      Unscrew or remove the current pressure washer fitting from your pressure washer unit.

    • 2

      Measure the length of the fitting, or thread.

    • 3

      Measure across the opening of the fitting, where it fits onto the pressure washer unit.

    • 4

      Compare your measurements to charts that indicate the size of the thread of pressure washer fittings.
