ABSTRACT:
A cylindrical central high-strength pipe, normally a custom extrusion of PVC, mounts caps, preferrably of high-strength Rhinite.TM. plastic, at both ends so as to create an interior reservoir that is capable of being pressurized to a working pressure of 230 P.S.I. and a burst pressure in excess of 600 P.S.I. Each end cap, permanently affixed to the pipe end by gluing, includes a cylindrical outer sleeve extending beyond the pipe end and presenting in its extension a circular interior groove. A circular plug, again preferably made from Rhinite.TM. plastic, is inserted into the sleeve extension to form a pressure tight seal against a circular gasket, preferably a robust one eight inch (1/8") thickness "O"-ring. A retaining ring, preferably made of Delrin.TM. plastic, that is expandable and contractible in circumference is inserted in the circular interior grove of the sleeve and against the plug, therein to make that the reservoir is capable of being pressurized. Complimentary beveled surfaces on the plug and the retaining ring serve to forcibly hold both in position against pressure forces within the reservoir.
