Duro Dyne Asbestos Trust Claims

If you spent your career in sheet metal or HVAC work and later developed mesothelioma or another asbestos disease, the flexible duct connectors you handled may be the reason, and the company that made them, Duro Dyne, left behind a trust built to pay exactly these claims.

For decades, Duro Dyne was the name on the flexible duct connectors used in heating and air-conditioning systems across the country, the fabric-and-metal strips that join a blower to the ductwork and keep its vibration from traveling through the system. From the early 1950s until 1978, the fabric in those connectors was asbestos cloth, and the sheet-metal and HVAC workers who cut, stapled, and installed them breathed the fiber that came off. The volume of asbestos sickness eventually drove the company into bankruptcy, and its reorganization required it to set aside more than $47 million in a trust that's been paying mesothelioma and other asbestos claims since 2022. That trust is open, well funded, and still paying.

You don't need to have kept records, and you don't need the part numbers off the connectors you used. If you worked sheet metal or HVAC, the trust already recognizes your trade as one of the jobs its asbestos exposed, and reconstructing the rest, from work history and the trust's own rules, is our job, not yours. If you can tell us the work you did and when, we have a place to start.

What the Duro Dyne trust pays

For mesothelioma, the Duro Dyne trust's scheduled value is about $147,000, the amount it pays before its payment percentage is applied, which we explain further down. Duro Dyne is unusual in that it pays a single set value for each disease level rather than a negotiated range, and it raises those values by 1% a year. Mesothelioma sits at the top of the trust's five-level schedule:

The values shown are the trust's scheduled values effective January 1, 2026; the trust raises them 1% a year, so they tick up slightly each January. The two lung-cancer levels differ by the medical evidence required, and the trust's only non-malignant level is severe asbestosis, with strict breathing-test and imaging criteria; milder asbestosis and pleural-only conditions don't have a level of their own here.

Two things to keep in mind reading that table. First, every figure is reduced by the trust's payment percentage before it reaches you, which is how the fund lasts for the people still to be diagnosed; we explain that below. Second, the Duro Dyne connectors were rarely the only asbestos a sheet-metal or HVAC worker handled, so the same career usually supports claims against other trusts and defendants too. For many people the Duro Dyne claim is one clean, well-documented piece of a larger recovery.

How Duro Dyne's products exposed workers to asbestos

Duro Dyne made the accessories that sheet-metal shops and HVAC installers used every day. The company started in 1952 and built its name on the flexible duct connector, a strip of fabric bonded between two strips of sheet metal that gets installed between a fan or blower and the metal ductwork to keep the equipment's vibration and noise from traveling through the system. From the early 1950s until 1978, the fabric in the asbestos versions of those connectors was asbestos cloth. The company also sold an asbestos-containing duct sealer.

A connector like that doesn't release much fiber sitting in its carton. It got into the air when the people who used it worked it: measuring and cutting the connector to length, stapling and seaming the fabric, and fastening the assembly into the duct run, often overhead in a tight mechanical space. Cutting asbestos cloth sheds fiber the same way cutting any asbestos product does, and the work was done by hand, without warnings or protection, in shops and on job sites where the dust hung in the air.

Because Duro Dyne's products were sheet-metal accessories, the people who breathed their fiber were overwhelmingly the sheet-metal and HVAC trades: the sheet metal workers who fabricated and hung the ductwork, the HVAC installers and technicians who put the systems in and serviced them, and the duct and furnace installers who worked alongside them. The trust recognizes this directly, which is why its rules name these trades specifically. We come back to that below.

A Duro Dyne claim is also rarely a claim about Duro Dyne alone. A working life in sheet metal and HVAC meant a building full of other companies' asbestos, the pipe and duct insulation, the boiler and furnace components, the gaskets, cement, and sealants, and the same career that exposed a worker to Duro Dyne connectors usually exposed him to those products too. We come back to that below as well, because it's where much of the recovery is.

How the Duro Dyne bankruptcy created the asbestos trust

By 2018, Duro Dyne faced thousands of asbestos lawsuits from people exposed to the asbestos cloth in its products. Like many companies in that position, it used Chapter 11 bankruptcy, the kind that lets a business reorganize instead of shutting down, together with a part of the bankruptcy law written specifically for asbestos, Section 524(g).

That section lets a court set up a trust to take over a company's asbestos liability and then issue a channeling injunction, a court order that routes every asbestos claim, the ones already filed and the ones still to surface, away from the company and into the trust. The trade is straightforward: the company funds the trust, and in return it's protected from being sued over asbestos again. Duro Dyne filed in 2018, and the court confirmed its reorganization plan and established the trust at the end of 2020.

The company funded the trust well. Between cash from the business and its owners, a note that was paid off early, and the proceeds of its old insurance, the trust was funded with more than $47 million, and all of it was paid in by 2021 rather than promised out over time. That up-front funding is part of why the trust has been able to pay a relatively high percentage and still grow its reserves, which we come back to below.

