The AMERICAN PLUMBING PARTSMASTER 988018IMP is an import-grade replacement cartridge designed to fit Moen 1200 series single-handle faucets. Cartridges are the core valve component in single-handle faucets, controlling both water flow and temperature by rotating within the faucet body. This replacement is intended for plumbers and experienced DIYers performing routine faucet repair or refurbishment, restoring proper function to a dripping or hard-turning handle without requiring a full faucet replacement.
This cartridge is suited for residential plumbing applications where Moen 1200 series single-handle faucets are installed, commonly found in kitchens and bathrooms. It is a practical choice when the original cartridge shows wear, causes dripping at the spout, or results in difficulty adjusting water temperature. Installation is straightforward and typically does not require specialty tools beyond standard plumbing hand tools.
Designed as a replacement-style cartridge for Moen 1200 series single-handle faucets. Verify the existing cartridge series against your faucet model documentation before installation to confirm fitment.
Cartridge replacement is performed by licensed plumbers or qualified service professionals. Shut off the water supply at the stop valves beneath the fixture or at the main shutoff before beginning any disassembly. Remove the faucet handle and bonnet nut to access and extract the existing cartridge, noting the orientation before pulling it free. Reinstall the new cartridge in the correct orientation and verify for leaks upon restoring water supply.
