Brass Bathroom Sink Faucet Valve Stem - 2Pcs Hot and Cold Ceramic Disc Stem Quarter Turn 1/2,50mm x 10mm Spline Length 20 Teeth Bathroom Faucet Cartridge Replacement - Bathroom Faucet Stem Replacement

I was skeptical but they worked well. I have been buying genuine kohler cartridges from Amazon (not third party) over the years but they keep failing maybe 2-3 years life time. I decided to try this one. Their size is smaller than the original Kohler but fit fine in the end. It has been two years and they still working well.

Installed on a 2007 Kohler Coralais Tub Faucet.Easy install with a little prep. You will need to save the stem adapters from your old valves to put on this one for the KOHLER CORALAIS FAUCET. And yes, as other reviews mention the worst part is removing the old valve. After reading other reviews, we prepared for removal problems on the 15 yr old valves by removing the handles and giving the old valves several soaks of PB Blaster beforehand throughout the day. We also used an 18" breaker bar with 5/8" socket for removal. Thankfully, they both popped loose without spinning. New valves went in easy but they do require a larger socket size(can't remember size but bigger than 5/8"). Also we used some silicone plumber's grease to install new valves to ease changeout next time. Don't overtighten new valves. Works perfectly.

In any repair, the only thing that succeeds is the CORRECT part. These replacement faucet cartridges were exactly correct. They are well made and very robust. Much better than the plastic replacements that were available at the big box store and less expensive to boot. Installation was easy and flawless. Nothing is better than having a repair project go according to plan with the right parts.

My husband found the resultsSatisfactory. It did stop the leak-- for how long ... we shall see.

The item seems to be make with good materials, but some of the measurements seem to be out of tolerance. The fluted stem top did not fit properly. One set of the threads on the body of the cartridge also did not fit well. The price was attractive, but it is deceiving. I suppose it is possible I got a cartridge that some slipped through quality control. Regardless, the item does not work for me.

I put 2 tiny washers under the hold-down screw for the handle because the grooved head is a little bit short.I ordered another set to prepare for the next time the calcium builds up to a leaking condition.

The metal is very soft, so it can be easily damaged. And the edges had a fair number of burrs, so work gloves are recommended to prevent cuts.
