Aldyl‑A Gas Pipes: A Hidden Explosion Risk in Utah Homes
Across Utah, families may be living just above a silent and aging danger: Aldyl-A plastic gas pipes. Manufactured by DuPont and widely installed in distribution systems during the 1960s, 1970s, and early 1980s, Aldyl-A was once seen as a modern, corrosion-resistant alternative to steel. But over time, certain older versions of Aldyl-A have been found to be susceptible to premature brittle-like cracking, as the inner pipe wall becomes brittle and develops cracks under stress.
This risk is not theoretical. In November 2024, a tragic explosion in South Jordan, Utah, killed a 15-year-old and destroyed the family’s home. Preliminary reports from the National Transportation Safety Board (NTSB) indicate the gas leak came from a 4-inch Aldyl-A main installed in 1976, about 150 feet from the house. The incident is still under federal investigation, but it highlights the serious danger linked to aging plastic pipeline materials.
We represent Utah families impacted by catastrophic injury, wrongful death, and unsafe infrastructure. Our legal team is deeply experienced in explosion cases involving gas utilities, contractors, and manufacturers, and we hold them accountable when preventable tragedies occur.
How Aldyl-A Fails And Who Is At Risk
Certain vintages of Aldyl-A, especially pre-1973 “low ductile inner wall” (LDIW) versions, have been shown to experience slow crack growth and brittle-like failures. Tiny fractures in the pipe wall can expand over time, eventually allowing gas to escape underground. If that gas reaches a structure and finds an ignition source, the result can be a sudden and devastating explosion.
Neighborhoods built during Utah’s housing boom in the 1970s and 1980s are particularly likely to contain Aldyl-A gas lines, though homeowners are rarely informed of the pipe material beneath their homes. Residents often have no idea they are at risk.
Under federal safety regulations, gas utilities are responsible for monitoring, addressing, and, where appropriate, replacing high-risk materials such as Aldyl-A. However, replacement has been inconsistent across operators, and oversight varies significantly by region.
Decades of Warnings But Ongoing Danger
The Pipeline and Hazardous Materials Safety Administration (PHMSA) has issued multiple advisory bulletins since the 1990s warning operators about the risks of older plastic gas pipes, including Aldyl-A. In fact, DuPont alerted gas companies as early as 1982 and 1986 about brittle-like cracking and related hazards in its Aldyl-A products. Despite these long-standing concerns, incidents tied to Aldyl-A continue to happen, often with catastrophic results.
Why Legal Action Must Happen Quickly
In the aftermath of a gas explosion, critical evidence can be lost. Utilities may replace damaged pipe segments before they can be independently tested. Maintenance records, leak logs, and faulty fittings may disappear or degrade over time. That’s why it’s essential to involve legal counsel as soon as possible—to preserve evidence, coordinate expert investigations, and protect your rights.
We work with pipeline engineers, fire investigators, and utility safety experts to determine what went wrong and who is legally responsible. Our team has secured some of the largest wrongful death and catastrophic injury verdicts in Utah, and we approach each case with precision, compassion, and an unshakable commitment to justice.
If you or someone you love was injured in a gas explosion or residential fire, especially in a home built in the 1970s or 1980s, you may have a legal claim involving Aldyl-A pipeline failure.
These cases are complex, but you don’t have to face them alone.
