Abstract
A metal-to-metal packer seal for downhole use in a well that operates in a deleteriously corrosive atmosphere. The seal is formed by the cooperating ends of two pipe sections, one of which is vertically positioned in a well with an upwardly facing metallic socket. The corresponding upper pipe section includes a connector which is lowered onto the socket and carries with it at least one, and preferably a plurality of metal rings which are extruded to form a corrosive resistant circular seal between the engaged pipe socket and pipe connector.
