  Fairly straight forward thing to fit. For a few pounds to resurect what was an expensive piece of kit, well worth the effort.

• Q still have leak in replaced outlet connection 3 Answers

  model 4.99 new out elbow fitted. leaking at point where elbow meets outlet pump. Ordered o ring for it. I have fitted it over the screw fit on the outlet pump. now cannot fit new elbow to pump. cannot insert metwl clamp. Any ideas? Am I puting the o ring in the correct place? Any help appreciated Bob

    As stated above you need a small O ring which doesn't come with espares part (although espares claim it comes woth all seals). I found that when I connected up to the low pressure hose the outlet connection leaked slightly so I wasn't hopeful. However when I switched on the pump the leak got worse for a second then it stopped suddenly - I assume the pressure seated the O ring properly. The sealing method is quite confusing - the outlet connection has an internal tube with an external O ring which looks like it should seal to the inner surface of the pump outlet. However it as actually much too small to do this - presumably it's for use with a different model. Incidently the pressure hose will seal directly to the pump outlet (without using the elbow) and it seals using this type of external O ring. It seems Karchner use some universal parts that seal in different ways on different models.

    Hi Bob, You need the small 'O' ring which is about the same size as the one on a male garden hose connector. It just sits on the inner pipe. The screw fitting is not actually used with this connector and (I think) was or is for a different machine using the same pump. The big orange DIY store does a pack of 'O' rings in the plumbing section for about £1.99. The one you need is in there - so is the larger one for the Inlet (clear plastic) pipe. That one sits in a groove and is easy to see! Best of luck, CJ

    The O ring fits inside the female connection of the pump so that it buts up to the elbow outlet fitting.

• Q O-ring needed or not ??? 2 Answers

  After replacing this part, anytime I hook up the pressure hose, the pressure forces water out through the other end i.e. metal c-clip end (washer is still off). Is there a seal/o-ring that I am missing at this end ?

    Nearly made the same mistake. Inside there is a small rubber O ring, luckily I saw it when it fell out but could easily have missed it.

    Yes. It is a standard size, Though I cannot remeber the actual size.

• Q Pressure Washer Outlet Connector leaks when I turn on the pump 1 Answer

  hi i have just fitted a new pressure washer oulet connector, fitted quite easily, but when i switch on the pump it leaks, but when i turn the pump off and allow the water to flow through it doesnt leak, o ring is in place too, any suggestions please

  by mark - 29 March 2011

    Hi mark, it may well be that the pump itself has become damaged or cracked - especially if the symptoms started since you started using your washer again after the winter months. Water freezing inside the pump can cause damage and leaks.

• Q does this part seal to the machine with an o ring? 1 Answer

  Karcher KB5050 needs this outlet part, it has split. There is no O ring on my machine sealing the part onto the machine, should it have one? is the seal integral to the part and machine without an o ring seal. The O ring seal you mention as not provided, is that only an O ring seal for the outlet hose to this part? Please confirm before i order.

    It certainly needs a ring, but the original ring could be stuck in the socket into which the part fits
