Hey guys,
I have a 2-handle bathroom faucet (builder-grade, no brand visible). The hot side doesn’t stop at 90° anymore — it keeps turning and reopens.
I took it apart and found this small black plastic piece (handle/stem insert) is worn. Looks like it’s supposed to create the stop.
I don’t need the full cartridge, just this small insert piece if possible.
Does anyone know:
- What this part is called exactly?
- Where I can buy it?
- Or if there’s a universal replacement?
I attached pics of:
- Faucet
- Inside of handle
- The black piece I removed
Appreciate any help 🙏
