Description
Product Overview
Stop your dripping Moen shower faucet without replacing the entire expensive cartridge. The iFJF Moen 96988 Cartridge Repair Kit provides all internal wear components — seals, springs, O-rings, and stem assembly — to rebuild your existing Moen 1222 or 1222B Posi-Temp/Moentrol cartridge. If your shower handle is stiff to turn, won't hold temperature, or drips constantly, the internal seals have worn out — not the cartridge body. This kit restores smooth operation and leak-free performance at a fraction of the cost of a full cartridge replacement.
Key Features

-
Complete Internal Rebuild — Kit includes all wear components: seals, springs, O-rings, internal stem assembly, and retaining hardware. Everything that wears out is replaced.
-
Stops Drips & Leaks — New seals and O-rings eliminate water waste, prevent faucet dripping, and stop leaks from the handle area.
-
Restores Smooth Handle Operation — Eliminates the stiff, hard-to-turn handle feel and temperature fluctuation that develop as internal seals wear and bind.

Why Choose This
A brand-new Moen 1222B cartridge costs $50-70+ at hardware stores. In 90% of cases, it's only the internal seals and O-rings that wear out — the brass cartridge body itself is perfectly fine. This repair kit costs significantly less and delivers the same result: a drip-free, smoothly operating shower faucet. Moen cartridges are designed to be rebuildable; this kit uses that design feature to save you money. Plus, reusing your existing cartridge body means no risk of disturbing the valve body or plumbing connections behind the wall.

Frequently Asked Questions
Q: Does this replace the entire Moen 1222 cartridge?
A: No — this is an internal rebuild kit. It replaces the wear components (seals, springs, O-rings, stem assembly) inside your existing cartridge. If your cartridge body itself is cracked, physically damaged, or heavily corroded, you need a complete replacement cartridge.
Q: How do I know if I have a Moen 1222 or 1222B cartridge?
A: If your Moen shower handle pulls out to turn on the water and rotates left/right for temperature control, you have a Posi-Temp valve with the 1222 or 1222B cartridge. Look for "Moen" on the escutcheon plate. The 1222B is the updated version — this kit works with both.
Q: Will this stop my faucet from dripping?
A: Yes — if the dripping is caused by worn internal seals and O-rings (which covers roughly 90% of Moen cartridge drip issues). The kit includes all the sealing components that degrade over time.
Q: How difficult is the installation?
A: Moderate DIY difficulty. You'll need basic tools (screwdrivers, pliers, Allen wrench). The critical step is removing the cartridge from the valve body — Moen makes a cartridge puller tool (sold separately) that simplifies this significantly. Watch a tutorial video before starting if you haven't opened a shower valve before.
Q: What's the difference between 1222 and 1222B?
A: The 1222B is the updated/revised version of the 1222 cartridge with minor design improvements. Both are physically interchangeable in the same valve body. This kit works with either version.
Q: Do I need to shut off the main water supply?
A: Yes. Turn off the water supply to the shower/tub before removing the cartridge. There is usually no individual shutoff for the shower — you'll need to shut off the main house water or the branch line serving that bathroom.
Q: How long do Moen cartridge seals typically last?
A: In areas with hard water, seals may start degrading in 5-8 years. With soft water, they can last 10-15 years. Signs of wear include: handle stiffness, difficulty maintaining temperature, water dripping from the spout, and leaks around the handle area.
