For decades, Moen's innovative yet simple standard cartridges have been used in one- and two-handle faucets. Today, we also offer our line of dependable Duralast® cartridges, which feature a ceramic disc, for use in many of our newer faucets.

In this module, you'll learn about all of our different cartridge options, beginning with our standard cartridges and ending with our Duralast models. You'll find descriptions of each cartridge's uses, construction and benefits as well as removal and installation instructions and quick-fix troubleshooting suggestions. As a result, you'll be equipped to work with all of our cartridges with assurance and ease.
