Worthington Pump with Asbestos Gaskets

Product Description

Worthington pumps were heavy-duty industrial pumps manufactured and distributed across a wide range of commercial, industrial, and petrochemical applications from 1942 through 1982. During this four-decade production window, these pumps were assembled and supplied with internal gaskets and sealing components that contained asbestos as a primary binding and heat-resistant material. Halliburton, through its various subsidiaries and business operations, was involved in the manufacture, distribution, or supply of Worthington pump assemblies and associated components during this period.

Worthington pumps were engineered to handle extreme operating conditions, including high-pressure fluid transfer, high-temperature process streams, and chemically aggressive environments. These demands made asbestos-containing gaskets an industry-standard choice for the era. Asbestos gaskets were prized for their ability to maintain seals under thermal cycling, pressure fluctuations, and chemical exposure that would rapidly degrade alternative materials available at the time.

These pumps were installed across a broad spectrum of industrial environments, including oil refineries, chemical processing plants, power generation facilities, manufacturing plants, shipyards, and heavy industrial complexes. Because of their widespread deployment, Worthington pumps with asbestos-containing gaskets represent a documented source of occupational asbestos exposure for industrial workers who installed, operated, inspected, repaired, and maintained this equipment across several decades.

Asbestos Content

The gaskets associated with Worthington pumps during the 1942–1982 production period contained chrysotile asbestos, the most commercially prevalent form of asbestos used in industrial sealing products throughout the twentieth century. Chrysotile, commonly referred to as white asbestos, belongs to the serpentine mineral family and was widely incorporated into compressed asbestos sheet gaskets, spiral-wound gaskets, and ring gaskets used in pump flanges, valve connections, and internal sealing surfaces.

Chrysotile asbestos fibers were processed into gasket sheet material by combining the mineral with binders, fillers, and rubber compounds under compression. The resulting sheets could be cut to precise dimensions and installed as flat gaskets in pump flanges and mating surfaces throughout the assembly. In some configurations, chrysotile fibers were also incorporated into packing material used in pump stuffing boxes and mechanical seal areas.

Regulatory recognition of chrysotile asbestos as a human carcinogen and serious occupational health hazard developed progressively through the latter half of the twentieth century. The Occupational Safety and Health Administration (OSHA) has established permissible exposure limits for asbestos fiber concentrations in workplace air, and the Environmental Protection Agency (EPA) regulations under the Asbestos Hazard Emergency Response Act (AHERA) further codified the known dangers of asbestos-containing materials. All commercial forms of asbestos, including chrysotile, are classified as known human carcinogens by major regulatory and scientific bodies, and exposure has been causally linked to mesothelioma, asbestosis, lung cancer, and other serious diseases.

How Workers Were Exposed

Industrial workers who worked with or around Worthington pumps during the 1942–1982 period faced potential asbestos exposure through multiple routine and maintenance-related work tasks. The gaskets installed at the time of manufacture were not the sole source of exposure; rather, exposure occurred repeatedly over the operational lifespan of each pump as workers performed inspections, replacements, and repairs.

The primary exposure pathway involved the disturbance of installed asbestos-containing gaskets during routine maintenance activities. When workers broke flange connections to inspect internal pump components, remove worn gaskets, or address leaks, the act of separating bonded flange faces released asbestos-containing debris and dust. Gaskets that had been subjected to heat and pressure over extended service periods frequently bonded to metal flange surfaces and required mechanical removal using scrapers, wire brushes, grinders, or abrasive pads. These removal methods generated respirable asbestos fiber concentrations recognized by industrial hygiene standards as potentially hazardous.

Similarly, workers who cut replacement gaskets from asbestos sheet material using knives, shears, or hole saws generated airborne asbestos dust during the cutting process. In many industrial settings, replacement gaskets were fabricated on-site from bulk asbestos sheet stock, meaning that workers performing this task could be exposed not only during installation but also during gasket preparation.

Workers replacing or repacking pump stuffing boxes were also at risk when the packing material contained chrysotile asbestos. Removing old packing, cleaning the stuffing box cavity, and installing new packing material were all tasks that could disturb asbestos-containing materials and release fibers into the breathing zone.

Beyond the mechanics directly performing gasket work, bystander industrial workers in the immediate vicinity of these activities could also inhale airborne fibers without directly touching the pump components. In enclosed industrial environments with limited ventilation, fiber concentrations could persist and affect workers in adjacent areas. Supervisors, helpers, pipefitters, millwrights, and other trades present in the same workspace during maintenance operations were potentially exposed through this indirect pathway.

The latency period for asbestos-related diseases, which can range from ten to fifty years following initial exposure, means that workers exposed during the 1942–1982 production period may be receiving diagnoses today.

Worthington pumps with asbestos-containing gaskets are classified as a Tier 2 product for legal purposes, meaning no dedicated asbestos bankruptcy trust fund has been established specifically to compensate claimants for exposure to this product. Compensation for individuals harmed by exposure to Worthington pumps is pursued through civil litigation in state and federal courts.

Litigation records document that plaintiffs have filed claims against Halliburton and related corporate entities in connection with asbestos-containing components supplied with or associated with Worthington pump assemblies. Plaintiffs alleged that Halliburton and its subsidiaries knew or should have known of the hazards associated with chrysotile asbestos in pump gaskets and failed to adequately warn workers or take reasonable steps to reduce foreseeable exposure risks.

Plaintiffs alleged that injuries including mesothelioma, asbestosis, lung cancer, and related conditions resulted from occupational exposure to asbestos fibers released during the handling, installation, and removal of gaskets used in Worthington pump assemblies. Litigation records document claims brought by industrial workers from refinery, chemical plant, power generation, and manufacturing environments where these pumps were in service.

Individuals diagnosed with mesothelioma or other asbestos-related diseases who have a documented work history involving Worthington pumps or related Halliburton-supplied equipment should consult with an attorney who specializes in asbestos litigation. Legal counsel experienced in this field can evaluate work history records, medical documentation, product identification evidence, and co-defendant exposure pathways to determine the full scope of available legal remedies.

Because exposure to Worthington pumps frequently occurred alongside exposure to other asbestos-containing products in the same industrial environments, attorneys may also evaluate eligibility for claims against asbestos bankruptcy trusts established by other manufacturers of gaskets, packing, insulation, and related products that were present in the same workplaces.

Statutes of limitations vary by state and typically begin running from the date of diagnosis rather than the date of exposure. Prompt consultation with qualified legal counsel is recommended to preserve all available legal options.
