A composite circular connector seal configured to seal on an outer surface of a tubular and be actuated by longitudinal compressive loading, comprising a composite stack, the composite stack comprising: a. two circular seal elements, each circular seal element comprising a non-packer cap terminated circumferential edge disposed at an axial end of the non-packer cap, a packer cap terminated circumferential edge disposed at an axial end of the packer cap where the packer cap terminated circumferential edge is disposed axially opposite the non-packer cap terminated circumferential edge, and a U-shaped cross-section defining a seal element inner channel, each circular seal element terminated at the packer cap terminated circumferential edge with a packer cap dimensioned to provide a U-shaped cross-section defining a packer cap inner channel which receives the packer cap terminated circumferential edge, each circular seal element comprising: 1. an inner diameter sized to slidingly fit about the outer surface of the tubular, the tubular comprising a positive and negative outer diameter tolerance range; 2. an organic thermoplastic polymer; and 3. an inner surface configured to be concentrically oriented along a common axis to the outer surface of the tubular; and b. a core seal element comprising an inner and an outer diameter the same as corresponding inner and outer diameters of the two circular seal elements, the core seal element disposed intermediate to the two circular seal elements at their respective non-packer cap terminated circumferential edges within each circular seal element's inner channel such that each circular seal element envelops a different axial end of the core seal element, the core seal comprising an inner surface configured to be oriented parallel to the outer surface of the tubular, the core seal element sufficiently deformable under longitudinal compressive load to fill a seal gap between the outside surface of the tubular and an inside of a housing in which the tubular is deployed and create a positive seal which statically seals on the outer surface of the tubular. a. two circular seal elements, each circular seal element comprising a non-packer cap terminated circumferential edge disposed at an axial end of the non-packer cap, a packer cap terminated circumferential edge disposed at an axial end of the packer cap where the packer cap terminated circumferential edge is disposed axially opposite the non-packer cap terminated circumferential edge, and a U-shaped cross-section defining a seal element inner channel, each circular seal element terminated at the packer cap terminated circumferential edge with a packer cap dimensioned to provide a U-shaped cross-section defining a packer cap inner channel which receives the packer cap terminated circumferential edge, each circular seal element comprising: 1. an inner diameter sized to slidingly fit about the outer surface of the tubular, the tubular comprising a positive and negative outer diameter tolerance range; 2. an organic thermoplastic polymer; and 3. an inner surface configured to be concentrically oriented along a common axis to the outer surface of the tubular; and 1. an inner diameter sized to slidingly fit about the outer surface of the tubular, the tubular comprising a positive and negative outer diameter tolerance range; 2. an organic thermoplastic polymer; and 3. an inner surface configured to be concentrically oriented along a common axis to the outer surface of the tubular; and b. a core seal element comprising an inner and an outer diameter the same as corresponding inner and outer diameters of the two circular seal elements, the core seal element disposed intermediate to the two circular seal elements at their respective non-packer cap terminated circumferential edges within each circular seal element's inner channel such that each circular seal element envelops a different axial end of the core seal element, the core seal comprising an inner surface configured to be oriented parallel to the outer surface of the tubular, the core seal element sufficiently deformable under longitudinal compressive load to fill a seal gap between the outside surface of the tubular and an inside of a housing in which the tubular is deployed and create a positive seal which statically seals on the outer surface of the tubular.
