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

Genuine kohler part, went in very easily (a lot easier than taking out the old one!). No complaints with the part itself - seems to be the same quality as the piece that I removed. However, I have the Bancroft monoblock 2 handle kohler faucet (model #K-10579-4-CP) and this part is actually for the hot water side. Pay attention to the clockwise vs counter-clockwise turn for your particular faucet to make sure you dont make the same mistake I did!

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.

Product as described. Harder to install than expected but thats based on the design and not the replacement part.

Cant comment on other peoples experiences, but I received a genuine Kohler part in sealed packaging. Fits and works perfectly!

Works great. If you have trouble getting the handle off the faucet valve then wrap around 2 feet of duct tape the chrome handle base and use a channel lock pliers to twist them off. This works on my Koehler faucet.

Excellent

Fixed my sink exact piece I needed

These are no fun to change if they are stuck together. They fit the faucet and work fine . I had to completely remove the faucet / mount in a soft jawed vice /penetrating oil/ propane torch. Get the picture . If yours dont come apart easily , you may save time and frustration by purchasing a new faucet.

Works perfectly and its a genuine Kohler replacement part.

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