FelPro and Asbestos-Containing Products: Exposure History and Legal Background

Company History

Fel-Pro Incorporated was a Chicago-area gasket and sealing products manufacturer that operated for much of the twentieth century as one of the United States’ leading suppliers of industrial and automotive sealing components. The company built its reputation on precision-engineered gaskets, packings, and related sealing materials sold to industrial plants, refineries, shipyards, power generation facilities, and the automotive aftermarket. Fel-Pro’s products were broadly distributed through industrial supply channels, meaning they reached worksites across virtually every major American industry during the postwar manufacturing boom.

During the decades when asbestos was the material of choice for high-temperature, high-pressure industrial applications, Fel-Pro’s product lines reflected the standard practices of the sealing and gasket industry. Asbestos fiber — prized for its heat resistance, compressibility, and chemical stability — was incorporated into many categories of gaskets and packing materials sold throughout the mid-twentieth century. According to asbestos litigation records, Fel-Pro manufactured and distributed products containing asbestos during a period spanning roughly from the 1940s through the early 1980s, when regulatory pressure and growing awareness of asbestos health hazards prompted the industry to transition toward substitute materials.

Fel-Pro was eventually acquired by Federal-Mogul Corporation, a major automotive and industrial parts manufacturer. Federal-Mogul itself later filed for bankruptcy reorganization in part due to asbestos liability associated with products manufactured by companies it had acquired, though the specific contours of liability attributable to Fel-Pro’s legacy products have been addressed through civil litigation rather than a dedicated bankruptcy trust.

Asbestos-Containing Products

Court filings document that Fel-Pro manufactured a range of sealing products that plaintiffs alleged contained asbestos fiber as a primary functional component. The product categories most frequently identified in litigation include pipe gaskets, sheet gaskets, compressed asbestos sheet packing, and related industrial sealing materials used in piping systems.

Sheet Gaskets and Cut Gaskets

Plaintiffs alleged that Fel-Pro produced compressed asbestos sheet gaskets intended for use at pipe flanges, valve bonnets, pump housings, and pressure vessel connections throughout industrial facilities. These gaskets were typically cut to shape on the job or supplied in pre-cut form and were designed to withstand elevated temperatures and pressures encountered in steam, chemical, and hydrocarbon piping systems. According to asbestos litigation records, these sheet gasket materials could contain asbestos fiber concentrations sufficient to release respirable fibers during handling, cutting, and installation.

Pipe Flange Gaskets

Among the most frequently cited Fel-Pro products in exposure litigation are spiral-wound and ring-type gaskets used at pipe flanges in industrial piping systems. Court filings document that workers in refineries, chemical plants, and power stations routinely installed, removed, and replaced these gaskets as part of routine maintenance and turnaround work. Plaintiffs alleged that the process of breaking old gaskets free from flange faces — using scrapers, wire brushes, or power tools — generated asbestos-containing dust that workers inhaled without adequate respiratory protection.

Packing Materials

According to asbestos litigation records, Fel-Pro also supplied braided and compressed packing materials used in valve stems, pump shafts, and similar rotating or reciprocating equipment. Packing materials of this type were typically installed and periodically replaced by pipefitters, millwrights, and maintenance mechanics. Plaintiffs alleged that cutting, shaping, and removing worn asbestos packing released respirable fiber into the immediate work environment.

Automotive and Small-Engine Gaskets

In addition to heavy industrial applications, Fel-Pro held a substantial share of the automotive gasket market. Court filings document that the company supplied head gaskets, exhaust manifold gaskets, and other engine sealing components to automotive shops, fleet maintenance operations, and do-it-yourself consumers. Plaintiffs alleged that mechanics who handled, compressed, or scraped these gaskets during engine repair were potentially exposed to asbestos fibers released from the gasket material.

It should be noted that the specific asbestos content, fiber type, and fiber concentration in individual Fel-Pro product formulations have been subjects of dispute in litigation. The characterizations above reflect allegations made in court filings and should not be read as established findings of fact regarding any particular product lot or formulation.

Occupational Exposure

According to asbestos litigation records, the occupations most frequently associated with Fel-Pro gasket and packing exposure include pipefitters, plumbers, steamfitters, boilermakers, millwrights, refinery maintenance workers, power plant operators, and automotive mechanics. The exposure pathways described in court filings generally fall into two categories: primary exposure among workers who directly handled the products, and bystander exposure among tradespeople working in the same areas where gasket and packing work was underway.

