  • Boiler products: Johns-Manville, Eagle-Picher, Combustion Engineering, Babcock & Wilcox
  • Gaskets: Garlock Sealing Technologies, Flexitallic, John Crane, Chesterton

Many of these companies have established asbestos bankruptcy trusts. An attorney’s case investigation typically identifies which specific products were used at your worksite and which trusts apply to your claim.
