John Crane Inc. is a manufacturer of industrial sealing products, including mechanical seals, gaskets, and packing materials, historically used in pumps, valves, and rotating equipment across maritime, refining, power generation, and chemical processing industries. From roughly the 1950s through the mid-1980s, many of its packing and gasket products contained asbestos fibers, and the company has been a frequent and prominent defendant in asbestos personal injury and mesothelioma litigation in the United States.

Origin

The company traces its roots to a packing and gasket business founded by John Crane in Chicago in 1917. It later became part of the British industrial group Smiths Group plc, and the asbestos-containing era of its product line coincided with the mid-20th century industrial expansion in fluid sealing technology.

Significance in Asbestos Context

For patients with mesothelioma or other asbestos diseases, John Crane is significant because its asbestos-containing packing (often braided rope packing used to seal pump shafts) and sheet gaskets were widely installed and replaced in industrial settings, shipyards, Navy vessels, refineries, and powerhouses. Workers such as machinists, pipefitters, boiler tenders, Navy enginemen, millwrights, and maintenance mechanics were commonly exposed when cutting, installing, removing, or replacing these products, which released respirable fibers. John Crane has aggressively contested causation in litigation, particularly arguing that its encapsulated chrysotile products released few fibers, making expert testimony on fiber release and dose especially important in cases naming the company.

Notes

  • If you or a family member worked with pumps, valves, or rotating machinery, try to recall and document brand names of packing and gaskets. John Crane products were often labeled "Crane" or carried product codes like 'Style 187-I' that experts can identify.
  • Preserve any old work records, union books, purchase orders, maintenance logs, or co-worker contacts that can confirm use of John Crane sealing products at specific worksites and time periods.
  • Ask your attorney about John Crane's defense that chrysotile in its products did not release harmful fiber levels; cases typically require industrial hygiene or exposure-reconstruction experts to rebut this.
  • Navy veterans should specifically note ship names, hull numbers, and engine room or auxiliary machinery assignments, since John Crane products were common in shipboard pump and valve packing.
