A reusable sealed coupling for joining a first pipe having a first internal diameter adjacent a first end thereof which is substantially equal to an outer diameter of a second pipe, the coupling comprising: a coupler capable of receiving the first end of the first pipe within a first portion thereof and an end of the second pipe within a second portion thereof so that the coupler, second pipe, and first pipe achieve mutual overlap in at least one region. The first and second pipes are both set into predetermined positions with respect to the coupler and with respect to one another; and a seal between the coupler, second pipe, said first pipe is created in at least a portion of the region of mutual overlap.
