Lamons Gasket Company: Asbestos-Containing Products and Occupational Exposure History

Lamons Gasket Company was a Houston-based industrial gasket manufacturer that supplied sealing products to some of the most intensive industrial environments in the United States. For decades, the company’s gaskets were standard components in Gulf Coast refineries, petrochemical complexes, and chemical processing facilities — industries where reliable, high-temperature sealing was essential to daily operations. According to asbestos litigation records, a significant portion of Lamons’ product line manufactured before 1986 incorporated chrysotile asbestos as a functional material, exposing generations of pipefitters, millwrights, boilermakers, and maintenance workers to asbestos fibers in the course of ordinary job duties.

Company History

Lamons Gasket Company was founded in 1948 in Houston, Texas, positioning itself at the center of one of the most rapidly expanding industrial corridors in postwar America. The Gulf Coast petrochemical and refining industry was undergoing dramatic growth during this period, driving substantial demand for precision sealing components capable of withstanding high temperatures, aggressive chemicals, and extreme pressure differentials.

Lamons grew alongside this industrial expansion, becoming a recognized supplier to refineries, chemical plants, and processing facilities across Texas, Louisiana, and beyond. The company’s geographic location gave it close logistical ties to major industrial customers, and its products became common components in the piping systems, pressure vessels, heat exchangers, and flanged connections that characterized mid-century industrial infrastructure.

Asbestos was a widely used industrial material during Lamons’ formative decades. Its heat resistance, compressibility, and chemical durability made it an attractive filler and sheet material for gasket manufacturing. Lamons incorporated asbestos into multiple product lines throughout the 1950s, 1960s, 1970s, and into the mid-1980s. The company reportedly ceased asbestos use in its manufacturing processes by 1986, consistent with broader industry transitions driven by mounting regulatory pressure and evolving awareness of asbestos-related health risks.

Asbestos-Containing Products

According to asbestos litigation records, Lamons Gasket Company manufactured and distributed several product types that incorporated asbestos as a raw material. Plaintiffs alleged that chrysotile asbestos was used as the filler component in spiral-wound metallic gaskets and as the base material in compressed sheet gaskets produced during the covered manufacturing period.

Lamons Spiral-Wound Metallic Gaskets with Asbestos Filler (1950s–1986)

Spiral-wound gaskets are constructed by alternating strips of metal and soft filler material, wound together to form a resilient sealing element. Court filings document allegations that Lamons’ spiral-wound metallic gaskets manufactured before 1986 used chrysotile asbestos as the filler material wound between the metal layers. These gaskets were widely used in high-temperature and high-pressure piping systems in refineries and petrochemical plants. When cut, removed, or disturbed during installation or maintenance, plaintiffs alleged that asbestos-containing filler material could release airborne asbestos fibers.

Lamons Flexitallic-Equivalent Spiral Wound Gaskets

Lamons produced spiral-wound gaskets in configurations comparable to those manufactured under the Flexitallic brand — a widely recognized standard in industrial sealing. According to asbestos litigation records, these products were distributed to many of the same industrial facilities and used in substantially identical applications. Plaintiffs alleged that these gaskets similarly incorporated asbestos filler material in their construction prior to the company’s cessation of asbestos use.

Lamons Ring-Type Joint Gaskets

Ring-type joint (RTJ) gaskets are solid metal sealing components used in high-pressure flange connections, particularly common in oil and gas production and refining environments. Court filings reference Lamons ring-type joint gaskets in the context of industrial exposure claims, though the specific asbestos content of these products is described differently across various litigation records. Workers handling flanged connections where RTJ gaskets were installed may have also encountered asbestos from companion gasket materials used in adjacent piping systems.

Lamons Compressed Asbestos Sheet Gaskets

Compressed asbestos sheet gaskets — sometimes called “sheet packing” or “compressed fiber gaskets” — were fabricated from asbestos fibers combined with rubber binders and other materials, then compressed into sheet form for cutting to custom shapes. Plaintiffs alleged that Lamons manufactured compressed asbestos sheet gaskets that were used across a broad range of industrial applications. Court filings document that workers who cut, trimmed, or fabricated custom gaskets from compressed asbestos sheet material were exposed to asbestos fiber release during that process.

