Old and new cup design

Diameter larger than I.D.

Diameter smaller than I.D.

Lower Cup Profile showing expansion of major diameter due to weight of plunger compressing the ring at the bottom of the cup. Once the lower cup expands and seals with the casing wall, the upper cup then expands and seals by inflation due to pressure build up in the internal chamber of the plunger.
