Injection molded cold-expansion compression collar

A compression collar for reinforcing an interference fit between an end of a pipe and a fitting, the compression collar comprising:

• an injection molded tubular body formed of a cold-expansion material, the tubular body having a first end including a first opening defined therein, a second end opposite the first end and including a second opening defined therein, a central axis extending axially through the first end and the second end along a length of the tubular body, a radially inner surface defining a bore extending along the central axis through the tubular body, a radially outer surface extending linearly along a majority of the length of the tubular body, and at least one positioning tab positioned adjacent the stop end and formed as a unitary part with the tubular body, the positioning tab extending radially inwardly toward the central axis, the positioning tab having an end face and a stop face opposite the end face, wherein the compression collar is structurally configured such that the compression collar is formed without and includes no knitlines, wherein each of the radially inner surface and the radially outer surface has a substantially constant radius along the central axis between the pipe insertion end and the stop end such that the compression collar is a straight member.
