General Gasket Corporation is a U.S. specialty gasket manufacturer that allegedly supplied asbestos-bearing gaskets and sealing products to U.S. transformer manufacturers, electrical equipment OEMs, and broader industrial customers during the asbestos era. General Gasket Corporation is named as a defendant in publicly filed U.S. asbestos litigation including the Duke v. CBS Corporation et al. case (Cause No. 1822-CC00339, City of St. Louis MO) regarding asbestos-bearing transformer gaskets and sealing products allegedly handled by U.S. transformer service-center workers, industrial maintenance crews, and utility substation electricians. Per publicly filed allegations, General Gasket Corporation asbestos gaskets allegedly served as flange seals, bushing penetrations, tap-changer interfaces, and pressure-vessel sealing components in U.S. power transformers, valves, pumps, and pressure equipment manufactured during the 1950s-1980s asbestos era.

  • Transformer dismantling and rebuild at service centers — extracting aged asbestos components from field-aged General Gasket Corporation transformers (highest documented exposure category)
  • Coil-winding operations — fitting asbestos transformer paper and phenolic spacers during winding assembly
  • Machining and trimming — drilling, sawing, and finishing operations on cured phenolic and asbestos-bearing laminate
  • Field maintenance and substation service — utility substation electricians, lineworkers, and industrial electricians handling General Gasket Corporation transformers during in-service repair
  • Reconditioning operations — heat-baking, vacuum drying, and oil refilling of disassembled transformer units saturated with asbestos fiber
