Reply to comment by sarxsvt in Replacing kitchen faucet and there’s this weird substance under mounting nuts. What do I do? by warsquiat

Thank you!! I just ended up cutting them off and am going to install the new sink in tomorrow. Here’s the photos in case you can identify the mystery substance

Yeah, that is just plumbers putty (sometimes people will use it to seal the faucet to sink if they don't have the gasket) you can use a putty knife or razor blade to scrape the rest off of the sink

Yeah that’s what I ended up doing. Have the sink installed and wverything is fine, except a piece under the sink was totally corroded and broke off so now there’s a leak. Here’s the piece and where it goes. Do you have any idea about how I could go about sealing this?

Looks like you need a new "branch wye" (that's the name of the piece of pipe with the little arm on it that the hose is connected to). It connects to the "basket strainer" (the piece that goes through the sink opening) using a "slip joint" nut and washer. You should be able to take it off with a pair of adjustable pliers. Make sure you have a new "flange washer" for the connection between the "branch wye" and "basket strainer". If you take this photo to a hardware store or plumbing supplier, they should be able to outfit you with the proper parts.
