Review: Perfect fit! - Saved me some much time and money. Worked perfectly! Review: Fits and it's Brass - I measured before I purchased and it fits perfectly except that the spline is too long. So the handle wobbles. NO PROBLEM! It's brass and brass is great because it doesn't burr over - it cuts clean. So a few minutes on the sander and chamfer it by hand with a drill and the screw slides in no problem. Couldn't be happier! The screws are a bit skinny but the ones I took out fit and are better quality (1950's?) My bathroom faucet is very old but the quality is outstanding and I didn't want to replace it so this was a phenomenal fix! ## Features - Suitable for replacing basin/sink Faucets with 20 teeth on the stem and 53mm overall. - 1/2" Basin size cartridge with threaded collar; M4 solid screws provided. - 20 tooth stem measures 7.6mm diameter and 12mm length.

All I can tell you is that there are 2 different diameter stems-these are 1/2 inch diameter for sinks and the other looks exactly the same but is 3/4 diameter for tub faucets. **Q: Is this equivalent to the paini asme a112.18.1upc ansi nsf61** A: I am not so sure. But I think you are right. Why Not Have a Try? **Q: anybody ever find a handle anywhere that fits this stem? seems strange one is not offered of any kind. Can’t find anything on google either** A: A handle? All I can tell you is that these cartridges work with Altman's and California bathroom faucets... **Q: will it fit a Bridgewater faucets, it does look identical to the Bridgewater cartridge** A: If they don't work , you can send them back..I have a different make of faucet, and only got the cartridges right on the third try.... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect fit! *by B***N on 20 July 2026* Saved me some much time and money.
