River City Enterprises has been offering piston bins since 1986. The 400 gallon poly piston bin is now widely used in North America, Europe, and many other parts of the world for lubricating greases, automotive undercoatings, silicon adhesives, and other viscous products. The light weight piston bin became popular because it provided a simple and justifiable solution for handling viscous products. One bin replaces up to eight drums, and the air-tight seal assists in the discharge of viscous materials while maintaining product integrity. The piston bins are reusable and returnable containers that are virtually 100% efficient. They eliminate the high cost of drum waste, handling and disposal.
