    Make sure you have a Torx Head screwdriver set to hand!

    I had to phone the helpline to be sure this was the right part for my pressure washer. It was unclear which number was the serial number. The new elbow assembly appeared slightly bigger than the original. It would help to be advised that you would also need a Torx Head Screwdriver set to fix your washer. The video clip on fixing it was not helpful, as it was a totally different washer. The part itself was a perfect fit. Next winter I will make sure to store my pressure washer where it will not suffer frost damage again.

  • I cannot find the release clip for the Inlet Elbow on my K4.99, do I need to try something else? By Barrie - Norwich - 02 May 2011

    Hi bert, the inlet fits in the same was as the video above, but rather than a clamp holding it in to place, the cover acts as the clamp.

    Hi, Here is a short video on our website showing how to remove the Inlet and Outlet Connector on a Karcher 3 series. However the process should be fairly similar.
