Restore Stable, Safe Temperatures

The TB-2 cartridge maintains set temperature as pressures fluctuate, helping eliminate sudden hot/cold swings. After installation you can set the integrated high-temperature limit stop to meet local code and reduce scald risk�Hansgrohe specifies a maximum shower outlet of 120 �F (112 �F in MA).

Designed for ThermoBalance II Roughs

This is the factory cartridge for ThermoBalance II systems and services rough-in valves 06623000 (no stops) and 06627000 (with stops). It is not compatible with Hansgrohe iBox Universal Plus or other series; ThermoBalance I and III use different cartridges (TB-1 88585000 / TB-3 88500000). Verify your rough before ordering.

Quick, Guided Replacement

Hansgrohe�s service booklet shows the TB-2 change-out step by step. A key callout: remove the old blue sealing gasket from the rough body before installing the new cartridge to avoid damage, then tighten the screws in the numbered sequence.

Built for Two-Function Showers

ThermoBalance II valves supply two separate outlets and are rated up to ~8 GPM at ~44�45 psi, giving plenty of capacity for a showerhead plus handshower. Per Hansgrohe, do not use this valve with a diverter tub spout. The TB-2 restores the valve�s original thermostatic performance.

Confidence in Code & Compliance

While the cartridge itself is a service part, the complete ThermoBalance II valve assembly carries third-party compliance�ASME A112.18.1/CSA B125.1, IAPMO listing, and UL listed�when installed per instructions. Using genuine TB-2 parts helps keep that compliance path intact.

Backed by Hansgrohe Warranty

Hansgrohe backs its consumer installations with a Limited Lifetime warranty (1-year for commercial), available on purchases from authorized sellers. The service page also provides tech tips and support if you need a hand during replacement.
