An oilfield tubular, such as a stinger (), designed to be installed in a tubing hanger () in an XMT (Christmas tree) located on the sea bed, is presented. The oilfield tubular () is exposed to the production bore () pressure, and includes axial sealing means () located on an end () of the tubular (). The axial sealing means () includes a metal c-ring seal (), which metal c-ring seal () is smaller in cross section than the thickness (t) of the oilfield tubular wall (). The opening () of the metal c-ring seal () is facing the high pressure side of the production bore (). This pressure tend to expand the c-profile to firm engagement with contacting surfaces.