The company is still in business today. The bankruptcy didn't shut Duro Dyne down. The trust took on the asbestos liability, which let the company reorganize and keep operating, and Duro Dyne is still the leading maker of sheet-metal and HVAC accessories today, the same family business it has been since 1952. That matters for two reasons. The records and history behind your exposure still exist. And because the trust, not the operating company, pays these claims, filing yours doesn't take a dollar from anyone working there now.

What the Duro Dyne trust pays, and why it's a percentage

The trust pays a set amount based on your diagnosis, scaled to how serious the disease is, with mesothelioma at the top of the schedule and the other conditions lower down. The full breakdown is in the table near the top of this page.

What's different about Duro Dyne is how clean it is. Most asbestos trusts make you choose between a fast fixed payment and a slower, evidence-heavy track that can pay more. Duro Dyne doesn't. It pays a single scheduled value for each disease level, full stop. If your diagnosis and your exposure to Duro Dyne's asbestos connectors qualify, the claim is paid the set amount for your disease, with no negotiation and no second track to weigh. For families, that makes a Duro Dyne claim unusually predictable: once we know the diagnosis, we can tell you closely what the trust will pay.

What it pays isn't the full scheduled value, though. Like every asbestos trust, it pays a percentage of that value, currently 20%, or about twenty cents on each dollar.

That number surprises people, so here's why it's there. It's the same principle behind every bankruptcy: when a company can't cover everything it owes, the law shares what there is across everyone it harmed, so everyone gets a fair portion instead of a lucky few collecting in full and everyone else getting nothing. An asbestos trust has to do that across time as well, because these diseases can take thirty to fifty years to surface, so the trust holds back enough for the family that won't be diagnosed until 2045.

By asbestos-trust standards, though, 20% is a strong rate, and it reflects a fund that was paid in early and in full rather than stretched out as promises. The trust reviews the percentage periodically, and it's reviewing it now: in a July 10, 2026 notice, the trustee proposed raising it to 40%, a change that takes the consent of the committees representing current and future claimants. Until that's decided, the trust is paying 20%. We confirm it against the trust's current terms when your claim is filed rather than relying on a figure that might be out of date. But a 20% rate on a clean scheduled value is the kind of number that lets us tell you with real confidence what a Duro Dyne claim is likely to pay.

Is the Duro Dyne trust still able to pay?

Yes, and this is one of the healthier asbestos trusts you'll deal with. Here's the picture from its most recent annual report.

• More than $48 million on hand. At the end of 2025 the trust held over $48 million in net assets, which is more than it was originally funded with. A young trust that's grown its reserves while paying claims is a fund in good shape.
• It grew in 2025. Over the year, the trust's investment returns ran well ahead of what it paid in claims and expenses, so the fund increased rather than shrank.
• A strong, stable percentage. The trust pays 20% of each claim's scheduled value, a high rate by asbestos-trust standards, and it's still early in its life, having only started paying claims in 2022.

None of that means the money is unlimited, and the percentage is exactly how the trust keeps its promise to the people who haven't gotten sick yet. But a Duro Dyne claim filed today is paid on a current, well-funded schedule, and we track the annual reporting and walk through the full financial picture in our analysis of the Duro Dyne trust's finances.

Who qualifies for a Duro Dyne trust claim

A trust claim rests on two things: a qualifying asbestos diagnosis, and proof that you worked directly with Duro Dyne's asbestos products. The diagnosis side is medical. The exposure side is where the trust's rules come in, and they're more specific than most.

There's no cutoff date. Unlike many asbestos trusts, Duro Dyne doesn't require your exposure to fall before a particular year. What matters is that you worked with its asbestos connectors, not when. As a practical matter the asbestos versions were sold from the early 1950s until 1978, so that's the era the claims come from, but you won't be turned away because your dates fall on one side of a line.

**For mesothelioma, you don't need heavy exposure.*Mesothelioma can come from limited exposure, and the trust recognizes that: a meso claim doesn't have to clear the higher dose threshold that applies to the other diseases. What a meso claim does need is the trust's standard of exposure, that you worked directly with Duro Dyne's asbestos flexible duct connectors. For a sheet-metal or HVAC worker, that's the ordinary case, not a high bar. The higher threshold for the other diseases, Significant Occupational Exposure (SOE), is about five years of asbestos work and applies to the lung cancers and the other cancers; it can count work done near the dust, not only handling the material yourself.

The trust's only non-malignant level is severe asbestosis. Duro Dyne pays asbestosis only at a severe level, defined by strict breathing-test and imaging criteria. Milder asbestosis and pleural-only conditions like plaques or thickening don't have a payment level of their own here, though they can still matter to a lawsuit or to another trust, which is part of why we look at the whole picture.

