a wrap wrapped around a pipe outer surface to form a repair sleeve having a first termination section and a second termination section; and
a first termination enclosure enclosing the first termination section to form a first pressure containing connection with the repair sleeve, wherein the repair sleeve is configurable in a leak path configuration where the repair sleeve forms a leak flow path extending from a pipe defect covered by the repair sleeve to the first termination enclosure and sealed from an external atmosphere by the first termination enclosure, the first termination enclosure including:
a first outer seal disposed around the pipe on a pipe outer surface, the first outer seal outwardly spaced from the first termination section to annularly seal on the pipe outer surface; and
a first inner seal disposed around the repair sleeve on a repair sleeve outer surface, the first inner seal inwardly spaced from the first outer seal to annularly seal on the repair sleeve outer surface.
