Bathroom Faucet Cartridge Replacement – 2 Pcs Brass Quarter Turn 1/2" Thread 1.97" x 0.39" 20-Teeth Stem Kit – Faucet Valve Replacement Stops Leaks, Restores Flow for Kitchen, Shower, Sink Repair

Went to Ace Hardware and Home Depot and a local hardware store. None had a cartridge that came close to what I needed. Finally chose to check Amazon. And it fits perfectly! Was able to fix the leaking faucet in my bathroom. I only needed the one for Cold tap. But since I came in a pack of Hot and Cold, decided to replace both! The price of both together beat the price of one that was being sold in the stores!! And people wonder why I buy everything on Amazon! Great product! Great value! And easy to install.

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.

The stem is shorter.But this does not matter much. The screw in the stem is different thread since they use different standard. If you can use provided screw you are fine. I have to find a longer screw that fits their thread to install, because my faucet used an adaptor to fit handle. It worked fine after installation. I have to use impact diver to remove the old cartridge. Maybe a slide effect that a cartridge lasted too long.

Fit perfectly, stopped by leaky bathroom faucet....thank u so much

We bought a bathroom faucet off Amazon a few years ago and unfortunately one of the cartridges started leaking, after removing it and searching for a comparable replacement, i found this fit the bill, easy to install, and no more leaking.

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 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.

These faucet inserts are not high quality, but they fit in my faucet, and they work. These replacements were the only ones I could find for my generic faucet from Home Depot. The bad news is that last about 2 years before starting to leak. The good news is that they are only around 7 bucks for the pair. I'm planning on doing a remodel of the my bathroom within the next year or two, so they will tide me over till then.
