This is a plastic part that attaches the pump to the elbow - see #26 on the diagram

Fits many Karcher gas pressure washers including GH2800.

Char's part note:  some dealers are selling a Karcher part under this number that is a water inlet kit.  Karcher may have changed numbers at some point, but this part is not a water inlet kit - it's a single black plastic part that threads the elbow to the pump on some Karcher gas pressure washers
