Abstract: A method of forming a floating piston includes fabricating a piston cup, wherein the piston cup includes a top, a sidewall void of any seal-gripping irregularities, and an open end, and forming an elastomer seal over the sidewall of the piston cup. A floating piston includes a piston cup having a top, a sidewall extending about the periphery of the top and an open end, wherein the sidewall is void of any seal-gripping irregularities; and an elastomer seal formed about the sidewall of the piston cup.
