The Apollo Air Feed Connector (stem) is used to connect the air hose (tubing) from the cup to the spray gun.  The connector will need to be threaded into the hole located just behind the trigger screw on the side of the spray gun body (remove the stainless-steel screw from this hole if there).  Once the air feed connector is installed and the air hose is connected, it will allow the spray gun to supply air pressure to the cup to pressurize it.

The Apollo spray gun air feed connector is compatible with the following Apollo spray gun models listed below:

• Apollo Spray Gun Model 5000 Series
• Apollo Spray Gun Model 5500 Series
• Apollo Spray Gun Model 7500 Series
• Apollo Spray Gun Model 7700 Series

For more detailed information on the spray gun such as parts, setup & maintenance, please review the spray gun manual and part sheet.  Note, this is interchangeable for the A7523.
