Abstract
A fitting assembly for joining a double containment pipe (DCP), including primary and secondary pipes, to a double containment fitting, including primary and secondary fittings, wherein the secondary fitting has a larger diameter than the secondary pipe. A sealing reducer has a larger diameter end for fitting over the secondary fitting and a smaller diameter end for fitting over the secondary pipe. The sealing reducer is fit over the secondary pipe, the primaries of the DCP and double containment fitting are joined, and then the sealing reducer is positioned over the primary joint and its smaller and larger diameter ends sealed, either by adhesive or a combination of interlocking threaded fitting components and O-rings, to the ends of the secondary pipe and secondary fitting, respectively.
