Exactly the right part for my kitchen faucet, the same that my plumber used. I bought several for future use since the part does give out after a number of years.
This is the 4th cartridge I've had for this faucet in 8 years. None have lasted longer than 2 years but this one dripped from day one. I would NOT recommend it. I got a free one directly from Moen using the warranty service and it dripped the same way...about one drip every 60 seconds. Horrible product!
