Army Equipment Asbestos Exposure: Armor, Vehicles, Generators & Heating Plants
The specific Army equipment that allegedly carried asbestos — tanks and armored vehicles, trucks and their brakes and clutches, field generators, and boiler and heating plants — and how soldiers who maintained it were exposed.
Asbestos earned its place in Army equipment for one reason: it survived heat and friction that would destroy almost anything else. Where an engine burned, a brake dragged, or a steam line ran hot, asbestos was allegedly there — molded into a friction facing, cut into a gasket, or wrapped around a pipe. The soldiers who kept that equipment running were the ones who disturbed those materials, and the ones most likely to breathe the dust.
This page looks at the equipment itself. For how exposure tracked with a soldier’s MOS, see Army exposure by job; for the buildings soldiers lived and worked in, see bases and barracks.
Tanks and Armored Vehicles
Tracked armor concentrated heat in a small, enclosed hull, and asbestos-containing materials were allegedly used to manage it. Engine-compartment gaskets, exhaust and manifold seals, and firewall and bulkhead insulation in tanks and armored personnel carriers were allegedly asbestos-based to resist the heat of a large powerplant working in a sealed space. Steering and braking on tracked vehicles relied on friction bands and clutches, and those friction elements were allegedly made with asbestos as well.
Armor crewmen who pulled maintenance in the field, and the tracked-vehicle mechanics who overhauled these systems in the motor pool, worked directly with those parts — scraping old gaskets, pulling friction components, and cleaning out compartments where settled dust had collected.
Trucks and Wheeled Vehicles: Brakes, Clutches, Engine Gaskets
The Army’s fleet of trucks, prime movers, and utility vehicles was maintained the same way civilian heavy vehicles were, and the exposure was the same.
- Brakes. Brake shoes and brake bands were allegedly made with asbestos friction material because it withstood the heat of stopping a loaded truck. Grinding, filing, or blowing out old brake assemblies with compressed air released asbestos dust directly into a mechanic’s breathing zone.
- Clutches. Clutch friction facings on manual-transmission vehicles were allegedly asbestos-based for the same heat-resistance reason. Replacing a worn clutch meant handling and sometimes machining those facings.
- Engine and exhaust gaskets. Head gaskets, manifold gaskets, and exhaust seals were allegedly cut from asbestos sheet or molded with asbestos fiber. Scraping a stuck gasket off a hot engine surface aerosolized the fiber.
Representative product records on our companion index, Asbestos-Products.com, document these material types from public litigation records:
- Heavy-truck brake linings (Bendix) — heavy-vehicle brake friction allegedly made with chrysotile asbestos
- Clutch friction facings (Bendix) — clutch discs allegedly containing chrysotile asbestos
- Caterpillar D8 brake bands & clutch friction — tracked heavy-equipment friction components allegedly containing asbestos
- Detroit Diesel exhaust-manifold gaskets — two-stroke diesel exhaust gaskets allegedly made with asbestos
Field Generators and Diesel Powerplants
Mobile power was everywhere the Army went — generator sets ran field kitchens, communications, motor-pool shops, and command posts. The diesel and gas engines that drove those generators used exhaust-manifold gaskets, cylinder-head gaskets, and heat shielding that were allegedly asbestos-based to survive the exhaust temperatures. Generator mechanics and prime-power specialists who tore down and rebuilt these engines disturbed those gaskets and seals.
- Detroit Diesel / Cummins diesel engines — industrial diesel engines with allegedly asbestos-containing gaskets and seals
- Cummins diesel exhaust-manifold gaskets — exhaust gaskets allegedly made with asbestos
- Caterpillar D398 diesel-engine gaskets — industrial diesel head and exhaust gaskets allegedly containing asbestos
Boiler and Heating Plants
Stateside posts, depots, and larger camps were heated by central boiler plants and steam distribution. The boilers, headers, valves, and miles of steam and hot-water piping were allegedly wrapped in asbestos block and pipe insulation and sealed with asbestos gaskets, rope, and packing. Utilities soldiers, boiler-plant operators, and maintenance crews cut this insulation to fit, tore it out during repairs, and remade the joints — every one of those steps could release fibers.
- Asbestos pipe & block insulation (Celotex) — thermal insulation allegedly used on boiler-room steam piping
- Kaylo pipe insulation (Johns-Manville) — high-temperature pipe insulation allegedly made with asbestos
- Compressed asbestos sheet gasketing (Crane Co.) — valve and flange gasket material allegedly cut from asbestos sheet
- Asbestos rope / packing — rope and packing allegedly used to seal valves, joints, and boiler doors
The Same Trades, In and Out of Uniform
A soldier’s exposure usually looked exactly like a civilian’s in the same trade. These occupation pages on Asbestos-Products.com describe the exposure pathway in detail:
If You Maintained Army Equipment and Have Been Diagnosed
A VA disability claim and a civil product claim are two separate paths, and they do not cancel each other out. A VA disability claim is filed directly with the U.S. Department of Veterans Affairs — it is a government benefit for a service-connected condition, not a lawsuit, and a Veterans Service Organization such as the DAV, VFW, or American Legion will help you file at no cost. See our VA claims guide for the steps.
A civil product claim is a separate matter against the private companies that made and sold the asbestos-containing products — never against the Army or the government. That is the lane an asbestos attorney handles, and it runs in parallel with VA benefits. If you served in the Army, were exposed to asbestos while maintaining its vehicles, generators, or heating plants, and have been diagnosed with an asbestos-related disease, you may have a legal claim against those manufacturers.
