A Y-shaped sealing ring gasket for use in sealing the coupled ends of pipe lengths is disclosed wherein the sealing ring gasket is secured within a bell end or coupling collar on one end of a pipe and is adapted to be deformed by the spigot end of a pipe received within the bell or collar to form a seal affording increased sealing pressure when the sealing ring is subjected to hydrostatic pressure.
