Why risk scratching the finish when a strap wrench can be used instead of pliers? Harborfreight has them very cheap.

FWIW, the inside of my Delta single-handle kitchen faucet did not look like this AT ALL. There were no little O-rings or springs, just a plastic cartridge with no replaceable parts. I found a replacement cartridge at a plumbing store (the big box stores did not carry it) for 30-some dollars, but the guy there told me that Delta has a lifetime warranty, and I should just call Delta for a free replacement. So if you have a leaky Delta faucet, you might just want to try getting a replacement cartridge instead of figuring out whether your faucet uses springs and O-rings or not.
