ALITZ GP71969 Valve Mixer Kit for Kohler Showers

Restore smooth, leak-free operation to your Kohler Coralais single-handle tub/shower faucets or Sterling shower units with this OEM-style replacement valve mixer kit. Designed as a direct match for the GP71969-style mixer cap, this kit replaces worn internal components that often cause stiff handle movement, dripping, or inconsistent temperature control—common issues in older Kohler valve systems.

The kit features the square plastic stem required for compatibility with select Coralais and Sterling models, ensuring proper fit and function. Important: Before purchasing, verify your original part number (GP71969), stem shape, housing dimensions, and mounting profile match this replacement. This kit does not include the handle, trim, valve body, or pressure-balancing components—only the mixer assembly itself. As a third-party replacement, it’s not an OEM Kohler or Sterling part but is engineered to restore performance in compatible systems.
