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

Did the job. Cost was the same with shipping as it was locally, but this way I didnt have to leave the house.

Excellent

Fixed my leak in the bathroom faucet and was super easy to install! It was actually cheaper here than at home depot

As others have said, can be extremely difficult to get the old cartridges out. Mine seemed like they were welded in place! I was afraid I might damage the sink by applying too much force to the wrench (faucet was moving in the sink). Here is what worked for me. 1. Disconnect the faucet from the supply hoses and pop-up drain, you will probably need a basin wrench to do this. 2. Remove the faucet from the sink. 3. Wrap plenty of duct tape around the thread pipes at bottom of faucet (to protect threads from damage). 4. Put the faucet in a vice in a work bench, held in place by the pipes wrapped in duct tape. 4. Try again with the wrench. Took a lot of force, but even without any penetrating oil both cartridges released and came out. New ones are a doddle to put in and dont need much tightening.

Perfect fit and easy install with appropriate socket wrench.

It came in a original Kohler replacement package. No issue installing it and work just fine.

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.

Perfect replacement. Works great!

Easy to install and works great.

Replaced a number of leaky valves. Good product