Occupational Exposure

The industrial environments where Lamons products were most heavily distributed — Gulf Coast refineries, petrochemical plants, chemical processing facilities, and related heavy industries — were among the most asbestos-intensive workplaces in the United States during the mid-twentieth century. Workers in these settings encountered Lamons gaskets not as isolated components but as part of a dense industrial environment in which asbestos-containing materials were present throughout the work environment.

According to asbestos litigation records, the following occupational groups have been identified as having potential exposure to asbestos through work with or around Lamons gasket products:

Pipefitters and Pipe Trades Workers were primary users of flanged gaskets in industrial piping systems. Installing new gaskets and removing old ones from flanged connections — a routine maintenance task in any refinery or chemical plant — could disturb asbestos filler material and release fibers into the breathing zone.

Boilermakers worked on pressure vessels, heat exchangers, and boiler systems where spiral-wound and compressed sheet gaskets were standard sealing components. Plaintiffs alleged that boilermakers encountered Lamons products during both new construction and ongoing maintenance turnarounds.

Millwrights and Maintenance Mechanics performing general equipment maintenance at petrochemical facilities frequently handled gasket removal and replacement as part of broader repair work. Court filings document that such workers were present in environments where Lamons and other brand-name gaskets were routinely disturbed.

Insulators and Insulation Workers, while not directly handling gaskets, often worked in close proximity to pipefitters and boilermakers during industrial construction and maintenance, potentially encountering airborne fibers released by nearby gasket work.

Refinery and Chemical Plant Operators who performed or supervised maintenance work in their assigned process units may have been present during gasket removal and installation activities without the benefit of respiratory protection.

The Gulf Coast refining corridor — spanning coastal Texas and Louisiana — represents the densest geographic concentration of documented Lamons product use, based on the company’s Houston headquarters and established regional distribution. However, asbestos litigation records reflect claims by workers in facilities across multiple states and industrial sectors, reflecting the broader national distribution of Lamons products during the covered period.

Asbestos-related diseases associated with occupational gasket exposure — including mesothelioma, asbestosis, lung cancer, and pleural disease — typically have latency periods of 20 to 50 years between initial exposure and clinical diagnosis, meaning workers exposed to Lamons products during the 1950s through 1980s may be receiving diagnoses today.

Lamons Gasket Company is classified as a Tier 2 entity for purposes of asbestos litigation reference on this site. The company has been named as a defendant in asbestos personal injury litigation. According to asbestos litigation records, plaintiffs alleged that Lamons manufactured and distributed asbestos-containing gaskets that caused or contributed to occupational asbestos exposure and related disease. However, Lamons Gasket Company has not established an asbestos bankruptcy trust fund, meaning there is no dedicated trust through which claims can be submitted independently of litigation.

Individuals seeking compensation for asbestos-related disease connected to Lamons products would pursue claims through the civil court system rather than through a trust fund claims process. Legal options may also include claims against other defendants whose products were present in the same work environments — including manufacturers of other gasket brands, pipe insulation manufacturers, and facility owners — some of whom may have established asbestos trust funds.

Summary: What This Means for Workers and Families

If you or a family member worked as a pipefitter, boilermaker, millwright, or in another trades capacity at a Gulf Coast refinery, petrochemical plant, or chemical facility between approximately 1950 and 1986, and you have been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related condition, Lamons Gasket Company products may be relevant to your exposure history.

Because Lamons has not established a bankruptcy trust fund, compensation claims involving Lamons products are pursued through civil litigation rather than a trust submission process. Attorneys experienced in asbestos claims can evaluate whether Lamons and other product defendants are appropriate parties based on the specific facilities, job tasks, and time periods involved in your work history. Many workers exposed to Lamons products also have valid claims against trust funds established by other defendants whose products were present in the same environments.

Documentation of your work history — including employers, facility names, job titles, and the specific tasks you performed — is valuable in building an exposure history that identifies all relevant product defendants.
