Product Description

Bell & Gossett (Morton Grove, IL; later ITT Bell & Gossett) allegedly manufactured a full line of shell-and-tube heat exchangers for HVAC, hydronic-system, and industrial process service throughout the mid-twentieth century. Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that the flange gaskets between the exchanger shell, channel cover, floating-head cover, and tube-sheet were manufactured from compressed asbestos fiber (CAF) sheet material or asbestos-cored spiral-wound rings, and that Bell & Gossett supplied both original-equipment gasket sets and aftermarket replacement gaskets in gasket kits shipped with retubing bundles.

This product page covers the shell-and-tube exchanger gaskets specifically, distinct from Bell & Gossett pump packing and B&G circulator seals (covered on sibling pages).

Workers Exposed

Plaintiffs allegedly identified the following trades as exposed during Bell & Gossett heat exchanger service:

  • Pipefitters and steamfitters pulling floating-head covers and cutting replacement gasket blanks to size.
  • HVAC mechanics servicing hydronic-system shell-and-tube heat exchangers in commercial buildings.
  • Industrial millwrights performing annual tube-bundle pulls, retubing, and head re-gasketing at chemical plants and refineries.
  • Boilermakers replacing tube-sheet gaskets after hydrostatic testing.

Alleged exposure mechanisms included chiseling cured gasket residue from raised-face flanges, wire-brushing the tube-sheet groove, and cutting gasket stock on the shop bench.