Industrial and Refinery Settings

Plaintiffs alleged that industrial facilities — including petroleum refineries, chemical processing plants, pulp and paper mills, and electric generating stations — used Fel-Pro gasket and packing products extensively throughout their piping systems. In these settings, turnaround maintenance events required crews to disassemble and reassemble large numbers of flanged connections over short periods, generating concentrated periods of gasket-related dust exposure. According to asbestos litigation records, workers in these environments often performed this work in confined or poorly ventilated spaces, increasing the potential for fiber accumulation in the breathing zone.

Shipyard and Maritime Applications

Court filings document that Fel-Pro gaskets and packing materials were also used aboard vessels and in shipyard facilities, where pipefitting and valve maintenance were ongoing activities. Maritime workers, including pipefitters and machinists employed in naval and commercial shipbuilding and repair, are among those who have brought claims referencing Fel-Pro products.

Automotive Repair

Mechanics who serviced engines using Fel-Pro head gaskets and related sealing components have alleged exposure through scraping and cleaning gasket surfaces during engine rebuilds. According to asbestos litigation records, this category of exposure was common in dealership service departments, independent repair shops, and fleet maintenance garages throughout the period when asbestos-containing automotive gaskets were in widespread use.

Duration and Latency Considerations

Asbestos-related diseases — including mesothelioma, asbestosis, and asbestos-related lung cancer — typically develop decades after initial exposure, with latency periods commonly ranging from fifteen to fifty years. Workers exposed to Fel-Pro asbestos-containing products during the 1950s, 1960s, and 1970s may be experiencing or receiving diagnoses of asbestos-related illness today. Family members of workers who carried asbestos dust home on their clothing may also have experienced secondary or take-home exposure, which has been the basis for claims in related litigation.

Fel-Pro does not have a dedicated asbestos bankruptcy trust fund. Unlike manufacturers that resolved their asbestos liability through Chapter 11 reorganization proceedings — which resulted in the creation of structured settlement trusts — Fel-Pro’s asbestos-related claims have been addressed through conventional civil litigation in state and federal courts.

Litigation History

According to asbestos litigation records, Fel-Pro has been named as a defendant in asbestos personal injury lawsuits filed by workers and family members alleging exposure to its gasket and packing products. Plaintiffs alleged that the company manufactured and distributed asbestos-containing products while failing to provide adequate warnings about the health hazards associated with asbestos fiber inhalation. Court filings document that these claims have been litigated across multiple jurisdictions and involve a range of alleged disease outcomes, including mesothelioma, lung cancer, and asbestosis.

Federal-Mogul Bankruptcy Context

The acquisition of Fel-Pro by Federal-Mogul is relevant background for anyone researching this exposure history. Federal-Mogul filed for Chapter 11 bankruptcy protection in 2001, citing in part asbestos liability from products manufactured by companies it had acquired. A Federal-Mogul asbestos trust was established through that bankruptcy proceeding. However, eligibility for claims against the Federal-Mogul trust depends on the specific products and entities covered by that trust’s claims matrix, and individuals researching Fel-Pro exposure should consult with an asbestos attorney to evaluate whether any Federal-Mogul trust claims may apply to their particular circumstances.

Individuals who were exposed to Fel-Pro gaskets, packing materials, or related sealing products — and who have since been diagnosed with mesothelioma, asbestos-related lung cancer, asbestosis, or other asbestos-caused conditions — may have legal options available to them.

Because Fel-Pro does not operate a standalone asbestos trust fund, claims related to Fel-Pro product exposure are typically pursued through civil litigation. An experienced asbestos attorney can evaluate the specific facts of an exposure history, identify all potentially responsible parties (which may include product manufacturers, distributors, and premises owners in addition to Fel-Pro), and determine whether any applicable trust fund claims — including potentially those related to the Federal-Mogul trust — may be available alongside civil litigation.

Workers and family members should gather and preserve all documentation they can locate, including employment records, union membership history, Social Security earnings statements, and any product identification information from worksites where exposure occurred. This documentation supports both trust fund claims and civil litigation. Given the latency period associated with asbestos disease, exposure that occurred decades ago remains legally actionable in most jurisdictions, subject to applicable statutes of limitations that vary by state and disease diagnosis date.
