TOTO THP4137 – Frequently Asked Questions
1) What are the dimensions of the TOTO THP4137 gasket?
The THP4137 is a ring gasket with an outside diameter of 18.5, an inside diameter of 12.5, and a height of 1.5, as TOTO publishes the figures. Match those three numbers against the seat or spout opening you are sealing before you order, since a gasket that is oversized on the ID will weep.
2) Is TOTO THP4137 a whole faucet aerator or just the seal?
THP4137 is TOTO's aerator kit part number, and what it supplies is the gasket, the ring seal that sits behind the aerator. If your complaint is a drip or seep around the aerator face, this is the piece. If the aerator screen itself is clogged or the threads are damaged, you need the full aerator assembly for that faucet model instead.
3) How do I make sure the THP4137 gasket is the right one for my TOTO faucet?
Order by the TOTO part number. THP4137 is a model-specific service part, so the way to confirm fit is to look up your faucet's TOTO model number and check that THP4137 is the gasket called out for it. If you are working from the old part, compare it to the published 18.5 OD, 12.5 ID and 1.5 height before installing.
4) Should a property manager stock the THP4137 gasket as a spare?
It is worth keeping a few on the shelf if your units run TOTO faucets that call out THP4137. Gaskets are the part that fails first on a lavatory faucet, they cost a fraction of a service call, and swapping one is a hand-tight job with no tools beyond an aerator key. Confirm the faucet models across your buildings use this same part number so one bin covers the fleet.
