A.W. Chesterton Company was founded in 1884 in Boston, manufacturing and selling engineering and steamboat supplies. Over time, the company expanded its offering and supplied goods for a variety of industries around the world. However, as they grew, the company began incorporating asbestos into their materials until the 1980s.

A.W. Chesterton acquired many companies over its years of expansion, allowing it to serve more industries and extend its reach to countries like Canada and Mexico by the 1940s. During these crucial years of expansion and adding products like gaskets, pumps, lubricants and more, the company used asbestos to add durability and heat-resistance. Because the company had over 1,000 employees and distributed its products globally, hundreds of thousands of workers and consumers risked asbestos exposure. As a result, A.W. Chesterton Co. continues to be named in asbestos lawsuits today.

Arthur “A.W.” Chesterton founded his company in 1884 with the goal of supplying his customers quickly with the products they needed. The company initially focused on goods within the engineering and steamboat product industry. Within the next ten years, A.W. expanded into manufacturing and distributing pump packing and gasketing within the sealant industry, which would later prove to be their most profitable product line.

By 1905, the company achieved national distribution as they acquired Ingall’s Boiler Cleaners and Scrapers. Within the next several decades, A.W. Chesterton Co. continued to increase sales, with a larger focus on their heat-resistant gasket and pump line of products. By the 1920s, catalogs show the company began relying on asbestos as a cost-effective additive to their products to boost durability and fire-resistance.

The 1960s through the 1990s proved to be the largest period of growth and expansion for the company. A.W. introduced production and distribution of numerous new products, including lubricants, cleaners, sealants and split seals. Through the early 1980s, the majority of these products contained varying amounts of asbestos. Because of their steady growth and expansion into new markets overseas, these products put thousands at risk of dangerous exposure.

Asbestos Litigation Against A.W. Chesterton Company

For more than 60 years, A.W. Chesterton utilized toxic asbestos fibers in a variety of their popular products that were manufactured and distributed all over the world. Thousands of workers and consumers of these products faced exposure and began to develop serious asbestos diseases like lung cancer and mesothelioma.

Court documents show A.W. Chesterton Company was first named as a defendant in a lawsuit in January 1980. By the time of trial, the company was facing more than 300,000 similar claims after employees and other workers were diagnosed with mesothelioma or other health conditions. Since then, the company has continued to deal with thousands of asbestos claims against it for wrongful exposure.

One such case was filed by Richard Keeney, a Navy veteran who worked with a variety of asbestos products during his tenure, including those from A.W. Chesterton. He claimed he was never provided any safety information about asbestos or protective gear, and wasn’t fully aware of the dangers. Richard developed mesothelioma due to his exposure aboard naval vessels. As a result, he was awarded more than $5.5 million for medical expenses, loss of income and the pain and suffering caused by his diagnosis.

A.W. Chesterton continues to handle similar claims today.
