Moen4000 Single Handle Replacement Cartridge

Good instructions and perfect fit. 15 minutes for a faucet to work like new for around $10. The most difficult part was making sure I found the correct cartridge before ordering.

OK, apparently this cartridge is not as popular as the 1255, as it was nowhere to be found at big- or small-box HW stores in San Diego. Nonetheless, Amazon came through in less than a day. The Moen product comes with an instruction sheet in the box, which has the necessary tricks to get the thing changed out. A 3/32” Allen wrench, small, is crucial to get the handle set screw loose. Also, the little red o-ring (Mickey Mouse shape) may remain in the faucet body, so a small seal pick, such as the OTC Tools 7312 https://www.amazon.com/dp/B000P70QPW is a handy way to extract the seal, if needed. The whole thing is a really quick fix with the 4000 cartridge. And no drips now. Yay!

My faucet started to leak right at the handle. It was slow over time but recently you could tell it was ready to call it quits. It's super easy to access with some allen wrenches, pops right in and you are back in business.

I like to leave reviews but some things, honestly it is hard to figure out what to say. This cartridge fit in my faucet easily, quickly and seemed to be a great replacement for what was in there. That is what I needed and what I got, so all needs satisfied.What I will add is that I ordered this very late in the day, I believe late Tuesday night, and yet it still arrived 2 days later on Thursday. I was expecting it to arrive on Friday. So, I thought that was a nice and unexpected bonus.

Very good! fit my KEROX kitchen faucet. good replacement.

Our bath faucet began to leak. My husband pulled out the original cartridge and the O rings cannot be replaced so we ordered this cartridge. It fit like the OEM one and the faucet does not leak. Fast shipping!

Its a genuine Moen. Install it and call it a day. NOTE: There is an issue with the kitchen sink faucet that this cartridge goes in. The 2 large thin "gaskets" at the top and bottom of the spout can go bad. I still haven't figured out how.. as they look perfectly fine when this happens, but I replace those hard thin gaskets with the equivalent sized Orings, with a generous coating of Radiator Specialty Plumbers Grease, and the faucet no longer leaks around the spout base. If this is your issue, this cartridge won't help you. This cartridge fixes a faucet dripping out the aerator at the end of the spout, NOT at the base of the spout.

Arrived on time and fits and worked perfect. Though not mentioned in the description or on the part, if your faucet uses Kerox K35A cartridge, this is perfect replacement part.Great price too!
