A.W. Chesterton Co.: Asbestos History, Products & Litigation

History of A.W. Chesterton Co. and Its Asbestos Products

A.W. Chesterton Co. was founded in 1884 by Arthur W. Chesterton in the greater Boston area of Massachusetts. What began as a distributor of industrial maintenance supplies grew over the following century into a globally recognized manufacturer of sealing products, lubricants, and fluid handling equipment. For most of the twentieth century the company operated manufacturing and distribution operations from facilities in Stoneham and Woburn, Massachusetts, towns in the industrial belt north of Boston that were home to numerous manufacturing enterprises during the region's industrial peak.

Chesterton's reputation was built on the quality of its sealing products for demanding industrial applications. The company targeted the same core customer base as its principal competitors John Crane and Garlock: refineries, chemical plants, power generating stations, paper mills, and shipyards. These customers demanded sealing products that could withstand elevated temperatures, aggressive chemicals, and the mechanical wear generated by rotating shafts and reciprocating equipment.

For most of the period from the 1930s through the 1980s, meeting those performance demands meant incorporating asbestos into the product formulations. Chrysotile asbestos braided into compression packing produced a material that was heat stable, chemically resistant, conformable to shaft surfaces, and capable of maintaining a seal under the pressures encountered in industrial pump and valve applications. Asbestos fiber in sheet gasket material provided similar benefits for flanged connections carrying hot, pressurized process fluids.

Chesterton marketed its asbestos packing under a variety of style numbers and trade designations, and the products were available from industrial supply houses and Chesterton distributors throughout the United States. The national distribution reach of Chesterton sealing products means that exposure claimants may have encountered them not just in New England industrial facilities but across refineries, chemical plants, and paper mills throughout the country.

As awareness of asbestos health hazards grew through the 1970s and into the 1980s, Chesterton — like other packing manufacturers — developed non-asbestos alternatives and phased asbestos out of its product lines. However, the decades of prior sales meant that asbestos-containing Chesterton products remained in service in many industrial plants for years after their manufacture ceased, as maintenance crews used up existing inventory or worked on equipment where earlier Chesterton packing had been installed.

Unlike several of its direct competitors in the gasket and packing segment, A.W. Chesterton has continued to operate as a privately held company without seeking bankruptcy protection from its asbestos liabilities. This means that all claims against Chesterton must be pursued through direct civil litigation rather than through a bankruptcy trust claim process.

Chesterton Asbestos Products and Worker Exposure

The specific product categories manufactured by A.W. Chesterton that have been most frequently associated with asbestos exposure in litigation share a common characteristic: they were all products that workers handled directly and repeatedly as part of their routine job duties, and the process of installing, removing, or cutting these products released asbestos fibers into the air.

Compression Packing

Chesterton braided compression packing was a staple product for industrial pump and valve maintenance throughout the mid-twentieth century. The packing was manufactured in a range of cross-sectional sizes to fit the stuffing boxes of different pump models, and was sold in spool form from which maintenance workers cut individual packing rings sized to fit the specific equipment being serviced. The cutting process — whether with a knife, diagonal cutters, or a miter box — released asbestos fibers from the severed ends and surfaces of the braided material.

Equally significant was the removal of worn packing from pump stuffing boxes. Over time, compression packing compresses, hardens, and becomes difficult to remove intact. Maintenance mechanics used hook-shaped picks and packing pullers to bore out the degraded packing material, a process that disturbed and fragmented the asbestos-containing material and generated substantial fiber release. Workers performed this task in the confined area immediately around the pump, often in poorly ventilated equipment rooms or process areas where fiber concentrations could accumulate.

Rope Packing

Chesterton asbestos rope packing was used to seal boiler doors, furnace openings, kiln doors, and other high-temperature closure applications where the rope could be compressed into a groove or channel to form a heat-resistant seal. The rope was typically cut to length and pressed or woven into the sealing groove, and replacement involved removing degraded rope material that had been exposed to high temperatures and had become brittle and friable. Boilermakers and industrial furnace maintenance workers were the primary users of Chesterton rope packing.

Sheet Gasket Material

Chesterton compressed asbestos fiber sheet gasket material was used wherever flanged pipe connections, heat exchanger covers, or pressure vessel nozzles required a conformable, chemically resistant seal. As with comparable products from Garlock and John Crane, the act of cutting Chesterton sheet gaskets to match specific flange bolt patterns and inside diameters released asbestos dust. Pipefitters who fabricated gaskets from sheet stock as part of routine maintenance work encountered this exposure with every gasket they cut.

