TOTO 9BU112E-A – Frequently Asked Questions
1) Is TOTO 9BU112E-A the tank-to-bowl gasket or the flush valve seal?
9BU112E-A is TOTO's flush tower gasket, the tank-to-bowl gasket that seals between the tank and the bowl. It's the rubber seal itself, not the flush tower or the flush valve assembly, so if the tower body is cracked or the canister is failing you need the tower, not this gasket.
2) My TOTO toilet is leaking between the tank and the bowl. Is a gasket what I need?
Water weeping from the joint where the tank meets the bowl is the classic sign the tank-to-bowl gasket has gone hard or taken a set. The TOTO 9BU112E-A flush tower gasket is the replacement seal for that joint. Shut the supply, flush dry, unbolt the tank, swap the gasket, and reset the tank. If the drip is instead coming from around the tank bolts themselves, that's the bolt washers, a separate part.
3) Will the TOTO 9BU112E-A gasket fit any TOTO toilet?
No. TOTO uses several tank-to-bowl gasket profiles across its flush tower and canister designs, and 9BU112E-A is one specific part. Match it to the gasket your tank actually calls for by TOTO part number rather than by tank model guesswork, since a gasket of the wrong profile will seal poorly at the tank bolts.
4) Is TOTO part 9BU112E-A a genuine TOTO replacement part?
Yes, 9BU112E-A is TOTO's own part number for the flush tower gasket, sold as a genuine TOTO replacement part rather than a universal aftermarket seal. For maintenance staff standardizing on TOTO fixtures, ordering by that MPN is what gets the correct seal for the tower it belongs to.
5) Does the TOTO flush tower gasket come with tank bolts or washers?
9BU112E-A is the gasket on its own, a single replacement part. Tank bolts, brass washers, and nuts are ordered separately, so if you're pulling a tank that's been in service for years it's worth having a bolt set on hand too, since old bolts often won't come off clean.
6) Do I have to replace the whole toilet tank if the tank-to-bowl seal is leaking?
Rarely. A leak at the tank-to-bowl joint is almost always the gasket, and the TOTO 9BU112E-A flush tower gasket replaces just that seal. Replacing the gasket is a tank-off job with hand tools, no plumbing rework and no new fixture. Only chase further if the porcelain itself is cracked at the joint.
