Abstract
A hydraulic coupling that is used for connecting hydraulic tubular lines includes a male plug which will mate with a standard tube end flare. The male plug has a rounded end that will provide for a line contact with the interior surface of the standard flare. The rounded end of the plug is joined to the main portion of the male plug body through a wall that is controlled in cross-sectional size so that the outer end will deflect as the male plug is tightened into place. This will provide a resilient loading along a line of contact to insure that the seal is maintained even if there is slight axial movement between the flare and the male plug.
