Counter tip: Pfister made more than one 0X8 cartridge over the years (974-0420, 974-5319, 974-5299). Pull yours and compare before ordering, or send us a photo.
Replacing the whole valve
If the valve body is damaged, the 0X8 rough-in valve comes in several connection types, such as universal (MIP) and PEX crimp, with or without stops. Match the connection to your pipe. Check our shower valve guide for the basics.
