Uponor Defective Brass Pipe Fitting Class Action Settlement – Ends 10/22/2022
There is a Settlement in a class action lawsuit filed against Uponor and certain developers/builders, subcontractors, and distributors/suppliers. The lawsuit claims that Uponor’s high zinc content brass plumbing fittings and components are defective and prematurely corrode (or break down).
The defendants have agreed to pay a maximum of $21 million to settle the nationwide class action lawsuit, and a minimum of $7 million to settle the Nevada class action lawsuit. This money will be paid into a settlement fund that will be used to reimburse eligible Class Members for repairs or replacement costs relating to leaks or flow issues, and related property damage. The amount each Class Member will receive depends on the type of claim they have. The defendants have agreed to pay a maximum of $60,000 per claim for property damage claimants in the nationwide lawsuit settlement, and up to $150,000 per claim in the Nevada settlement.
Uponor defective brass pipe fitting class action settlement. High-zinc-content brass is primarily made of copper and contains at least 30 percent zinc. The Uponor yellow brass fittings named in the class action lawsuits were made of UNS C36000, C3770 or C35330 brass or similar copper alloys. They were used as components of the Uponor/Wirsbo PEX system.

FAILURE ANALYSIS
HDPE PIPE JOINT FAILURE EXPERTS
The failure of electrofusion or butt fusion joints in polyethylene gas pipework can be due to several factors including incorrect alignment, contamination, incorrect temperature or the duration of joint fusion.
If a joint failure occurs, investigations are important to help identify modifications to procedures or training that can help you minimise the occurrence of future failure. This is where we can help.
We provide a detailed PE joint failure investigation service which typically include:
- Digital inspection of the received sample, including dimension measurements of sizes and ovality
- Segmenting the joint for visual and microscopic investigation
- Elemental analysis of any contamination found in the joint
- Peel decohesion testing

ExcelPlas Labs Pipe Failure Investigations
ExcelPlas Labs have created a new benchmark in failure analysis of HDPE, PP-R, PB and PEX pipes in addition to PVC & CPVC pipes as well as composite GRP and GRE pipes. When a plastic pipeline fails to perform as intended, our team can determine the root cause of failure (e.g. oxidative failure, chemical failure, creep failure, over-stress failure, fatigue failure, design failure, etc). ExcelPlas are experienced with all plastic piping failure modes and mechanisms including Slow Crack Growth (SCG) Rapid Crack Propagation (RCP), Environmental Stress Crack Resistance (ESCR), Oxidative Stress Cracking (OSC), cyclic fatigue, manufacturing defects, and polymer material problems.

ExcelPlas Strain Hardening Test (SHT) for HDPE Pipes
The SHT in accordance with ISO 18488 is a relatively new, but excellent way to obtain a rapid indication of the Stress Crack Growth (SCG) resistance of your piping material. This tensile test performed at 80°C has become in just a few years the new standard for Batch Release Testing (BRT). And not without reason. The test requires only a very small amount of material, the results are very reliable with a very low inter-laboratory scatter and the results are available within a few days, regardless of the PE grade. The SHT is usually performed on resin material but it can also be performed on samples taken directly from pipes or sheets. As accredited lab, EXCELPLAS is happy to discuss the possibilities with you, whether it is for BRT, benchmarking, quality control of your (high performing) PE grade or for polymer compliance/ validation.

ExcelPlas Poly Pipe Weld Inspection Lists Top 7 Causes of Weld Failure:
- Lack of scraping
- Inaccurate scraping
- Contamination from dirt, water, oil or clays
- Lack of Paralell-ness of fusion faces
- Misalignment of surfaces
- Time, temperature and pressure deviations
- Not adhering to cool times
We have extensive experience in inspection of poly pipe welds for assuring welded joint quality. Direct Poly Pipe Inspection ensures that operators are following the proven welding procedure; this reduces the occurrences of operational errors which lead to defects such as inclusions, lack of fusion (LoF), porosity and misalignment.
