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

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

Fit fine but the old one was made with Brass and copper. This appears to be chromed steel or maybe stainless. I replaced the hard to turn unit with this, then soaked the old unit in vinegar overnight before disassembling, soaking parts in vinegar again to get the calcium out of the insides. Lubed with pool lube and re-assembled. Ill keep it on-hand to replace the next one that gets too difficult to turn. To rebuild, remove the clip and bow-tie stopper from the top, pull the washer off the bottom, and push the top down through the base. But unless you have extra time to do this, its cheap enough to just buy a new one next time. Use Teflon tape when replacing to make it much easier to take out next time. As others have noted, it really doesnt matter which side you buy. The only difference between hot and cold is a little bow-tie stopper on the top held in place with a clip. If you want to switch it, pull the clip and rotate the stopper 90 degrees. Pictures are of the old one rebuilt to show the clip and stopper.

Installed and works great

Better quality than the original.

Perfect replacement. Works great!

A 25 year old valve started dripping and this was an easy to find replacement that works perfectly. There was some problem doing the replacement but it had nothing to do with the valve. A spark plug socket that fits the valve solved the problem.

OeM fit

Did just what I needed it to do, and easy to install.

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

Perfect fit and easy install with appropriate socket wrench.
