Will it fit?

Is this your part?
Pull the handle and bonnet nut and look at the stem. A ceramic disc stem turns a quarter turn stop to stop and has no rubber washer on the bottom. It has a broached top for the handle, one O-ring, and a tab at the base that locates it in the valve body. If yours turns through several full rotations and has a washer held by a screw, it is a compression stem.
When to replace it
The spout drips after the handle is closed, the handle needs extra force to shut off, it has gone stiff or gritty, or it spins without controlling flow.

How to install it
Time: About 15 minutes. Tools: Screwdriver, Deep socket or stem wrench.
- Shut the supply stops under the sink and open the faucet to bleed pressure.
- Pop off the index cap, back out the handle screw and lift the handle away.
- Unthread the bonnet nut with a deep socket or stem wrench.
- Draw the old stem straight out.
- Seat the new stem with the base tab dropped into its slot. If the tab is not indexed, the handle stops in the wrong place and the stem never fully closes.
- Thread the bonnet nut down and refit the handle.
Questions
Do I need seats and springs with this stem?
No. Ceramic disc stems seal internally and do not use seats and springs.
Does it matter which side it goes on?
No. The same stem works in the hot or cold position.
Why does the new stem still drip?
The base tab is usually not in its slot. Pull it and reseat it with the tab indexed.
Is it lead-free?
Yes. It is certified to NSF/ANSI/CAN 372 by IAPMO R&T.
Is there a 2-pack?
Yes. The FourHome 2-pack (Amazon ASIN B0H7TB2XBT) holds two stems, one for the hot side and one for the cold.
