Milwaukee Valve Company Asbestos Exposure: Navy & Industrial Valve Claims
Milwaukee Valve Company has manufactured plumbing, heating, industrial, commercial and marine valves since 1901. Historical asbestos litigation has named Milwaukee Valve in claims involving valve work, including Navy and industrial settings where asbestos-containing packing, gaskets and insulation were commonly used with high-temperature steam systems. The presence of a Milwaukee Valve product, however, does not by itself prove that a worker encountered asbestos supplied by Milwaukee Valve; the valve model, service, component source, maintenance history and dates must be established.
Milwaukee Valve remains an operating U.S. valve manufacturer and in 2026 celebrated its 125th anniversary. The company states that it serves commercial, industrial, marine and military markets and has supplied specialized valves for Navy shipbuilding programs. Current federal procurement records also document U.S. Navy purchases of Milwaukee Valve products. No Milwaukee Valve-specific §524(g) asbestos personal-injury trust was confirmed from primary company, government and court sources reviewed, so this page does not invent a bankruptcy date, trust payment percentage, disease schedule, trust assets or nationwide exposure count.
🏢 Milwaukee Valve Company History
Milwaukee Valve’s official company profile states that the business was established in Wisconsin in 1901 as a small manufacturer of plumbing and heating valves. Herschel Seder and Max Koenigsberg purchased the business in 1959. The company subsequently expanded into a broad range of commercial, industrial and marine valve products.

⚙️ Milwaukee Valves, Gaskets, Packing & Historical Asbestos
Valves used in high-temperature steam systems historically relied on packing around valve stems and gaskets between metal surfaces to control leakage. Published Navy asbestos decisions involving valve manufacturers explain that Navy specifications during portions of the twentieth century required asbestos-containing packing and gaskets for certain high-temperature applications. Those general Navy specifications provide important historical context, but they do not prove that every Milwaukee Valve contained asbestos or that Milwaukee Valve supplied every gasket or packing material later installed in one of its valves.
Historical Valve Components Requiring Investigation
| Component | Potential Historical Asbestos Issue |
|---|---|
| Valve-stem packing | High-temperature Navy and industrial valves historically could use asbestos-containing packing to seal around moving stems. |
| Bonnet / internal gaskets | Some historical steam-valve applications used asbestos-containing gaskets between metal surfaces. |
| Flange gaskets | Asbestos sheet gaskets were historically used between valves and adjoining piping, but could be supplied by third parties. |
| Replacement packing | Replacement material may have come from independent packing manufacturers or supply houses. |
| External insulation | Hot valves and adjoining piping could be insulated with asbestos-containing materials supplied by separate insulation manufacturers. |
| Modern components | Current Milwaukee Valve products and specifications must not be characterized as asbestos-containing based on historical evidence. |
Product Accuracy Table

🔧 How Historical Valve Asbestos Exposure Occurred
Published Navy valve cases describe maintenance activities that could release asbestos fibers: pulling old packing from valve stems, scraping or wire-brushing deteriorated gaskets from metal surfaces, cutting replacement sheet gaskets and removing external insulation. Whether a Milwaukee Valve claimant encountered asbestos attributable to Milwaukee Valve depends on evidence identifying the valve and the particular material disturbed.
Potential Exposure Activities
| Task | Potential Historical Exposure Mechanism |
|---|---|
| Repacking a valve stem | Removing deteriorated asbestos-containing packing could create dust. |
| Opening a valve bonnet | Could disturb an old internal gasket if that component contained asbestos. |
| Removing a valve from piping | Could disturb asbestos-containing flange gaskets. |
| Scraping gasket residue | Hand scraping or wire brushing could release fibers from old asbestos gasket material. |
| Cutting replacement gaskets | Historical sheet-gasket fabrication could create dust where asbestos sheet material was used. |
| Removing valve insulation | Could disturb third-party asbestos insulation on hot equipment. |
| Cleanup | Sweeping or compressed-air cleaning could redistribute settled 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. |
⚖️ Milwaukee Valve Asbestos Litigation & Current Status
Milwaukee Valve has been named in asbestos personal-injury litigation in multiple jurisdictions. A New York asbestos decision in Kelly v. Airco Welders Supply denied Milwaukee Valve’s motion for summary judgment, concluding that the company had not established entitlement to dismissal on the record before the court. Other cases have ended differently, including dismissals where plaintiffs did not oppose Milwaukee Valve’s motion. These different outcomes reinforce the need for claimant-specific product and exposure evidence.

📋 Milwaukee Valve Claim Evidence & Product Identification
A Milwaukee Valve asbestos investigation should identify the exact valve, vessel or facility, service dates and material disturbed. Navy procurement records, equipment lists, valve drawings, maintenance records and testimony may be especially important because replacement packing, gaskets and external insulation could have been supplied by companies other than the valve manufacturer.
Evidence That May Help Document Exposure
- Medical documentation establishing an asbestos-related disease.
- Navy service, ship assignment, employment, union or Social Security records.
- Milwaukee Valve nameplates, cast markings, model or figure numbers.
- Navy equipment lists, procurement records and technical manuals.
- Historical Milwaukee Valve catalogs and parts documentation.
- Valve maintenance and overhaul records.
- Invoices identifying packing, gasket or insulation manufacturers.
- Photographs of historical valves and piping systems.
- Shipmate or coworker testimony describing gasket scraping, packing removal or insulation work.
- Evidence establishing whether asbestos material was original equipment or a later replacement.
Product-Identification Checklist
| Step | Question |
|---|---|
| 1 | Was the valve positively identified as a Milwaukee Valve product? |
| 2 | What model, figure number or valve type was involved? |
| 3 | What system and temperature/pressure service used the valve? |
| 4 | Did the specific historical configuration contain asbestos packing or gaskets? |
| 5 | Was the material original to the valve or a later replacement? |
| 6 | Who manufactured or supplied the packing, gasket or insulation? |
| 7 | How frequently and closely did the claimant perform or observe dust-producing work? |
Compensation is not guaranteed. Claim viability and value depend on disease, product identification, exposure evidence, jurisdiction, available defendants or insurance and filing deadlines.
❓ Frequently Asked Questions
Did Milwaukee Valve manufacture valves used by the U.S. Navy?
Yes. Milwaukee Valve’s 2026 anniversary materials specifically state that the company supplied specialized valves for Navy shipbuilding programs, and federal procurement records document Navy purchases from Milwaukee Valve.
Did historical valves use asbestos packing and gaskets?
Many high-temperature Navy and industrial valves historically used asbestos-containing packing and gaskets. However, the composition of a particular Milwaukee Valve must be established from product- and date-specific evidence.
Did every Milwaukee Valve contain asbestos?
No such universal conclusion is supported by the primary sources reviewed. Valve type, application, manufacturing period and component materials must be investigated individually.
How could valve maintenance expose a worker to asbestos?
Historical exposure could occur while pulling old asbestos packing, scraping or wire-brushing gasket residue, cutting replacement sheet gaskets or removing asbestos insulation around hot valves and piping.
Were Navy replacement gaskets and packing always made by the valve manufacturer?
No. Published Navy asbestos cases show that replacement sealing materials frequently came from independent gasket and packing manufacturers. Product source is therefore an important claim issue.
