A sealing element system for a downhole packer reduces the tendency of the elements to extrude. Mechanical limits are provided to the amount of force that can be passed onto the uppermost and lowermost components of a sealing element system by providing a limit on the longitudinal compression available against a gauge ring. The gauge rings are roughened to also grab the uppermost and lowermost elements to fight the tendency to extrude. The uppermost and lowermost elements are configured with an external groove to control the way they deform into a sealing relationship with the tubing and casing so that extrusion into the gap is reduced.
