Spirax Sarco Inc. Asbestos Exposure: Steam Traps, Navy Equipment & Claims
Spirax Sarco, Inc. has a long history in steam-system equipment, especially steam traps and controls. Its own history states that the American Sarco business was established in New York in 1907 and was offering steam traps and thermostatic regulators by 1915. Asbestos litigation involving Spirax Sarco requires careful product-specific analysis because published federal records include evidence concerning asbestos-containing internal and flange gaskets associated with historical Navy steam-trap installations, while another federal record states Spirax manufactured steam traps and radiator valves and had not itself manufactured asbestos-containing products.
Spirax Sarco remains an operating steam-engineering company. Modern Spirax Sarco steam traps include thermodynamic, thermostatic, mechanical and sealed designs and should not be described as asbestos-containing based on historical litigation. No Spirax Sarco-specific §524(g) asbestos personal-injury trust was confirmed from the primary company and court sources reviewed, so this page does not invent a bankruptcy date, trust payment percentage, disease values, trust assets or exposure totals.
🏢 Spirax Sarco Company History
Spirax Sarco’s official history states that Lewis Sanders arrived in New York in 1907 to establish the American branch of his British employer. The Sarco Fuel Saving and Engineering Company operated in Lower Manhattan and became Sarco Co. Inc. in 1915. Historical offerings included steam meters, steam traps and thermostatic regulators. The company’s own history says steam traps became a mainstay of its U.S. growth.

⚙️ Spirax Sarco Steam Traps, Gaskets & Historical Asbestos Issues
The most useful primary evidence comes from federal Navy litigation. In McAllister v. Air & Liquid Systems Corp., Spirax Sarco acknowledged that it sold three steam-trap types made specifically for Navy nuclear submarines: the FD2, TDN and TM600N. The record states that, to the extent a Spirax Sarco trap contained an internal asbestos gasket, exposure to that gasket would require opening and disassembling the trap. The court also discussed asbestos-containing flange gaskets used to connect these traps to Navy steam piping.
Historical Components & Attribution
| Component / Material | What the Record Supports |
|---|---|
| Internal steam-trap gasket | McAllister discusses the possibility of asbestos-containing internal gaskets in Spirax Sarco steam traps. |
| Flange gaskets | Historical Navy installations used flange gaskets connecting steam traps to piping; the litigation record discusses asbestos-containing flange gaskets. |
| Replacement sheet gasket material | McAllister states Navy replacement sheet gasket material was specified and supplied by others, not Spirax Sarco. |
| External insulation | Spirax Sarco maintained it did not recommend steam-trap insulation in the Navy litigation; insulation source must be independently established. |
| Steam traps | Core historical Spirax Sarco product; presence of a trap alone does not establish exposure to asbestos. |
| Radiator valves | A separate federal record identifies Spirax as a manufacturer of steam traps and radiator valves and states it had not manufactured asbestos-containing products. |
Navy Steam-Trap Models Identified in Federal Litigation
| Model | Documented Context |
|---|---|
| FD2 | Made specifically for and sold to the Navy; federal record discusses replacement of asbestos-containing flange gaskets if they leaked. |
| TDN | Made specifically for and sold to the Navy; record states it required the same type of flange-gasket connection discussed for FD2. |
| TM600N | Made specifically for and sold to the Navy; record states it required the same flange-gasket arrangement. |
Accuracy note: The evidence does not support describing every historical Spirax Sarco product as asbestos-containing. It also does not support attributing every gasket, sheet gasket or insulation product used with a Spirax Sarco trap to Spirax Sarco.
⚓ Navy & Industrial Workers Potentially Exposed

🔧 How Historical Spirax Sarco-Related Exposure Occurred
In McAllister, the Navy veteran testified that he removed old steam traps and installed new traps rather than rebuilding their interiors. His potential exposure involved scraping old flange-gasket remnants from steam pipes. The record describes Navy workers cutting custom replacement gaskets from asbestos-containing sheet material and removing old gasket residue with scrapers, wire brushes or pneumatic wire brushes, creating dust. The central product-attribution issue was whether Spirax Sarco supplied or specified the asbestos-containing material being disturbed.
Potential Exposure Activities
| Task | Potential Historical Exposure Mechanism |
|---|---|
| Removing a steam trap | Could require disturbing old flange gaskets at pipe connections. |
| Scraping flange surfaces | Could release dust from deteriorated asbestos-containing gasket residue. |
| Wire-brushing gasket residue | Federal Navy testimony describes this as a dust-producing maintenance activity. |
| Cutting replacement sheet gaskets | Historical Navy workers could create dust while fabricating asbestos sheet gaskets supplied by others. |
| Opening a steam trap | Could potentially disturb an internal gasket if the specific trap used an asbestos-containing internal component. |
| Removing insulation | Could disturb third-party asbestos insulation around steam piping or equipment. |
| Nearby maintenance | Confined machinery spaces could expose nearby workers to gasket or insulation dust. |
Asbestos-Related Health Conditions
| Condition | General Relationship to Asbestos |
|---|---|
| Mesothelioma | A rare cancer strongly associated with asbestos exposure. |
| Lung cancer | Occupational asbestos exposure can increase lung-cancer risk. |
| Asbestosis | Progressive pulmonary fibrosis caused by inhaled asbestos fibers. |
| Pleural disease | Asbestos exposure can cause pleural plaques, thickening and other abnormalities. |

📋 Spirax Sarco Claim Evidence & Product Identification
A Spirax Sarco asbestos investigation should identify the steam-trap model, vessel or worksite, dates of service and the exact material disturbed. The litigation record demonstrates that identifying the steam trap alone may not identify the manufacturer of an asbestos-containing flange gasket, sheet gasket or insulation product.
Evidence That May Help Document Exposure
- Medical documentation establishing an asbestos-related disease.
- Navy service, ship assignment, employment or union records.
- Steam-trap manufacturer markings and model numbers.
- Ship equipment lists, Navy technical manuals and procurement records.
- Historical Spirax Sarco catalogs, drawings and parts documentation.
- Maintenance records showing trap removal or rebuilding.
- Evidence identifying internal gasket composition for the specific model and period.
- Invoices or supply records identifying flange or sheet-gasket manufacturers.
- Shipmate or coworker testimony describing scraping, wire brushing or gasket cutting.
- Evidence distinguishing Spirax Sarco components from third-party asbestos products.