Family members may qualify too. If a Duro Dyne worker brought the dust home, a spouse who laundered the work clothes or a child in the household may file on the worker's exposure history.How take-home asbestos exposure works.

How the trust's qualifying occupations work

Most asbestos trusts identify exposure by worksite. Duro Dyne does it by trade. Because the company made sheet-metal and HVAC accessories, its trust names a specific set of occupations it already treats as the jobs its asbestos exposed: sheet metal mechanics, workers, and apprentices, HVAC repairmen, installers, and technicians, and duct and furnace installers. If you worked one of those trades and worked directly with Duro Dyne's asbestos connectors, your exposure fits the pattern the trust was built to pay, and the claim runs smoothly.

If your job isn't on that list, you're not shut out. The trust has a separate path for workers in other occupations who can show they worked directly with Duro Dyne's asbestos connectors anyway; if you can document that exposure, the claim is approved and paid the same scheduled value. The difference is just how much we have to show. For a recognized trade, the work history largely speaks for itself; for another occupation, we document the direct contact with the product. Either way, the question the trust asks is the same: did you actually work with the asbestos connectors?

How a Duro Dyne claim gets filed

A trust claim isn't a lawsuit, and that surprises people who expect a courtroom. There's no judge, no jury, no deposition, and no defense lawyer arguing the other side. You're submitting a documented claim to a fund that already exists to pay it, and the trust reviews it against its written rules and pays the scheduled value for your disease.

What the claim needs is proof of two things: your diagnosis, and your work with Duro Dyne's asbestos products. Putting that together is our job, not yours. We gather the medical records, reconstruct the work history, match it to the trust's occupation and exposure rules, and file. You don't need to have kept paperwork or remember product numbers to start.

The Duro Dyne trust has been paying claims since 2022 and is still accepting them today, so the door is open. The fuller mechanics of how trust claims are prepared, filed, and paid are laid out in ourguide to how asbestos trust claims work. When you call, we'll tell you what your specific claim is likely to involve and how the timeline tends to run.

A Duro Dyne claim is rarely the only one

Here's the part that changes the math for most families: the Duro Dyne trust is usually one claim out of several, and the others come from the very same work.

Start with the trade. A sheet-metal or HVAC worker didn't only handle Duro Dyne connectors. The same job sites were full of other companies' asbestos, the pipe and duct insulation, the boiler and furnace components, the gaskets, the cement and sealants, much of it made by companies that also went bankrupt and left their own trusts. The career that exposed a worker to Duro Dyne's asbestos cloth almost always exposed him to a stack of other asbestos products at the same time.

The same history that supports your Duro Dyne claim usually supports claims against several of those other trusts, and because each trust reviews and pays independently, the claims don't compete with each other. They add up.How asbestos trust claims work.

A Duro Dyne claim makes a strong, clean anchor for that larger case: a recognized trade, a specific product, a well-funded trust paying a high percentage. But it's an anchor, not the whole of it. We walk through a full worked example, several trusts totaled across one career, in ourguide to mesothelioma trust settlement values. The full set of channels beyond the trusts is laid out next.

Sources of compensation beyond the Duro Dyne trust

A Duro Dyne claim usually sits inside a larger recovery, and the channels run in parallel without canceling one another out. We file across all of them that apply.

• Asbestos bankruptcy trusts. Duro Dyne is one, and as the section above explains, a sheet-metal or HVAC career almost always reaches several others. They review and pay independently, so they stack.How asbestos trust claims work.
• Lawsuits against solvent manufacturers. Many of the other companies whose asbestos a sheet-metal or HVAC worker handled are still in business and can be sued directly for making and selling a product they knew was dangerous, and a lawsuit can recover more than a trust claim, though it takes longer.How asbestos product liability lawsuits work.
• Premises liability against the site owners. The plants, buildings, and facilities where this work was done can be held responsible for the conditions they allowed, separate from the companies that made the products.How premises liability claims work.
• Federal and disability benefits. These depend on where and how the work was done, and they're paid on top of the trust and lawsuit recovery. Military service, including sheet-metal and ventilation work aboard ships, can support VA disability benefits; civilian shipyard work can support Longshore benefits (LHWCA, the federal program for maritime and harbor workers); civilian work at a federal facility can support FECA benefits (the Federal Employees' Compensation Act); and Social Security disability is available to anyone whose illness stops them from workingHow asbestos disability and benefit claims work.

Your Duro Dyne trust claim has no defenses to answer. It's a paper claim: no opposing lawyer, no deposition, no courtroom, no one arguing the other side. Duro Dyne settled that question when it funded the trust, and the trust either pays the claim or it doesn't, on its written rules.

Defenses only come up on the lawsuit side, the claims that run alongside the trust against the manufacturers still in business and the site owners where you worked. Those defendants raise the same handful of arguments they raise in most asbestos cases, and none of them is new to us. The short version is that each one describes a cleaner, smaller version of the work than the one your loved one actually did, and the evidence answers it.
