H.K. Porter Company Asbestos Trust

About the H.K. Porter Trust

H.K. Porter Company was a Pittsburgh, Pennsylvania-based industrial conglomerate that built a portfolio of manufacturing subsidiaries across multiple industries during the mid-twentieth century. Porter's asbestos-related operations were extensive and diverse, encompassing the manufacture of asbestos textiles, specialty insulation products, asbestos-containing gaskets and packing, and other industrial materials through various subsidiary companies. Because of Porter's diversified structure, its asbestos liability extended across many different industrial sectors and product categories — a breadth that ultimately contributed to the overwhelming claims volume that drove the company into bankruptcy.

Among H.K. Porter's most significant asbestos-related subsidiaries was Thermbestos, which manufactured asbestos textile products including woven cloth, braided rope, tape, yarn, and related materials for high-temperature industrial applications. Asbestos textiles were used throughout industrial facilities as fire blankets, furnace door seals, electrical insulation wrap, and pipe insulation jacketing. Workers who handled these products — both the textile mill workers who produced them and the industrial workers who installed and maintained them — were exposed to asbestos fibers released during manufacturing and fabrication operations.

Porter's operations also included gasket and packing manufacturing operations that supplied asbestos-containing sealing products to industrial and marine markets. Pipefitters, mechanics, and maintenance workers who cut and handled these gaskets were exposed to asbestos fibers during installation and removal. The company's reach across multiple asbestos product categories meant that workers at steel mills, power plants, chemical facilities, textile mills, and shipyards may all have encountered Porter products in the course of their work.

H.K. Porter Company filed for Chapter 11 bankruptcy protection in 1991, one of the earlier major asbestos-related bankruptcies. The proceedings were lengthy and complex, involving Porter's extensive subsidiary structure and the need to allocate liability across multiple product lines and corporate entities. The H.K. Porter Asbestos Trust was established in 1999, following eight years of bankruptcy proceedings. The trust's 3% payment percentage reflects the severe mismatch between available assets and the projected volume of claims from workers exposed across Porter's many operations. Despite this low percentage, the H.K. Porter claim is a component of the broader asbestos trust system that experienced workers can access as part of a multi-trust compensation strategy.

Trust Fund Details

Note: The 3% payment percentage is among the lowest in the asbestos trust system. However, the H.K. Porter claim is still worth filing as part of a comprehensive multi-trust strategy. Payment percentages may change. Consult an asbestos attorney for current information.

Who Is Eligible to File an H.K. Porter Trust Claim?

Eligibility for the H.K. Porter Trust requires demonstrating exposure to an asbestos-containing product manufactured by H.K. Porter Company or one of its subsidiaries, and a qualifying asbestos-related disease diagnosis. Given the breadth of Porter's operations, workers across many industries may be eligible:

• Asbestos textile mill workers at facilities where Thermbestos or other H.K. Porter subsidiary products were produced, including workers who wove, braided, and processed asbestos yarn, cloth, and rope
• Industrial insulation workers who installed and maintained asbestos textile products as high-temperature insulation jackets and fire barriers at industrial facilities
• Pipefitters and steamfitters who used H.K. Porter asbestos gaskets, packing, and valve stem seals in industrial piping systems
• Boilermakers who worked with H.K. Porter asbestos rope and textile seals on boiler door and access panel gaskets
• Steel mill workers at facilities where H.K. Porter asbestos textile products were used for furnace seals, protective barriers, and maintenance applications
• Power plant workers at generating stations using H.K. Porter asbestos cloth for turbine insulation and high-temperature sealing applications
• Shipyard workers who installed H.K. Porter asbestos textiles and gasket products on naval and commercial vessels
• Chemical plant and refinery workers who worked with H.K. Porter asbestos gaskets and specialty insulation products on process equipment
• Maintenance mechanics at any industrial facility that used H.K. Porter asbestos products in regular maintenance operations
• Secondary exposure claimants — family members exposed to asbestos fibers brought home on workers' clothing from H.K. Porter product exposure environments

H.K. Porter's asbestos products were most widely used from the 1940s through the early 1980s. Workers from this era who later developed mesothelioma, asbestosis, or other asbestos diseases remain eligible to file trust claims, subject to applicable state statutes of limitations.

How to File an H.K. Porter Trust Claim

The H.K. Porter Trust claim process is managed by Claims Management, Inc. (CMI), a major asbestos trust claims administrator. An asbestos attorney handles the process on contingency — no legal fees until you receive compensation.

1. Contact an experienced asbestos attorney. The H.K. Porter Trust has a low payment percentage, so it is most valuable as part of a comprehensive multi-trust filing strategy. Choose an attorney who can identify all applicable trusts from your complete work history — both Porter and others — and file all claims simultaneously.
2. Obtain your medical diagnosis documentation. The trust requires pathology reports, physician records, and other documentation confirming your mesothelioma or other qualifying asbestos-related disease diagnosis. Your attorney will review the specific medical requirements under the H.K. Porter TDP.
3. Build your H.K. Porter product exposure history. Your attorney will help you document that you worked with or were exposed to H.K. Porter asbestos products specifically. Relevant evidence includes employment records at facilities using Porter products, union records, co-worker affidavits from people who can identify Porter products at specific job sites, and records of Porter subsidiary operations at worksites in your history.
4. Your attorney prepares and submits the official claim package. The H.K. Porter Trust uses standardized claim forms under the TDP. Your attorney prepares the complete submission — claim form, medical documentation, exposure narrative, and supporting records — and files it with CMI.
5. Select a review pathway. Expedited Review provides efficient processing at the standard scheduled value. Given the low payment percentage, most claimants elect Expedited Review for speed. Individual Review is available for exceptional cases but rarely changes the outcome significantly at the 3% payment level.
6. Claim is reviewed and approved. CMI reviews the submission for TDP compliance. Approved mesothelioma claims are paid at the current 3% rate, yielding approximately $6,000 per claim.
7. Receive payment. The H.K. Porter payment is one component of a total recovery that typically includes payments from multiple other trusts and possibly civil litigation proceeds. Combined across all sources, total mesothelioma compensation often reaches $300,000 or more.

Can You File Other Claims at the Same Time?

Yes — and for H.K. Porter Trust claimants, multi-trust filing is particularly important given the trust's 3% payment rate. Workers who encountered H.K. Porter asbestos products — whether in textile mills, steel plants, refineries, or shipyards — invariably also worked in environments where asbestos products from many other manufacturers were present. The industrial settings where Porter products were used were typically saturated with asbestos from dozens of sources: insulation from Johns Manville, pipe covering from Owens Corning, gaskets from Garlock, refractory products from Christy or Harbison-Walker, and many others.

An experienced asbestos attorney will conduct a comprehensive work history review to identify every asbestos trust for which your exposure history creates eligibility. For workers in the steel, power, chemical, or maritime industries, this can mean qualifying for ten or more trusts simultaneously. Each trust files and pays independently, and total compensation from all trust claims combined — even where many individual trusts pay small percentages — can reach hundreds of thousands of dollars. If solvent defendants are also identified as contributing to your asbestos exposure, civil litigation remains available alongside trust claims, potentially adding substantially to your total recovery. There is no legal bar to receiving trust payments while litigation proceeds.
