TOTO THU9191 – Frequently Asked Questions
1) What is TOTO part number THU9191?
THU9191 is a TOTO plumbing supply hose part, sold under the washer and O-ring designation for a TOTO water supply hose. Order it by the MPN THU9191 so you get the TOTO original rather than a generic seal.
2) Should I use a TOTO THU9191 seal or replace the whole supply hose?
If the hose body and braid are sound and the leak is at the connection, the THU9191 washer and O-ring set is the repair part. If the hose itself is kinked, corroded, or weeping along its length, replace the supply hose assembly instead; a new seal will not fix a failing hose.
3) Is THU9191 a TOTO-specific part or will any washer work?
It is a TOTO service part. Seal and washer dimensions on TOTO supply connections are matched to the fitting, so a hardware-store washer often seats unevenly and weeps. For a maintenance crew stocking TOTO fixtures across a building, keeping the TOTO THU9191 on the shelf is the way to keep the repair consistent across openings.
