This invention relates to a fluid sealing mechanism for the inside diameter and or the outside diameter of a piston-cylinder arrangement. This device results in zero seal leakage path with low differential seal pressure required using only one piston ring, one ring groove, and very loose dimensional tolerances required on both the ring and related groove. This yields an inexpensive more positive seal for fluid piston-cylinder configuration used in industrial, commercial, and personal use.
