A pipe adapter including an inner tube member, a fastener member, an outer sleeve member, a compressible sleeve member, and a fitting member. The fastener member may have threads on an inner diameter adapted to matingly engage a threaded portion of the inner tube member along a proximal section thereof. The outer sleeve member may girdle the inner tube member and connect to and extend outwardly from the fastener member. The compressible sleeve member may be configured as at least one ring positioned to overlie the outer tube member. The fitting member may connect to a distal section of the inner tube member. At least a portion of at least one of the fitting member and the compressible sleeve member may be positionable within a portion of a pipe. The compressible sleeve member may extend outwardly from a longitudinal axis of the inner tube member toward the pipe.
