Liquid Dispenser Barrel Adapter

The adapter assembly consists of a clear tubing with an adapter head on one end (which holds the barrel) to an adapter tab on the other end which fits into the dispenser controller. The adapter assembly that connects the barrel to the controller delivers the air supply to the piston inside the syringe. The piston pushes the material forward and, using vacuum, pulls back to control dripping. O rings in the adapter head keep the syringe snug.
