Mixer Balancing Cap stem assembly replace for Kohler model# GP77759 fit for Pressure Balance 1/2" Shower Valve and the K-304 valve Compatible for Rite-Temp shower valves.

I used Magic Lube and the dripping took a week or so to stop. I possibly used too much.

It was an easy fix for my leaking shower. My only problem was not took me so long to find the right part as the shower knob did not have any brand engraving. I just happened to see some numbers on the valve and searched the serial numbers on Amazon.

This a Knock off Chineese part and everything is just a little "off spec" and doesn't quite fit like the OE. Save your time and spend a couple dollars more and look for genuine and not "FOR KOHLER" on the description of the product, it bit me and that will not happen to me again!

I tried to fix my shower for a long time and couldn’t find the part to do it. It’s an older kohler part apparently and I would have had to order from the company. I saw this part on Amazon and it looked really similar to the part I needed and the price was much lower than the websites I was seeing so I gave it a try. FIXED!! No more leak! Finally!!!

I was unable to locate a genuine Kohler cap , so I purchased this aftermarket unit. First time installing the cap ,it leaked through the valve to the shower head. I removed it and removed the balancer as well and cleaned the ports and applied plumbers grease to all the o-rings and a tiny bit of silicone. It sealed tight second time around. So far so good....
