  1. What are these used for in the pump

    Where are these used in the pump?
    Are they for the seal between the pump and water, so that the water does not get into the pump?

    1. The Yellow rings are 14 mm. Used for the high pressure hose M 22 screw on connectors.
      The Green rings are 1/4 in. Used for the Quick connect fitting on the spray tips and wand to gun connection.
      The Blue rings are 3/8 in. They fit on the high pressure hose quick connect fittings.
      The Red rings are 15 mm. Not really sure where the go.
      The black one with the screen goes on the pump inlet where your garden hose hooks up. It filters out the large debris and seals the connection.
