Genuine Price-Pfister Faucet Cartridge and a Great Value
This is a genuine Price-Pfister faucet cartridge, complete with seal rings and instructions. The instructions were easy to follow. I installed this cartridge to fix a dripping cold-water faucet, but it didn't stop the drip. The cause of the drip is probably the faucet seat, which is a separate piece. I reinstalled the original cartridge but added the small blue seal ring from the new one, which was not described in the instructions but fit inside the original seal ring at the bottom of the cartridge. This stopped the drip and allowed full function of the faucet, although with slightly more resistance when turning the handle. I'm retaining the new cartridge in case another faucet needs to have the cartridge replaced. This is obviously a great product, and identical in form and function to the original.
