The supplier usually provides the corresponding male connector according to the customer’s standard, plus a gasket to enhance the sealing effect of the connection.

  • Mini filter 

Gravity guns usually use mini-filter at the fluid inlet or at the mouth of the spray paint cup to filter out impurities from the paint. To prevent the spray gun from clogging during use.

  • Hex wrench

The multifunctional hexagonal wrench is used at one end to remove the spray pattern adjustment knob and other parts fixed with hexagonal screws, and the other is to remove the air valve set inside the gun.
