TOTO THU6283 – Frequently Asked Questions
1) Is TOTO THU6283 the right part if my toilet handle is leaking at the tank?
That is the situation this part is made for. The THU6283 supplies the case unit gasket that seals where the lever assembly passes through, plus the lever cover. If the leak is coming from the seal around the flush lever case, this is the replacement. If the handle itself is broken or the arm is snapped, you need the complete handle assembly instead.
2) How do I make sure a TOTO flush lever gasket kit matches my toilet?
Match by TOTO part number, not by model appearance. TOTO publishes a specific THU service number for each trip lever and case unit, and the gaskets are not interchangeable across families. Pull the TOTO model number stamped inside the tank or on the bowl and confirm THU6283 is the lever part called out for it before you order.
3) Can I order the TOTO THU6283 in a different finish?
No. THU6283 is a single part number with no finish or size choices behind it. You order the one part as TOTO builds it.
4) Is this a plumbing repair part or a bathroom accessory?
It is a plumbing repair component for a toilet flush lever, a gasket and lever cover set rather than a decorative bath accessory. Property managers stocking spares for TOTO fixtures generally carry it alongside flappers and fill valves.
