The part I needed appears to be no longer available. However, I found it at Chicago Faucet Shoppe and it shipped the next day! Highly recommend!

I'm giving it a five star, due to the nozzle only purchase with Chicago Faucet was seamless again. great price, communication, ease of online purchase. I'm very disappointed with my Elkay faucet. I've replaced the head several times and it's only four years old. I did not purchase the faucet from Chicago. I'm glad I've located them for replacement parts.
