Query: High pressure hose connection

I own a Karcher 3000 G pressure washer. One of the big concerns I recommend customers check prior to purchasing any pressure washer is the method used for connecting the High Pressure hose to the Pump discharge. On my Karcher 3000 G this connection is very POOR. I can not get a tight fit even after having the repair shop (recommended by Karcher) look at it. This loose fit, causes the high pressure water to leak at the joint and you can not get the full high pressure effect.
