stressed upon the higher than usual pressure required to push the connector in I applied greater force and sure enough it locked in and worked great.

Reasonable price. Fast shipment. Very good quality product. Thank you.

Worked great.

Update: 2019-09-24 (5 stars)It turns out I got a bum unit that was leaking because oddly, the rubber O-ring inside the unit was missing! The seller kindly sent me a replacement adapter, and now everything works as advertised. Thank you for great customer service, and delivering a working product.Original review (1 star):Bought this adapter for use with "Karcher K5 120V Electric Power Pressure Washer X-Series" (https://www.amazon.com/dp/B01BMETE40) and "MTM Hydro PF22 Professional Foam Lance With Adjustable Air Intake and Fan Blades" (https://www.amazon.com/MTM-Hydro-Professional-Adjustable-Intake/dp/B01G4GPR5Q)This adapter fits the Karcher wand perfectly.The quick connect seems to fit fine (first picture) to the fitting that came with the foam cannon, thought it had some "wiggle" to it after connecting.After connecting everything between the pressure washer and the foam cannon, when actually spraying water, the water itself could come out of the quick connect seam (red arrows in the second image). Virtually no actual water got to the foam cannon so it didn't dispense anything. This made me believe that the quick connect isn't making a water proof seam so that the pressurized water simply comes out before getting to the foam cannon.Bottom line is that the adapter fits the pressure washer, but does not work as intended with the foam cannon.

Muy buena compra
