Llave para cocina de una manija en cromado

I already have a sprayer, just want to replace the faucet. Can you attach the existing sprayer to this faucet? Do I need to buy a part to do this? If so, what parts do I need?

After a few years of good service, the gasket wore down, and I had to remove the faucet to prevent water damage below, all is in great condition, except the gasket is in bad shape, and cracked at one end. looked for a replacement part, but did not find. Can this be purchased individually?

I notice the copper water supply tubes are much skinnier than your previous models -- like 1/4" (or even smaller diameter) -- the screw fitting will fit fine, but why did Delta reduce the size of the copper tubes? I was wondering if it was to reduce water pressure to be easier on the faucet. Will I notice any difference in water flow out of this faucet? I hesitate using one with the plastic pipes although I just talked to a property manager friend of mine and he says they are fabulous -- easy to install and he has even re-used them after remodeling. Just wondered about this one with the skinny copper inlet tubes, though.
