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

Used this to fix two pre-2011 Kohler sinks. Worked great.

Fits great a hair 1/4 inche short put a washer to lift it.

Perfect replacement. Works great!

Drop in replacement of original value.

Picture looks like it is silver plated but it is brass. Cold side. Works well.

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

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.

Works perfectly in our shower valves. Just remember that Kohler has different valves with unique part numbers for right and left.

Excellent

Genuine Kohler valve at Costco price. Perfect.
