TOTO THP4019 – Frequently Asked Questions
1) What size is the TOTO THP4019 gasket?
The THP4019 is a ring gasket measuring 41.5 mm outside diameter, 34.5 mm inside diameter, and 1.5 mm thick. Those three numbers are what decide whether it seats in your handle assembly, so measure the old ring's OD and bore before ordering, especially the 34.5 mm ID over the spindle.
2) Is TOTO THP4019 the whole handle assembly or just a seal?
It is a single gasket, not a handle or a complete spindle assembly. If your repair needs the handle, the stem, or a cartridge, those are separate TOTO part numbers; THP4019 only covers the 1.5 mm thick sealing ring.
3) How do I order the correct TOTO repair gasket for a faucet handle?
Order by TOTO's own part number rather than by description, since TOTO uses many similar ring gaskets. THP4019 is the 41.5 mm OD / 34.5 mm ID / 1.5 mm ring. Pull the part number off the trim's service sheet, or compare your removed ring against those three dimensions.
4) Can a property manager stock TOTO THP4019 as a general purpose O-ring?
No. It is a flat ring gasket at 1.5 mm thickness with a 41.5 mm OD and 34.5 mm ID, dimensioned for a specific TOTO bath fitting, not a round-section O-ring you can cross from a generic kit. For fleet stocking, match it to the specific TOTO trim you have across the building.
