Chicago Gasket Company: Asbestos Product History and Occupational Exposure Reference

Company History

Chicago Gasket Company operated as an American manufacturer and supplier of industrial sealing products, including gaskets and packing materials used across a broad range of heavy industries throughout much of the twentieth century. The company served commercial and industrial markets during an era when compressed asbestos fiber was considered the standard material for high-performance sealing applications. Asbestos was prized by gasket and packing manufacturers for its resistance to heat, chemical corrosion, and mechanical compression — properties that made it nearly indispensable in industrial environments where steam, pressure, and caustic substances were constant factors.

According to asbestos litigation records, Chicago Gasket distributed its products to facilities including refineries, chemical plants, shipyards, paper mills, and manufacturing operations across the United States. The company’s products were designed for use in piping systems, pumps, valves, heat exchangers, and other equipment operating under demanding temperature and pressure conditions. During the period roughly spanning the 1940s through the early 1980s, many of the gasket and packing products sold into these markets by manufacturers like Chicago Gasket contained asbestos as a primary functional component.

The company’s founding date is not definitively established in publicly available records. What is documented through litigation and industry history is that Chicago Gasket participated in a market that supplied asbestos-containing sealing products to American industry during the decades when asbestos use was at its height. The company is reported to have ceased the use of asbestos in its products in approximately the early 1980s, consistent with broader regulatory pressure and the industry-wide transition toward non-asbestos substitute materials that followed mounting scientific and regulatory scrutiny of asbestos hazards throughout the 1970s.

Asbestos-Containing Products

Plaintiffs alleged in various legal proceedings that Chicago Gasket manufactured and sold gaskets and packing products containing asbestos fiber during the mid-to-late twentieth century. While specific named product lines attributed to Chicago Gasket are not catalogued in the same detail as those of some larger national manufacturers, court filings document the company’s involvement in supplying asbestos-containing sealing materials to industrial buyers.

Gaskets and packing materials containing asbestos were among the most widely distributed asbestos-containing products in American industry. Compressed asbestos sheet gaskets — sometimes referred to as full-face or ring gaskets — were cut from large sheets of material composed of asbestos fiber bound with rubber or other binders. These gaskets were installed between pipe flanges, on valve bonnets, on pump casings, and in heat exchanger assemblies throughout industrial plants. Braided and woven asbestos packing was similarly installed in valve stems, pump shafts, and other rotating or reciprocating equipment to prevent fluid leakage.

According to asbestos litigation records, the asbestos content of compressed sheet gasket materials used in industrial applications during this era typically ranged from a substantial minority to a majority of the total material by weight, depending on the grade and intended application of the product. This asbestos fiber was often chrysotile, though some specialty products incorporated amphibole asbestos varieties for applications requiring resistance to specific chemicals or extreme temperatures.

The hazard associated with these products arose not merely from their manufacture but from their routine installation and removal in the field. Cutting sheet gaskets to fit specific flanges — a task routinely performed by pipefitters and mechanics directly at the jobsite — generated asbestos dust. Similarly, the removal of old gaskets and packing from equipment surfaces, often requiring scraping, wire brushing, or powered abrasive tools, released asbestos fibers in concentrations well in excess of what is now recognized as safe. Court filings document these work practices as central to the exposure claims raised by workers who handled gasket and packing products from suppliers including Chicago Gasket.

Occupational Exposure

The workers most likely to have encountered Chicago Gasket products during the company’s operational years were those employed in industries that relied heavily on piping systems and pressurized equipment. Plaintiffs alleged that occupational groups including the following sustained exposure to asbestos from gasket and packing products during routine job duties:

  • Pipefitters and steamfitters, who installed, maintained, and replaced gaskets and valve packing throughout industrial piping systems
  • Boilermakers, who worked with high-pressure steam systems requiring asbestos-rated sealing components
  • Millwrights and maintenance mechanics, who serviced pumps, compressors, and other rotating equipment packed with asbestos materials
  • Refinery workers and chemical plant operators, who worked in environments where asbestos-containing gaskets and packing were standard maintenance supplies
  • Shipyard workers, who installed and maintained piping, valves, and mechanical systems aboard vessels during construction and overhaul
  • Paper mill and power plant workers, who operated in facilities with extensive steam and process piping requiring regular gasket and packing maintenance

