About This Product
This 2-pack repair kit is a lifesaver if your Kohler shower's acting up.

It includes the GP876851 mixer cap and pressure balancing unit, plus GP800820 and GP77759 components – all compatible with K-304 and K-11748 valve platforms.
The kit lets you fix leaks, temperature fluctuations, and pressure issues without tearing out the whole shower.

Made with water-resistant plastic and solid brass, it's built to last and resist wear.

Before you install, clean out any debris with sandpaper, lubricate the O-rings, and make sure they sit flat – no twisting needed.
This covers both the mixer cap and balancing unit, so you get a complete fix.
Easy, effective, and way cheaper than a full valve replacement.
