A tubular connection has first and second tubular members having aligned bores with a common axis and having first and second seal surfaces, respectively. A metal seal has a first end portion that sealingly engages the first seal surface and a second end portion that sealingly engages the second seal surface. The metal seal has a sidewall with at least two folds. One of the folds defines an axial interior gap. The other of the folds defines an axial exterior gap. An exterior spacer member is positioned in the exterior gap to limit closer of the exterior gap in response to a greater pressure on the interior of the seal than on the exterior. An interior spacer member is positioned in the interior gap to limit closure of the interior gap in response to a greater pressure on the exterior of the seal than on the interior.
