Today, products used for potable water must comply with new lower lead standards…Are You Ready?

The Lead Free* Law

On January 4, 2014 the "Reduction of Lead in Drinking Water Act," more commonly known as the Lead Free law, went into effect. The national mandate requires that every pipe, fixture, and fitting used to convey water for potable use contain less than 0.25% of lead by weight.

Identify Lead Free Products

Mueller Steam Specialty has made it simple for you to quickly and easily identify Lead Free products and part numbers. We use a comprehensive set of identifiers to make compliance easier and help eliminate mistakes.

Look for LEAD FREE on labels, boxes and tags, and/or LF markings on the body of many of our Lead Free products.

The LF prefix will also appear as part of our part numbers when a standard version is also offered.


  • Traditional Product: 351M1
  • Lead Free* Product: LF351

NOTE: If a product is only available in a Lead Free version, the LF will not be present.

Look for the Lead Free Statement

Finding Lead Free* products couldn't be easier, simply look for the Lead Free statement. The Lead Free statement lets you know that Lead Free* models are available as part of that series.
