TOTO 6BU4055 – Frequently Asked Questions
1) What is the TOTO 6BU4055 part used for?
The 6BU4055 is a TOTO thermostatic valve repair part, a thermo control stem/retainer nut used in shower and tub applications. It is a service component for a TOTO thermostatic mixing valve, not a complete valve or trim kit, so it is ordered when you are rebuilding or servicing an existing TOTO thermostatic valve.
2) Does the TOTO 6BU4055 come with the complete thermostatic valve body or trim?
No. 6BU4055 is sold as an individual thermostatic valve service part (the thermo control stem), so the valve body, cartridge assembly and handle trim are separate items. If you need the full valve, order the thermostatic valve itself rather than this component.
3) How do I order the right TOTO thermo control stem for my shower valve?
Order by the TOTO part number. This one is 6BU4055, and it is offered as a single configuration with no finish or size choices to specify. Because thermostatic stems are model specific, match the number against the parts breakdown for the TOTO valve you are servicing before you order.
4) Can I use the TOTO 6BU4055 stem in a pressure balance shower valve?
No. It is a thermostatic valve component, so it belongs in a TOTO thermostatic mixing valve. A pressure balance valve uses a different internal assembly and this stem will not serve as a substitute.
