TOTO THP5116 – Frequently Asked Questions
1) What exactly is the TOTO THP5116 part?
THP5116 is the cartridge base O-ring for a TOTO single-handle faucet. It is a faucet valve cartridge service part, not the whole cartridge assembly and not the faucet body, so order it when the seal at the cartridge base is the source of a leak.
2) Will the TOTO THP5116 O-ring work on a two-handle faucet?
No. THP5116 is specified for a single-handle (1H) TOTO faucet cartridge base. Two-handle faucets use different stem and seal parts, so match the repair part to the faucet's own TOTO part number rather than substituting this one.
3) Do I need to order anything else with the THP5116 cartridge base O-ring?
It depends on what failed. THP5116 covers only the O-ring at the cartridge base. If the handle is stiff, weeping past the stem, or the mix temperature has drifted, the cartridge itself is the part to replace, and the O-ring alone will not fix it. For a drip at the joint between cartridge and faucet body, the O-ring is the correct part.
4) Is the THP5116 a genuine TOTO part or an aftermarket seal?
Genuine TOTO. THP5116 is TOTO's own part number for the cartridge base O-ring, which matters on faucet repairs because the seal has to match the cartridge and body machining exactly to hold pressure.
5) I manage a building with a lot of TOTO faucets. Is THP5116 a part worth stocking?
For a property with TOTO single-handle lavatory or sink faucets, yes. Cartridge base O-rings are a low-cost wear item that get replaced during routine faucet service, and THP5116 is the TOTO manufacturer part number, so it drops into the same repair on every matching faucet without hunting for a generic seal that may not seat correctly.
