Abstract
A fitting body is provided with a lip that protrudes radially from at least one of the side walls of the seal groove in the sealing face toward the other side wall to form an undercut whereby an annular seal is trapped axially behind the lip to prevent the annular seal from falling out of the groove. The lip is formed by forming the fitting body with a ledge that is integral with the fitting body and protrudes axially from the sealing face adjacent one of the side walls of the groove in the sealing face. The ledge is then flattened to form the lip and an annular seal such as an elastomeric O-ring seal is then inserted into the groove with the annular seal being mechanically trapped axially behind the lip to prevent the annular seal from falling out of the groove.
