  • Face seal fitting having a polyimide sealing component for facilitating a face seal
    Patent number: 11598422
    Abstract: A face seal fitting operable to join first and second conduits together and to provide a face seal, the face seal fitting comprising a body comprising a fluid passageway, and a coupling portion having an end defining a mating face; a gland comprising a fluid passageway, and an end having a mating face operable to be seated against the mating face of the body; a polyimide sealing component configured to be situated between the body and the gland; and a compression nut fittable over the gland and coupleable to the body, the compression nut being operable, upon torqueing to achieve a threshold compression load, to cause the mating face of the gland to seat against the mating face of the body, and to compress and elastically deform the polyimide sealing component to be flush with the mating faces of the body and the gland to form a face seal.
