Moen 1200B, Single-Handle Replacement Cartridge, Brass

Moen 1200B Brass Cartridge – Single Handle Replacement for Standard Valve Systems

The Moen 1200B is a direct replacement cartridge designed for Moen single-handle faucets that utilize standard valve bodies. Constructed from brass for durability and corrosion resistance, this cartridge restores proper function to fixtures experiencing issues such as leaks, inconsistent water control, or reduced performance due to worn internal components.

Compatible with a range of Moen faucet models—including those in the Chateau series—the 1200B cartridge is engineered for long-term reliability and precise water flow control in residential or light commercial applications. It replaces older cartridges in non-pressure balancing Moen valve bodies.

Key Features

• Application: Single-handle lavatory, kitchen, and tub/shower faucets (non-posi-temp)
• Installation Type: For standard Moen valve bodies (non-cartridge balancing)
• Operation: Controls both temperature and flow with a 90° rotational movement

Technical Specifications

• Model: 1200B

Installation Considerations

Installation requires access to the valve body and basic plumbing tools. It is recommended that water supply lines be shut off prior to removing the old cartridge. Ensure the replacement is properly seated and aligned to prevent leaks or operational issues. Use silicone-based grease (not petroleum-based) for lubrication if needed during installation.

For professional applications, confirm compatibility with the specific Moen fixture model. This cartridge is not compatible with Moen Posi-Temp pressure-balancing valves (use Moen 1222 for those systems).
