Lamons Spiral-Wound Metallic Gaskets with Asbestos Filler

Product Description

Lamons Gasket Company, headquartered in Houston, Texas, manufactured spiral-wound metallic gaskets from the mid-twentieth century through the mid-1980s. These gaskets were engineered for demanding industrial sealing applications — particularly in high-pressure, high-temperature environments such as oil refineries, chemical processing plants, power generation facilities, and petrochemical operations. Spiral-wound gaskets represented a specialized category of industrial sealing product, distinct from flat sheet gaskets, and were valued for their ability to maintain reliable seals under the extreme mechanical and thermal stresses common to heavy industrial piping systems.

The construction of a spiral-wound gasket involves alternating layers of formed metallic strip — typically stainless steel or carbon steel — and a soft filler material, wound in a spiral configuration and compressed between pipe flanges. The filler material provides the compressible, conforming element that achieves the actual seal. For much of the period from the 1950s through 1986, Lamons and other gasket manufacturers incorporated asbestos-based materials as the filler component in these products, given asbestos fiber’s well-established resistance to heat, chemical degradation, and mechanical compression. Lamons spiral-wound gaskets with asbestos filler were widely distributed throughout American industrial infrastructure during this era, appearing in refineries, paper mills, steel plants, marine installations, and commercial buildings across the country.

Asbestos Content

The filler material in Lamons spiral-wound metallic gaskets produced during the relevant period consisted of asbestos-based sheet or yarn, most commonly incorporating chrysotile (white asbestos) or, in some formulations, amphibole fiber varieties. The asbestos filler was positioned between the metal windings to provide the compressible sealing interface. Documentation in litigation records confirms that Lamons manufactured these gaskets with asbestos filler material through at least 1986, consistent with the broader industrial gasket industry’s transition away from asbestos-containing materials following increasing regulatory pressure from the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) during the late 1970s and 1980s.

The asbestos content in spiral-wound gaskets was integral to the product’s design rather than incidental. Filler materials were selected specifically because asbestos fibers provided thermal stability, chemical resistance, and compressibility that few alternative materials could match for the pressure and temperature ranges these gaskets were intended to serve. This design integration meant that the asbestos was present throughout the service life of each gasket — from installation to removal — and was not limited to the manufacturing process alone.

How Workers Were Exposed

Litigation records document that workers in a broad range of industrial trades encountered Lamons spiral-wound metallic gaskets with asbestos filler during installation, maintenance, and removal operations. The industries most heavily represented in exposure documentation include petroleum refining, chemical manufacturing, power generation, maritime operations, and general industrial construction and maintenance.

Exposure pathways were documented across several distinct work activities:

Installation. When installing spiral-wound gaskets on pipe flanges, workers handled the gaskets directly. Plaintiffs alleged that cutting, trimming, or fitting gaskets to non-standard configurations released asbestos fibers into the breathing zone of the installer and nearby workers.

Removal and replacement. Maintenance operations requiring disassembly of flanged pipe connections involved breaking the compressed seal of previously installed gaskets. Plaintiffs alleged that this process — which often required scraping, wire-brushing, or grinding residual filler material from flange faces — generated significant concentrations of airborne asbestos fibers. Gasket removal was a routine maintenance task in refineries and chemical plants, performed on scheduled turnarounds as well as unplanned shutdowns, meaning that workers in these environments could be exposed repeatedly over the course of careers spanning decades.

Proximity exposures. Litigation records document that workers who did not directly handle gaskets were nonetheless potentially exposed when gasket work was performed in shared workspaces, enclosed equipment rooms, or confined spaces aboard ships and in industrial facilities. Pipefitters, boilermakers, millwrights, and general maintenance workers were among the trades documented in litigation as having sustained exposure in this manner.

Lack of warnings. Plaintiffs alleged that Lamons Gasket Company failed to provide adequate warnings to workers about the asbestos content of its spiral-wound gaskets or the health hazards associated with asbestos fiber inhalation, even as scientific and medical understanding of asbestos-related disease was becoming well established in the occupational health literature during the 1960s and 1970s. Litigation records further document allegations that the absence of labeling or safety instructions left workers and their employers without information necessary to implement protective measures.

Diseases documented in litigation involving Lamons spiral-wound gaskets with asbestos filler include mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease. The latency period for asbestos-related malignancies — often twenty to fifty years between initial exposure and clinical diagnosis — means that individuals exposed to these products during their working years in the 1950s through the 1980s may only now be receiving diagnoses.

Lamons spiral-wound metallic gaskets with asbestos filler are classified as a Tier 2 litigated product. There is no dedicated Lamons Gasket trust fund established under Section 524(g) of the U.S. Bankruptcy Code currently documented for this manufacturer in publicly available trust fund records. Individuals diagnosed with asbestos-related disease following exposure to these products have pursued remedies through the civil tort system.

Civil Litigation

Litigation records document that plaintiffs diagnosed with mesothelioma, lung cancer, and asbestosis have brought claims against Lamons Gasket Company and, in many cases, against multiple co-defendants in the same action — including other gasket manufacturers, raw asbestos suppliers, industrial facility owners, and contractors. Cases have been filed in jurisdictions throughout the United States, with notable concentrations in Texas and Louisiana courts given the density of refinery and petrochemical industry employment in those states.

Plaintiffs in these cases have alleged product liability under theories of negligence, strict liability for defective design and failure to warn, and, in some jurisdictions, fraud-based claims related to industry knowledge of asbestos hazards. Litigation records reflect settlements and verdicts in favor of plaintiffs in cases involving Lamons products, though specific case outcomes vary by jurisdiction, diagnosis, and documented exposure history.

Steps for Affected Individuals

Individuals who worked in industrial environments where Lamons spiral-wound gaskets were installed, maintained, or removed, and who have received a diagnosis of mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease, should consult with an attorney experienced in asbestos litigation. Documentation of employment history, job site records, co-worker testimony, and product identification evidence is important to building a viable legal claim. Because statutes of limitations vary by state and generally begin running from the date of diagnosis or discovery of the asbestos-related condition, prompt consultation with qualified legal counsel is advisable.
