Hi - I need to replace a Moen Tub cartridge.  I removed it and took it to the hardware store.  I was first disappointed, then, pleased, and now confused. The fellow at the hardware store asked why I didn't phone Moen.  He said they didn't sell the replacement part. (disappointment). He then reached under the counter and pulled out a box of cartridges and tried to match it.  We found one that was close.  He said that they didn't sell the part , so I could have it for free.  (pleased). When I got it home, the parts had some items that were shaped differently but that appeared cosmetic.  The one main difference is that the new part did not have an o-ring at the back.  I took the o- ring off the old part but noticed that the groove on the new part is way too thin for that o-ring. Here's a picture of the part that I removed: http://www.faucetdoctorsuperstore.com/Admin/photos/thumb/Moen%201222%... Here's a picture of the replacement part: https://www.plumbersstock.com/images/products/large/00247672.jpg Notice the replacement part: -has no o-ring -it has round rubber pads (as opposed to square) -has round orifices as opposed to diamond shaped on the rubber part -has extra orifices at the front and back in the white plastic part From what I can see on the internet, there is only one replacement part (1222) and both of the above are designated as part 1222. Has anybody had experience with these and knows if I need a different part or some sort of kit to make this new one fit (specifically that o- ring). Thanks

Thanks I haven’t seen one of those in a long time but if I remember correctly it works without an o ring.

Maybe because Moen will give you a new one free, ya think?        http://www.moen.com/consumer-support/warranty nogo from the warranty page: Proof of purchase (original sales receipt) from the original consumer purchaser must accompany all warranty claims

I haven’t seen one of those in a long time but if I remember correctly it works without an o ring. I'll give it a try.  I guess the back of the enclosure is sealed so maybe it doesn't matter. Thanks.

See what happens. Worse thay will say is no. Heck, ShopVac sent me a new motor once without me sending anything to them. Nope, it wasn't registered.
