TOTO 9BU109E-A – Frequently Asked Questions
1) What is the TOTO 9BU109E-A gasket used for?
The 9BU109E-A is TOTO's tank to bowl seal gasket, the rubber seal that sits between the tank and the bowl on a two piece toilet and keeps water from weeping out at that joint. It's a replacement part, so it's what you order when the old gasket has hardened or a tank is being pulled and reset rather than something you buy with a new toilet.
2) Is the TOTO 9BU109E-A the same part as the DFV seal gasket on a TOTO toilet?
Same part. TOTO catalogues this gasket as the DFV seal gasket under part number 9BU109E-A, and it is ordered by that number. If a parts diagram or a service call names the DFV seal gasket, 9BU109E-A is the number to put on the order.
3) Do I need to order anything else when I replace a tank to bowl gasket?
The 9BU109E-A covers the seal only. Tank to bowl bolts, washers and nuts are separate parts, and on a tank that has been sitting they're usually corroded enough that you want fresh ones in hand before you break the joint. Order the bolt set for your specific TOTO model alongside the gasket so you aren't making a second trip.
4) Does the TOTO 9BU109E-A gasket come in more than one size or version?
One version only. The gasket ships as a single part, 9BU109E-A, with no size, color or material options to pick from, so there's nothing to specify beyond the part number itself.
5) Will a generic tank to bowl gasket from the hardware store work on my TOTO instead of the 9BU109E-A?
TOTO tank to bowl gaskets are model specific in shape and thickness, and the flush valve shank they seat around is not the same across brands. The 9BU109E-A is the TOTO part matched to the DFV valve. If you want the joint to seal on the first try rather than chasing a slow weep, order the TOTO number.
