Important - Please Note:

  • This is version 1 and fits into the pump and held in with the metal cover

      I cannot find the release clip for the Inlet Elbow on my K4.99, do I need to try something else?

      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.

      You need to replace either the hose or the elbow depending on where the damage is. See the video on this part.

  • Q wrong elbow inlet part for K3.99M? 1 Answer

    This part does not fit although your website says it is the right part. The video you show to install it shows the actual identical correct part which is slightly different from the one you supplied.