Valve Stem Packing

Gate valves, globe valves, and other industrial valve types use packing material in the stuffing box or gland around the valve stem to prevent process fluid leakage along the stem as the valve is operated. Chesterton braided and die-formed packing was widely used in valve maintenance. Mechanics who repacked valve glands — at installed valve locations or on benches in maintenance shops — handled Chesterton packing directly in the same cutting and installation tasks that generated exposure from pump packing work.

The Woburn, Massachusetts Manufacturing Operations

The Woburn, Massachusetts area where A.W. Chesterton maintained significant manufacturing and distribution operations has its own distinctive place in the history of industrial activity north of Boston. Woburn became nationally known through a separate contamination case involving trichloroethylene pollution by other industrial operators in the area — that case became the subject of Jonathan Harr's book A Civil Action. While that contamination matter involved different companies and different chemicals, it reflects the concentration of manufacturing enterprises that operated in the Woburn corridor through much of the twentieth century.

Chesterton's presence in Stoneham and Woburn placed it at the center of a dense industrial ecosystem that included suppliers, customers, and a skilled manufacturing workforce familiar with the demands of industrial sealing applications. The Massachusetts manufacturing base gave Chesterton strong relationships with New England industrial employers — particularly the electric utilities, paper mills, textile mills, and defense-related manufacturers that anchored the regional industrial economy through the mid-twentieth century.

Workers at the Chesterton manufacturing facilities themselves were also potentially exposed to asbestos in the course of production operations, as raw asbestos fiber was processed and incorporated into packing and gasket products. The mixing, braiding, and finishing of asbestos packing materials at the plant generated occupational fiber exposures that were consistent with the risk profiles documented in other textile-type asbestos manufacturing operations. However, the overwhelming majority of asbestos exposure litigation against Chesterton involves downstream industrial workers who used the company's products in the field, rather than plant workers who manufactured them.

Today, A.W. Chesterton Co. operates from its headquarters in Groveland, Massachusetts, and continues as an active manufacturer of sealing products, fluid handling equipment, and maintenance chemicals. The company's non-asbestos product lines remain in active commercial use globally. Its asbestos legacy is managed through the civil litigation system, where cases from across the country are actively contested in multiple jurisdictions.

A.W. Chesterton Asbestos Litigation: No Trust Fund

A.W. Chesterton Co. is a privately held company that has not sought bankruptcy protection from its asbestos liabilities. This distinguishes it from many well-known asbestos defendants — including Garlock, Armstrong World Industries, W.R. Grace, and dozens of others — that resolved their asbestos liabilities through Chapter 11 bankruptcy proceedings and established trust funds to compensate future claimants at discounted payment percentages.

Because Chesterton remains a solvent, operating company, claimants seeking compensation for asbestos diseases caused by Chesterton products must file a lawsuit and pursue the claim through the civil court system. This process typically begins with a complaint filed in the jurisdiction where the claimant was exposed to Chesterton products or where the claimant resides, and proceeds through the standard stages of civil asbestos litigation: discovery, expert witness depositions, and ultimately trial or settlement.

The absence of a trust fund has both advantages and disadvantages for claimants. On the positive side, there is no cap on potential recovery imposed by trust distribution procedures, punitive damages may be available if the evidence supports a finding of reckless conduct, and the full evidentiary record of the claimant's exposure and the company's conduct can be presented to a jury. On the negative side, litigation takes longer than trust fund claims, requires more extensive factual investigation, and carries the inherent uncertainty of trial outcomes.

Most asbestos attorneys who represent mesothelioma victims pursue claims against multiple defendants simultaneously — filing trust fund claims against bankrupt defendants at the same time as civil lawsuits against solvent defendants like Chesterton. This strategy maximizes total recovery by accessing all available compensation sources without requiring the claimant to choose between the trust fund and litigation routes.

Chesterton actively defends its asbestos cases, retaining experienced asbestos defense counsel and contesting both the adequacy of exposure proof and the causation evidence in each case. Courts have seen extensive evidence about the Chesterton product line in the course of this litigation, and experienced plaintiff attorneys who specialize in sealing products cases will be familiar with the relevant evidence and arguments on both sides.
