A light weight filament wound pressure vessel. The vessel includes a central cylindrical shell and a pair of end caps adapted to fit into the opposite ends of the shell. Each of the end caps includes a convex, dome-like upper portion, a cylindrical skirt depending from the upper portion and integrally connected thereto, and an annular land connected to the edge of the cylindrical skirt. The cylindrical skirts are of substantially the same outer diameter as the central shell. The lands have an outer diameter which is slightly less than the inner diameter of the central shell so that the junction between the lands and the skirt forms a shoulder having a radial dimension substantially equal to the thickness of the central shell. Each land has an annular groove therein for carrying a resilient O-ring. The O-rings are of a slightly larger diameter than the outer diameter of the lands so that they sealingly engage the inner wall of the central shell when the lands are inserted into the central shell. The central shell and cylindrical skirts of the end caps form a smooth external junction. The assembly is overwound with a fiberglass filament to provide the desired bursting strength of the vessel. The lands may be integrally connected to the skirts or mounted on a collector ring. In one embodiment of the pressure vessel of this invention a fluid flow directing means is integrally connected to the internal surfaces of one of the end caps for guiding fluids through the vessel and eliminating "channeling." This embodiment of the invention is particularly adapted for use as a water conditioning tank.
