In re Uponor, Inc., F1807 Plumbing Fittings Products Liability Litigation
This multidistrict litigation consists of cases in which the plaintiffs claim that the defendants' design and choice of materials for use in brass insert fittings for plumbing systems with cross-linked polyethylene (commonly known as "pex") tubing caused damage to the plaintiffs' property. Plaintiffs allege that these brass insert fittings are defective and highly susceptible to premature failure through processes such as stress corrosion cracking and/or dezincification. They allege this failure causes leaks and necessitates the replacement of the entire plumbing system well in advance of its warranted life.
Defendants Uponor, Inc. and subsidiary Radiant Technology, Inc. advertise, warrant, manufacture, and sell plumbing components including the brass insert fittings at issue. Defendants contend that the plaintiffs' claims lack merit, that the fittings are properly designed, and that the choice of materials in the fittings is not the cause of leaks or damage.
The Judicial Panel on Multi district Litigation determined that the Uponor cases involved common questions of fact, and that centralization of the cases in Minnesota was appropriate. All Uponor cases were transferred to the District of Minnesota for coordinated or consolidated pretrial proceedings. The cases are assigned to Judge Ann D. Montgomery. Any subsequent Uponor case filed in federal court will be transferred to the District of Minnesota and become part of MDL 11-2247 as a "tag along" case.
