Abstract: A connector system includes a fitting body (104) and a union nut (106). A cutting ring (102) is disposed proximate within the fitting body and union nut. The cutting ring includes a first end (136) engaging with the fitting body and having at least one cutting edge, a second end engaging with the union nut, and a radially extending collar (140) disposed between the first end and the second end. The collar having an annular radial surface facing the first end and an annular groove (144) is defined within the radial surface. A cylindrical outer surface having a first diameter is disposed between the radial surface and the first end, and a transition area is defined from the outer surface towards the radial surface. The transition area being angled radially inward such that the transition area has a second diameter that is less than the first diameter. An elastomeric seal (146) is disposed within the annular groove.
