Will it fit?
Fits
- Pfister single-handle pressure balancing tub and shower valves stamped 0X8, JX8, VB8 or JV8
- Valves that held either the one-piece 974-042 or an older two-piece set
Not compatible with
- Three-handle Pfister Marquis, Crown Imperial, Verve and Windsor valves (they use stems)
- Other multi-handle Pfister valves
- Pfister kitchen faucet cartridges
Is this your part?
Read the stamp on the valve body behind the trim. If it says 0X8, JX8, VB8 or JV8, this cartridge fits, whether what you pull out is one integrated unit or a two-piece set. The body accepts either.
When to replace it
The spout drips with the handle off, the shower turns cold when a toilet flushes or a washer fills, spikes hot without warning, never reaches full temperature, or the handle has gone stiff and unpredictable through its arc.

How to install it
Time: 15 to 30 minutes. Tools: Phillips screwdriver, Allen key for the handle set screw, Rubber grip glove for a stubborn sleeve.
- Shut the water to the valve.
- Pull the handle and escutcheon, then unscrew the threaded sleeve.
- Lift out the old cartridge or two-piece set.
- Grease the O-rings with the silicone packet. Petroleum grease cracks the rubber.
- Drop the new cartridge in at the same alignment as the old one.
- Refit the sleeve, escutcheon and handle, restore water and test.
Questions
My valve has a two-piece set. Does this replace both parts?
Yes. This single-piece cartridge does the work of both halves, so there is no second part to buy.
Is 974-5299 the same as 974-042?
Yes. 974-5299 is the current Pfister service number for the 974-042.
Does it fit my three-handle Pfister?
No. Three-handle Pfister valves use stems. FourHome sells the replacements for Pfister 910-374 hot and cold stem and 910-382 diverter stem for those.
