Kohler K-GP800820 pressure balance valve cartridge equipment

SKU CH-XH1Z-FMYBB

Pressure balance valve cartridge for shower valves with unfinished plastic construction

  • Pressure-balanced shower control from the K-GP800820 cartridge
  • Unfinished finish suits concealed valve installations
  • Plastic construction resists corrosion in wet environments
  • Designed for compatibility with Kohler shower valves
  • Genuine Kohler replacement part ensures reliable performance

Pressure Balance Cartridge

The Kohler K-GP800820 is a replacement pressure balance valve cartridge designed for shower valve maintenance. It fits compatible Kohler shower valve bodies to restore safe temperature regulation. Plumbers and facility managers use it to fix pressure-related temperature swings in commercial or residential installations. The unfinished plastic construction suits concealed rough-in applications.

Sustained Pressure Regulation

Under continuous flow the cartridge maintains a stable outlet temperature by automatically balancing hot and cold supply pressures. It reacts to supply fluctuations without manual readjustment, preventing scalding or thermal shock during extended use. The mechanism operates mechanically without external power, so performance remains consistent over long duty cycles. Internal seals resist wear from repeated pressure differentials.

Shower Valve Compatibility Limits

The cartridge only functions inside valve bodies engineered for Kohler pressure-balance geometry; it cannot convert a non-pressure-balance valve or fit competing brands. Installation requires access to the valve body through the trim opening, so closed-wall scenarios without access panels may prevent replacement. The unfinished finish indicates it is not an exposed trim component. Buyers needing thermostatic control or digital interface integration cannot meet those requirements with this pressure-balance cartridge.

Questions about this item

How much heat does the K-GP800820 cartridge generate during continuous shower use?

The plastic cartridge body does not generate measurable heat; water temperature is controlled by the pressure-balance mechanism inside the shower valve.

Which existing shower valve bodies accept the K-GP800820 cartridge for a direct swap?

It fits Kohler pressure-balance shower valves designed for this cartridge series; verify the valve trim and model before ordering.

Will the unfinished K-GP800820 cartridge work with my older Kohler brass valve body?

Yes, the unfinished plastic cartridge installs into compatible older Kohler pressure-balance valve bodies that use the same cartridge interface.
