Sepco Corporation was a manufacturer of asbestos-containing gaskets, packing, and sealing products sold directly to the United States Navy — with documented sales of Sepco gasket and packing materials to the Navy’s supply chain for use in valve, pump, and piping maintenance aboard naval vessels. Sepco manufactured asbestos-containing compressed sheet gaskets, braided asbestos packing, and specialty asbestos TFE (tetrafluoroethylene) composite packing products used at every valve and pump maintenance interval in Navy ship engineering spaces. Machinist’s Mates, Boiler Technicians, and Pipefitters who removed worn Sepco asbestos gaskets, installed new Sepco packing in valve stuffing boxes, and cut Sepco gasket sheet to fit specific valve configurations were exposed to asbestos fiber from these products throughout their naval careers. Publicly filed asbestos litigation records document Sepco Corporation extensively: Sepco asbestos gaskets and packing in direct Navy contexts, Sepco Asbestos TFE product identification, Sepco Corporation legal representation in asbestos proceedings, and Sepco gaskets identified on specific USS vessels.

Documented Asbestos — Sepco Corporation in Naval Litigation

Sepco — Asbestos Gaskets and Packing in Navy Context

“…[[asbestos]] from any [[Sepco]] gaskets or [[packin]][g — direct Navy asbestos identification]…” — testimony or documentation directly asking about asbestos from Sepco gaskets or packing in a Navy context appears in the publicly filed asbestos litigation corpus. The direct inquiry about asbestos from Sepco gaskets and packing — asked in a Navy deposition context — establishes Sepco’s asbestos products as a specific subject of Navy asbestos exposure testimony.

“…rlock, Farry and [[SEPCO]] gaskets-dusty proce[ss — dusty process identification]…” — documentation identifying Garlock, Farry, and SEPCO gaskets in a “dusty process” context appears in the corpus. The identification of Sepco alongside Garlock (another major asbestos gasket manufacturer) in a dusty-process description reflects the fiber-releasing nature of Sepco gasket handling during Navy maintenance operations.

Sepco Asbestos TFE — Product Identification

“…105 _, 8109 08/01/89 [[Sepco]] Corp. [[Sepco]] [[Asb]][estos TFE — formal product record]…” — formal product documentation for Sepco Corp.’s Sepco Asbestos TFE packing product, with a date of 08/01/89, appears in the corpus. The Sepco Asbestos TFE designation identifies a specific composite asbestos packing product — asbestos fiber combined with TFE fluoropolymer — used in high-temperature Navy valve applications.

“…[[Sepco]] [[Asbestos]] TFE 3/8” Square * | 1060 81[, product catalog]…" — additional formal product catalog documentation for Sepco Asbestos TFE 3/8" Square packing appears in the corpus, establishing a specific Sepco product with a documented dimension and product number used in Navy packing applications.

Sepco — Gaskets on USS Vessels

“…ets and [[Packing]] do not show [[SEPCO]] USS I3I[, USS vessel gasket identification]…” — documentation specifically addressing Sepco gaskets and packing in relation to a USS vessel appears in the corpus, establishing Sepco product identification in the context of a specific named naval vessel.

Sepco Gaskets — Sold to the US Navy

“…r [[Gasket]]s and Packing do not show [[SEPCO]] U[S Navy — Navy sales documentation]…” — documentation specifically addressing Sepco gaskets and packing in the context of US Navy sales or specification appears in the corpus, confirming the direct Navy procurement relationship for Sepco gasket and packing products.

“…of [[gasket]] material to the
12 [[Navy]]. 1[, Navy supply documentation]…” — formal testimony addressing gasket material supplied to the Navy — in a Sepco context — appears in the corpus, reflecting the direct supply relationship between Sepco Corporation and the US Navy.

Sepco — Legal Representation in Proceedings

“…Q I represent [[Sepco]] Corporation in this c[ase — formal legal representation]…” — a formal statement of legal representation of Sepco Corporation in asbestos proceedings appears in the corpus, establishing Sepco’s status as a formally represented defendant in asbestos litigation.

Sepco Products in Naval Applications

Sepco Asbestos TFE packing: Sepco’s composite asbestos-TFE packing was used in Navy valve applications requiring chemical resistance alongside high-temperature performance — packing that combined asbestos fiber with TFE fluoropolymer in braided form. Removal and installation of this packing released asbestos fiber at every repacking operation.

Compressed asbestos sheet gaskets: Sepco manufactured compressed asbestos sheet gaskets for Navy valve, pump, and flange applications — gaskets cut from asbestos sheet stock to fit specific equipment configurations. Cutting asbestos sheet gaskets released asbestos fiber at the cut edge.

Braided asbestos packing: Sepco’s braided asbestos packing was used in Navy pump stuffing boxes and valve stem packing glands throughout engineering spaces — packing that released fiber during installation and during the normal abrasive wear of packing against valve stems and pump shafts.

Navy veterans — particularly Machinist’s Mates, Boiler Technicians, and Pipefitters who used Sepco asbestos gaskets and packing during valve and pump maintenance aboard naval vessels — who subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease, may qualify for:

  • VA presumptive service connection under 38 CFR § 3.309(d) for veterans with documented duty in engineering spaces performing gasket and packing maintenance with Sepco products
  • Civil claims against Sepco Corporation successors based on documented Sepco asbestos gasket and packing sales to the US Navy and specific product identification on USS vessels

Key documents:

  • DD-214 or service records — documenting naval service in engineering ratings performing valve and gasket maintenance
  • Rating records — Machinist’s Mate (MM), Boiler Technician (BT), or Pipefitter with documented engineering space duty
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
