Moen 100212 31mm Cartridge Assembly Single Handle Kitchen Lavatory Faucet Replacement 1255

Product Description

The Moen 100212 is a 31mm cartridge assembly designed as a direct replacement for single handle kitchen and lavatory faucets. This cartridge is a core internal component that controls both water flow and temperature in single-lever faucet designs. When a faucet begins to drip, leak, or becomes difficult to operate, the cartridge is almost always the root cause. Replacing it with the correct OEM cartridge restores smooth, reliable performance without the need to replace the entire faucet. This part is compatible with Moen faucets that use the 1255 cartridge, making it a widely used replacement in both residential and commercial plumbing service calls. Plumbers and maintenance technicians rely on cartridge replacements as a fast, cost-effective repair solution. The 31mm size refers to the diameter of the cartridge body, which must match the valve body precisely to ensure a proper seal and correct function. This cartridge meets AB1953 compliance standards, which restrict the lead content in plumbing components used in potable water systems. AB1953 compliance is required for installations in California and Vermont, and is recognized as a best-practice standard across the broader plumbing industry. Using a lead-compliant cartridge is essential for any kitchen or bathroom faucet that delivers drinking water. Moen cartridges are known for their consistent tolerances and durable construction, which translate to long service life after installation. This part is stocked by plumbing distributors and trade supply houses because of its high replacement frequency. Whether you are servicing a dripping kitchen faucet or a loose lavatory handle, the Moen 100212 cartridge assembly is the correct OEM replacement to restore full faucet function.
