TOTO THP5221 – Frequently Asked Questions

1) What exactly is the TOTO THP5221 part, and where does it go in a faucet?
THP5221 is the snap ring for the cartridge sleeve in a TOTO faucet. It is the retaining ring that holds the cartridge sleeve in place inside the valve body, not the cartridge itself. If you are rebuilding a TOTO single-hole faucet valve and the old snap ring is deformed or lost, this is the replacement piece.
2) Does the TOTO THP5221 include the faucet cartridge?
No. THP5221 is only the snap ring that retains the cartridge sleeve. The cartridge and sleeve are separate parts and have to be ordered on their own if yours are worn.
3) What part number do I order for the TOTO cartridge sleeve snap ring?
Order TOTO THP5221. That is the manufacturer part number for the cartridge sleeve snap ring, and it is the only configuration it comes in, so there is no finish or size to specify when ordering.
4) Is this TOTO snap ring a plumbing repair part or a trim piece?
It is an internal plumbing repair part. THP5221 sits inside the faucet valve as part of the cartridge assembly hardware, so nothing about it is visible once the handle and trim are back on. Buyers looking for a visible escutcheon or handle plate need a different part.
5) I manage a building with TOTO faucets. Is the THP5221 snap ring worth stocking for maintenance?
If your standard is TOTO faucets using this cartridge sleeve, yes. Snap rings are easy to lose or bend during a cartridge swap, and a rebuild stalls without one. It is a small, single-configuration item, so stocking a few alongside your cartridges keeps a service call from turning into a second trip.
