Lamons Flexitallic-Equivalent Spiral Wound Gaskets

Product Description

Lamons Gasket Company, headquartered in Houston, Texas, was one of the principal American manufacturers of industrial sealing products throughout the mid-twentieth century and beyond. Among its product lines, Lamons produced spiral wound gaskets designed to perform under the demanding conditions found in refineries, chemical processing plants, power generation facilities, and heavy industrial operations. These gaskets were engineered to function as equivalents to — and direct competitors of — the widely recognized Flexitallic spiral wound gasket, which had established the dominant standard for high-pressure, high-temperature sealing applications in American industry.

Spiral wound gaskets of this type were constructed using alternating layers of thin metal strip and soft filler material, wound together in a tight coil to create a compressible sealing element capable of withstanding extreme pressure and temperature cycling. The metal component was typically a stainless steel or carbon steel winding, while the filler material provided the actual sealing function by conforming to flange irregularities and maintaining a pressure-tight barrier. In the industrial era when these gaskets were most widely deployed, asbestos-containing materials served as the preferred filler for high-performance spiral wound gaskets, including those manufactured by Lamons.

These gaskets were installed in flanged pipe connections, heat exchangers, pressure vessels, valves, and a wide range of process equipment throughout industrial facilities across the United States. Their broad application in critical sealing locations meant they were handled by maintenance workers, pipefitters, insulators, and general industrial laborers across countless facilities over several decades.


Asbestos Content

The filler material used in spiral wound gaskets manufactured during the primary period of Lamons production consisted of compressed asbestos fiber, typically in the form of flexible asbestos sheet or yarn integrated between the metal windings. Asbestos was selected for this application because of its well-documented resistance to heat, chemical exposure, and pressure — properties that made it technically well-suited to the refinery and petrochemical environments where these gaskets were most commonly installed.

Chrysotile asbestos was the variety most commonly incorporated into gasket filler materials of this type, though some formulations may have included amphibole fiber types depending on the specific application requirements of the end user. The asbestos filler material was bonded within the spiral winding, giving the finished gasket a distinctive appearance that did not obviously signal the presence of fibrous asbestos to workers handling or cutting the product.

Because the asbestos was integrated into the winding rather than applied as a loose surface coating, the material was considered relatively stable under undisturbed conditions. However, the normal processes of installation, removal, and maintenance — particularly cutting, trimming, or wire-brushing gasket surfaces — were capable of releasing asbestos fibers into the surrounding work environment.


How Workers Were Exposed

Industrial workers in refineries, chemical plants, paper mills, power stations, and marine facilities encountered Lamons spiral wound gaskets and equivalent products throughout routine maintenance and construction activities. Exposure pathways were documented in multiple workplace contexts, and litigation records document the varied circumstances under which workers alleged contact with asbestos-containing gasket materials.

Installation and Removal: Workers installing spiral wound gaskets in flanged pipe systems were required to handle the gaskets directly, sometimes trimming them to fit or inspecting the seating surface. Removing spent gaskets from flanged connections — a process that frequently required scraping, wire brushing, or grinding the flange face to remove adhered gasket residue — was identified as a particularly significant source of fiber release.

Cutting and Trimming: When spiral wound gaskets did not precisely match a flange dimension, workers would cut them to size using handsaws, tin snips, or grinding tools. These cutting operations were capable of releasing asbestos fibers from the filler material in concentrations that could remain airborne for extended periods.

Proximity Exposure: Plaintiffs alleged in numerous civil actions that workers did not need to directly handle gasket materials to sustain exposure. Bystander workers — those in the vicinity of gasket installation or removal operations without performing the work themselves — were also alleged to have inhaled asbestos fibers released by nearby colleagues.

Accumulated Exposure in Industrial Settings: In refineries and petrochemical facilities, where thousands of flanged connections might be maintained over the course of a single facility turnaround or scheduled outage, workers were potentially exposed to asbestos fibers from multiple gasket-containing systems simultaneously. Litigation records document that industrial workers employed at such facilities over extended careers accumulated repeated exposures through the ordinary performance of their assigned duties.

Trades identified in litigation as having encountered Lamons and Lamons-equivalent spiral wound gaskets include pipefitters, boilermakers, millwrights, refinery operators, maintenance mechanics, and general industrial laborers. Workers in Gulf Coast refinery and petrochemical complexes — where Lamons Gasket Company had a particularly strong market presence — were disproportionately represented in litigation records.


Lamons Gasket Company has not established a dedicated asbestos bankruptcy trust fund, as the company did not undergo the Chapter 11 reorganization process that gave rise to trust fund compensation systems for many other asbestos product manufacturers. Accordingly, claims involving Lamons spiral wound gaskets fall within the Tier 2 litigation framework rather than the trust fund claim process.

Civil Litigation: Plaintiffs alleging asbestos-related disease arising from exposure to Lamons spiral wound gaskets have pursued claims through civil tort litigation in state and federal courts. Litigation records document that such claims have been filed by workers diagnosed with mesothelioma, asbestos-related lung cancer, and asbestosis, as well as by surviving family members bringing wrongful death actions.

Basis of Claims: Plaintiffs alleged that Lamons Gasket Company knew or should have known of the hazards associated with asbestos-containing products and failed to provide adequate warnings to workers who would foreseeably encounter those products in industrial settings. Claims have also alleged design defects and failure to transition to safer alternative filler materials once non-asbestos substitutes became technically viable.

Multi-Defendant Litigation: Because spiral wound gaskets were typically one of many asbestos-containing products present in industrial facilities, litigation involving Lamons gaskets has commonly proceeded alongside claims against other manufacturers of insulation, packing, refractory materials, and additional gasket products. The multi-defendant structure of such cases reflects the overlapping exposures characteristic of industrial worksites.

Consulting an Attorney: Workers diagnosed with mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease who handled or worked in proximity to spiral wound gaskets — including Lamons-manufactured products — in industrial settings should consult a qualified asbestos attorney. Legal counsel experienced in occupational asbestos litigation can evaluate the full exposure history, identify all potentially liable defendants, and advise on the most appropriate legal strategy given the diagnosed condition and applicable statutes of limitations.
