Abstract: The present application provides a static seal assembly for a rod configured for reciprocal motion. The static seal assembly is generally sized to fit within a conventional cup of a stuffing box. The static seal assembly has a body with a base and a balloon that fit within the cup. The balloon is made of an expandable material and is selectively in fluid communication with a pressurized fluid source. When pressurized, or inflated, the balloon expands and forms a seal interface with the outer surface of the rod.
