I need to order another fitting for it but don't know the exact name for it. Its the plastic peice that i screw my garden hose into that has a quick disconnect on the other end to connect to the pump.
Since there are a number of different "quick disconnect" coupling systems used by various manufacturers, you need to start by identifying the manufacturer of the pressure washer, if they provided the fitting with the new system, or the fitting manufacturer if the pressure washer manufacturer did not supply the fitting with the pressure washer. The fitting/coupling will likely have a manufacturers name / mark and model / part number on it.
The pressure washer manufacturer will likely have a web site (which you find by using the brand name to find their main web site) that sells replacement parts, but you will need their model number (or be able to identify the unit visually) in order to choose the right unit from which to choose / identify a component.
The garden hose is on the water "supply side" of the pressure washer, should that come up when trying to identify the components.
