Single Handle Replacement Cartridge, 1225

The Moen 1225 is a single-handle replacement cartridge designed to restore smooth operation and stop leaks in Moen single-handle faucets. This OEM cartridge fits most Moen kitchen and bathroom faucets (excluding Posi-Temp and Exact-Temp models), delivering reliable temperature and flow control through a durable cast metal and plastic construction. When your faucet handle becomes difficult to turn or water drips from the spout, replacing the cartridge solves both problems without replacing the entire faucet. Built for professionals and DIY installers alike, the 1225 cartridge installs quickly and includes a twisting cap tool to simplify removal of the old cartridge.

• Cast metal and plastic construction: The cartridge combines cast metal components with engineered plastic for strength and durability that outlasts all-plastic aftermarket alternatives.
• Includes cartridge removal tool: A twisting cap ships with the cartridge to loosen and extract the old cartridge from the valve body, eliminating the need to purchase a separate puller tool.
• OEM Moen genuine part: This is the factory-original cartridge engineered to exact Moen specifications, ensuring proper fit and function in your Moen faucet.
• Single-handle temperature and flow control: The cartridge provides smooth one-handle operation for both water temperature (hot to cold) and flow volume (off to full), restoring precise control.
• Stops drips and leaks: Replacing a worn cartridge eliminates water dripping from the spout and leaking around the handle, saving water and preventing fixture damage.
• Works with most Moen single-handle faucets: The 1225 fits the majority of Moen single-handle kitchen and bathroom faucets installed over the past several decades, making it a universal repair solution for most households.

The Moen 1225 cartridge works with all Moen single-handle faucets except Posi-Temp and Exact-Temp shower valve models. This cartridge is the correct replacement for faucets where the handle pulls out to turn on water and rotates left or right to adjust temperature. It replaces earlier model 1225B cartridges (the 1225 and 1225B are identical, with the B designation used only for bulk packaging). Before installation, turn off water supply valves under the sink or at the main shutoff.

To install the Moen 1225 cartridge, remove the faucet handle and any retaining hardware, use the included twisting cap to loosen and extract the old cartridge, then insert the new cartridge with the brass stem facing up and secure it with the retaining clip. For smooth long-term operation, lubricate the cartridge inside and out with silicone-based grease (Moen part number 99915) before installation. Do not use plumber's grade faucet grease, silicone sprays, or any lubricant containing petroleum, as these can damage the cartridge seals.

The Moen 1225 cartridge is covered by a limited 1-year warranty from the date of purchase.

A: No, the 1225 and 1225B are identical cartridges with identical fit and function. The B version was packaged for bulk orders, but both part numbers refer to the same cast metal and plastic cartridge design. You can use either version interchangeably in any Moen single-handle faucet that specifies a 1225 cartridge.

A: Remove the cartridge from the faucet valve body and apply silicone-based grease (Moen part number 99915) to both the inside and outside surfaces of the cartridge before reinstalling. This lubrication reduces friction and ensures smooth handle operation. Never use plumber's grade faucet grease, silicone sprays, or petroleum-based lubricants, as these will degrade the rubber seals and shorten cartridge life.
