Product Description

Pittsburgh Corning Corporation (a 50/50 joint venture formed 1937 by PPG Industries and Corning Glass Works; today Owens Corning subsidiary after Corning’s 2016 stake sale) allegedly manufactured through 1962-1972 the Unibestos brand of amosite (brown asbestos) pipe covering and block insulation — one of the most heavily-litigated U.S. amosite asbestos products in U.S. workplace asbestos personal-injury litigation.

Amosite asbestos (brown asbestos, sourced principally from South African mines) is one of the most-hazardous amphibole asbestos fibers because of its long, needle-like fiber morphology that produces particularly aggressive mesothelioma cancers. Unibestos amosite pipe covering and block insulation was widely specified in U.S. refineries, marine and shipbuilding operations, power plants, and industrial construction through the 1962-1972 production window.

Pittsburgh Corning is one of the most heavily-litigated U.S. asbestos defendants; the Pittsburgh Corning Corporation Asbestos PI Trust was established under Pittsburgh Corning’s 2000 Chapter 11 to handle asbestos personal-injury liability.

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Pittsburgh Corning Unibestos pipe covering and block insulation contained amosite asbestos through the documented production era and that insulators, pipefitters, marine machinists, and refinery operators who cut, fit, installed, and removed Unibestos products released substantial respirable amosite asbestos fibers.

Pittsburgh Corning Corporation has been named as a Manufacturer Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation. Pittsburgh Corning asbestos liability is channeled through the Pittsburgh Corning Asbestos PI Trust.

If You Worked With Pittsburgh Corning Unibestos

If you cut, installed, repaired, or removed Pittsburgh Corning Unibestos amosite pipe covering or block insulation during the 1962-1972 production era or during subsequent decades of tear-out and replacement work — and have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related illness — you may have legal rights, including potentially a trust claim against the Pittsburgh Corning Asbestos PI Trust.
