ABSTRACT:
A termination fitting for use with a double containment system includes an inner segment of pipe and an outer termination cap. The outer termination cap has an open first end and an open second end, and the open second end is threaded. The inner segment of pipe extends through the open ends of the outer termination cap so that the inner segment of pipe and the outer termination cap are coaxially arranged. The termination fitting further includes a sealing collar having an inner surface secured in a fluid-tight manner to an outer sidewall of the inner segment of pipe, and an outer threaded surface threaded within the threaded open second end of the outer termination cap to close the second end and provide a high-pressure, fluid-tight seal between the open second end of the outer termination cap and the inner segment of pipe.
