TOTO THP4737 – Frequently Asked Questions
1) How do I make sure I order the right TOTO O-ring for my fixture?
Go by part number, not by eye. TOTO publishes a specific gasket number per fixture, and THP4737 is the pipe adapter O-ring. Pull the model number off your toilet, flush valve, or faucet and confirm THP4737 is the gasket called out for it before ordering, since O-rings of similar size are not interchangeable across TOTO families.
2) Is the TOTO pipe adapter O-ring a one-piece seal or a kit with other hardware?
It is the O-ring seal only. The THP4737 is a single gasket, so any pipe adapter body, nuts, or mounting hardware have to be ordered separately as their own TOTO part numbers.
3) I manage several buildings with TOTO fixtures. Is this a part worth stocking?
Yes, if your TOTO fixtures use the pipe adapter that this O-ring seals. Gaskets like the THP4737 are the usual cause of a weep at a pipe adapter joint, and swapping the O-ring is a far shorter job than replacing the adapter. Buy by part number so what is on the shelf matches the fixtures you actually run.
