A high pressure accumulator is disclosed which includes a housing having walls defining a chamber and a piston residing in the chamber. The piston is comprised of polyphenylene sulfide and preferably includes a head portion and wall portions extending away from the head portion. The wall portions preferably include outer and inner surfaces which are oblique. Preferably the polyphenylene sulfide includes glass fibers and minerals and is formed using injection molding techniques. The material composition of the piston and its geometrical definition give it the ability to operate when exposed to the brake fluid and when exposed to operating pressures is the range of 100 bars.
