The Piston Head is located inside the Main Cylinder. The Piston Head has two O-rings (sold separately) which create a seal in order to keep the product from leaking out of the Main Cylinder. Once the product is drawn through the Rotary Valve and into the Main Cylinder the Piston Head will then push the product back through the Rotary Valve and out through the Dispensing Nozzle and into the product container.
