COMPOSITE CIRCULAR CONNECTOR SEAL AND METHOD OF USE

摘要

A composite circular connector seal, or an assembly comprising a plurality of such seals, may be engineered to seal across a predetermined tolerance band for such seals by using two substantially circular seal elements sized to slidingly fit about a tubular that has a positive and negative outer diameter tolerance range, where each seal element is terminated at one circumferential edge with a packer cap, and a core element disposed intermediate the two substantially circular seal elements at their respective non-packer cap terminated circumferential edges. The two substantially circular seal elements comprise an organic thermoplastic polymer and the core seal element, which typically comprises a synthetic rubber, is also typically molded to the two seal elements at their respective non-packer cap terminated circumferential edges.

1. A composite circular connector seal, comprising a composite stack, the composite stack comprising:
a. two substantially circular seal elements, each seal element comprising an outer diameter (D) sized to slidingly fit about a tubular, the tubular comprising a positive and negative outer diameter tolerance range, and an organic thermoplastic polymer, each seal element terminated at one circumferential edge with a packer cap ; and b. a core seal element comprising an outer diameter substantially the same as the outer diameter of the two substantially circular seal elements, the core seal element disposed intermediate to the two seal elements at their respective non-packer cap terminated circumferential edges.
