TOTO 9BU4005 – Frequently Asked Questions
1) Is the TOTO 9BU4005 O-ring for a faucet or for a toilet or flush valve?
It is a faucet part. The 9BU4005 O-ring is catalogued for residential faucet use, so it is not the right seal for a toilet fill valve, flushometer, or tank-to-bowl connection. For those, order the seal specified for that fixture instead.
2) How do I know the 9BU4005 O-ring is the correct seal for my TOTO faucet?
Match it by TOTO part number. O-rings in a faucet are sized to the specific spout, cartridge, or valve body they seal, and they are not interchangeable between models by eye. Pull your faucet's TOTO model number and confirm 9BU4005 is the seal called out in that model's parts breakdown before ordering.
3) What is TOTO part 9BU4005?
9BU4005 is a replacement O-ring for TOTO residential faucets. It is a single-piece seal, ordered by that part number, used when a faucet is leaking or weeping at a seal point rather than needing a whole new cartridge or valve body.
4) Can a property manager stock TOTO 9BU4005 O-rings as a general repair item for multiple faucets?
Only for the TOTO faucet models that specify this part. Because 9BU4005 is a model-specific residential faucet O-ring rather than a generic size, stocking it makes sense when your buildings are standardized on the TOTO faucets that call for it. If the units carry a mix of faucet models, pull the part number for each model rather than buying one O-ring across the board.
