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

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.

Great quality. Fixed the leak. Note, if you are the original owner of the faucet, these cartridges are probably covered under Kohler warranty. I realized this too late.

Pefectly fits as replacement valve for Kohler shower.....however one must make sure to choose the right part number for cold and warm.....

Easy replacement except there were no instructions. Its a good thing it is intuitive.

Faucet works like new now. installed both hot and cold sides in 10 minutes.

They arrived very quickly. They fit perfectly and it was an easy installation. The drip from the faucet stopped immediately.

Perfect replacement for my old Kohler faucet. No more drips!

Works great.
