16. A stress relief adapter system, comprising:
a cylindrical conduit comprising:
a first end;
a second end;
a first central passage extending from the first end to the second end;
a first central longitudinal axis extending along the central passage;
an exterior surface; and
a plurality of annular grooves formed in the exterior surface and extending circumferentially about the first central longitudinal axis;
an adapter removably secured to the one of the first end or the second end of the conduit, the adapter comprising:
an interior surface defining a second central passage;
a second longitudinal axis extending along the second central passage;
a plurality of ribs formed on the interior surface, the plurality of ribs extending circumferentially about the second longitudinal axis, each of the plurality of ribs being received into one of the plurality of grooves of the cylindrical conduit;
an end portion disposed at a first end of the adapter, the end portion including:
a plurality of axially extending platforms;
an annular ring portion coupled to ends of the plurality of axially extending platforms; and
a plurality of apertures formed between adjacent platforms, the plurality of apertures being circumferentially arranged about the second central longitudinal axis and extending transversely relative to the second central longitudinal axis;
a first grooved portion disposed adjacent to the end portion, the first rooved portion including:
a first annular groove formed in an exterior surface of the adapter and extending circumferentially about the second longitudinal axis, the first annular groove having a first diameter; and
a tapered portion formed at a second end of the adapter, the tapered portion tapering inwardly along the second longitudinal axis from the first grooved portion to the second end of the adapter; and
a clamp received into the first annular groove of the first grooved portion.
