description Methods and apparatus for sealing a plug within tubing that the plug is designed to be landed and set in are disclosed. The plug includes a seal assembly having a seal on the plug that is acted on by a piston. Wellbore fluid pressure acts on the piston when the valve is closed, thereby moving the piston to force the seal into sealing contact with an inside surface of the tubing.
