Kohler K-GP77006-RP GP77006-rp Ceramic Valve, One Size, Rough Plate

Product was as described and worked well.

I fixed my leaking faucet myself and saved $$

These worked perfectly in my dripping Kohler whirlpool tub faucet. The biggest challenge was figuring out which size to buy and then removing the old one. Over the course of about a week, I tried spraying the old one with WD40 and then PB Blaster every day or two. Neither worked well enough to loosen the bolt. A friend had a much larger ratchet than mine which I borrowed and it did the trick — probably because I could get a lot more leverage on the longer handle. Next time I would try even insterting the end of my smaller ratchet into a pipe to lengthen it. In this photo you can see my much smaller ratchet next to the granddaddy sized one that I borrowed that did the trick.

One of the earlier reviews stated that these did not look the same as the originals and were not made by Kohler. These are - and they come with a spline adaptor so dont bother buying them (You can also likely remove them from the old cartridges. If you have difficulty in removing the old part - put some vinegar on it and let it set for a few minutes - a suggestion I received from Kohlers customer service department (Who did an outstanding job helping me). You probably wont need vinegar unless you have hard water - the water here is so hard you have wear a hardhat when it rains. Once the corrosion is dissolved, it is easily removed and the new one is installed. (I recommend using pipe dope or teflon tape so that if you have to remove it in the future it will be easier to do so.

Kohler told me they no longer carry these ceramic valves for the Revival Widespread Faucet (K-16102-4A) so they sent their Ultraglide replacement kits (under warranty) 1131482 (cold) and 1131481 (hot) but to install those requires going under the sink to remove/replace the old parts including the brass valve bodies and hoses. Much simpler to just unscrew the old ceramic valve and put a new one in! So, I found this here, ordered it and installed without issue. And, contrary to what others have reported, the part I received was genuine Kohler with a brass body (not zinc plated). Simple install and no more leaks!

Exactly the right part I needed. Quick too.
