American Standard 954040-0070A – Frequently Asked Questions
1) What is American Standard part 954040-0070A?
It's a thermostatic valve cartridge for American Standard bath and shower faucets, sold as a repair part. The cartridge is the temperature-regulating core of a thermostatic tub/shower valve, so this is the part you order when the valve body stays in the wall and only the mixing element is replaced. The orderable part number is 954040-0070A, supplied with no finish since it sits behind the trim.
2) Is a thermostatic cartridge the same thing as a pressure balance cartridge for a shower valve?
No. A thermostatic cartridge, which is what the American Standard 954040 is, senses outlet water temperature and modulates hot and cold to hold the setpoint. A pressure balance cartridge only equalizes hot and cold pressure to prevent scald swings when another fixture is used, and it does not hold a temperature setting. The two are not interchangeable in the same valve body, so match the cartridge to the valve you actually have in the wall before ordering.
3) Does the 954040 thermostatic cartridge come in a finish to match my shower trim?
No, and it doesn't need to. The 954040-0070A ships with no finish because the cartridge installs inside the valve body behind the escutcheon, where nothing is visible. If you also need the visible parts to match, that's a separate trim kit order, not this part.
4) I manage apartments with American Standard tub and shower valves that won't hold temperature. Is replacing the cartridge the right fix?
If the valves are thermostatic American Standard units, yes, that is the standard repair. Temperature drift, creeping hot, or a valve that no longer responds to the handle setting is almost always the mixing cartridge rather than the valve body or the trim. Part 954040-0070A is the cartridge-only repair part, so you keep the rough-in valve and the finished wall intact. For a fleet of identical showers, standardizing on the one cartridge number keeps the maintenance stock simple.
5) Does the 954040 cartridge include the trim, handle, or escutcheon?
No. This is the thermostatic cartridge only, catalogued as a repair part. Handles, temperature limit stops on the trim, escutcheon plates, and the valve body are all separate. If a handle broke along with the temperature control, plan on ordering the trim components as well.
6) How big is the American Standard 954040 cartridge, and will it clear a tight rough-in opening?
Packaged dimensions are 12.913 x 7.5 x 1 inches at 0.73 lb. Those are the shipped figures rather than the body diameter, so the useful takeaway is that it's a slim, light part; clearance in the wall is set by your existing valve body, since the cartridge only has to seat back into the bore the old one came out of.
7) Can I use the American Standard 954040 thermostatic cartridge in a commercial building, or is it residential only?
It's a repair part for American Standard bath and shower faucets and is used wherever those valves are installed, residential or commercial. What actually governs the application is the valve body already in the wall, not the cartridge; if the existing thermostatic valve was approved for the installation, the replacement cartridge keeps that valve working as designed.
