Cartridge was the right fit for my Pfister faucet.

This is exactly what I needed for my kitchen faucet that is about 10 years old (Ashfield line), model 5297YP. The parts breakdown says the cartridge is #974-074, and this is definitely the correct replacement (even though this new part has an extra 0 at the end). Also note that the color has changed from all white to black with a white bottom (as shown). The issue I had was the handle to the faucet sometimes would slowly drop down and turn on the water (at least a trickle). So I needed a new cartridge to fix the "loose" handle problem. In the photo, the old cartridge is on the left, and new one on the right. Changing this was super easy. First, make sure the water is off. The toughest part is finding the right size allen wrench (hex wrench) to remove the handle, but that is fairly easy (just put the wrench in the small hole on the handle and unscrew the screw attaching the handle to the end of the cartridge). Once the handle was off, I unscrewed by hand a cosmetic cap (in the photo see upper left round part) which exposed the locking device (brass, shown in the photo on the far right). That is removed with a large pair of pliers (just grip it "head on" on the two flat surfaces and unscrew it using pliers or pair of vice grips). Once that locking device is unscrewed, you just pull out the old cartridge and put in the new. On mine I DID need to use a screwdriver to remove the old seal (now a light blue on the new part, was red on the original part, again, see photo bottom left for the old red gasket that I had to gently scrape out of the internal workings of the faucet). Assembly is just the reverse - pop in the new cartridge (has two nipples that force the correct alignment), screw in the brass locking mechanism and tighten it (not too tight or you can damage the cartridge), screw on the outer cosmetic piece by hand, put the handle back on, use the hex wrench to tighten down the screw that holds the handle onto the cartridge, and you are done! In summary, I'm very happy! Thanks for reading :-)