According to asbestos litigation records, a critical and often underappreciated aspect of gasket and packing exposure involved secondhand or bystander contact. Workers who were in proximity to pipefitters or mechanics performing gasket work — without themselves directly handling the materials — could nonetheless inhale asbestos fibers released into shared work spaces. In enclosed spaces such as ship engine rooms, below-deck compartments, or confined industrial areas, fiber concentrations could accumulate rapidly during maintenance activities.

The latency period between initial asbestos exposure and the development of asbestos-related disease is characteristically long — often ranging from twenty to fifty years. This means that workers exposed to asbestos-containing gaskets and packing products during the 1950s, 1960s, and 1970s may only now be receiving diagnoses of mesothelioma, asbestos-related lung cancer, or asbestosis. Family members of workers who carried asbestos dust home on their clothing and skin may also have sustained secondary exposure, a recognized pathway for disease documented in medical and legal literature.

Court filings document that the gasket and packing trades were among the highest-exposure occupational categories in the broader landscape of asbestos-related disease claims, in part because the work of cutting, fitting, and removing asbestos-containing sealing materials was physically disruptive, performed in close proximity to the worker’s breathing zone, and repeated across an entire working career.

Trust Fund / Legal Status

Chicago Gasket has been named as a defendant in asbestos personal injury litigation. However, the company does not appear to have established a dedicated asbestos bankruptcy trust fund. This means that individuals asserting claims related to Chicago Gasket products must pursue those claims through the civil litigation system rather than through an administrative trust claim process.

According to asbestos litigation records, the company has faced allegations from former industrial workers and their families who attributed asbestos-related diagnoses in part to exposure from Chicago Gasket gaskets and packing materials. Plaintiffs alleged that these products were used at their worksites during the period in which the company was distributing asbestos-containing sealing materials to industrial customers.

It is important to note that Chicago Gasket is not the only potential source of legal accountability for workers who handled asbestos-containing gaskets and packing on the job. In most industrial settings, gaskets and packing from multiple manufacturers were used concurrently or over time. Many of those other manufacturers — including larger national suppliers of compressed asbestos sheet and packings — did establish bankruptcy trusts following Chapter 11 reorganizations. Workers with documented exposure to multiple asbestos-containing products may have viable trust claims against those other manufacturers even where their Chicago Gasket-related claims proceed through traditional litigation channels.

If you or a family member worked in an industry where gaskets and packing materials were routinely installed and replaced — including refinery work, shipbuilding, power generation, chemical processing, or industrial piping trades — and have received a diagnosis of mesothelioma, asbestos-related lung cancer, or asbestosis, the following information is relevant to your situation:

  • Chicago Gasket does not maintain an asbestos bankruptcy trust fund. Claims involving this company are pursued through civil litigation, not through an administrative claims process.
  • Other gasket and packing manufacturers established trust funds that may be accessible depending on your documented exposure history. An attorney experienced in asbestos claims can identify which trusts may apply to your situation.
  • Exposure documentation matters. Work history records, union records, Social Security earnings records, coworker affidavits, and facility records can all help establish the products present at specific worksites during specific periods.
  • Time limits apply. Statutes of limitations for asbestos personal injury claims vary by state and by the date of diagnosis. Acting promptly after a diagnosis is important to preserving legal options.
  • No cost to investigate. Asbestos personal injury attorneys typically work on a contingency fee basis, meaning there is no out-of-pocket cost to have your exposure history reviewed and your legal options assessed.

Workers and families researching asbestos exposure history related to Chicago Gasket and similar industrial gasket and packing suppliers are encouraged to consult with legal counsel who specializes in occupational asbestos disease to obtain guidance specific to their circumstances.
