I am trying to remove an old faucet from my kitchen sink. I have come across a unique fitting I have never seen before. (See pictures) This T shaped fitting at the base of the faucet mount has 2 intakes for hot and cold and one output that goes to a separate sprayer. I can figure out how to remove this piece, it won't unthread. I have a feeling I need a special tool that may have come with the faucet, but this was already installed when I moved into the house. There is no manufacturer name on the faucet either. Ideally I would like to save this faucet and use it in my laundry room. Any advice?
Thanks,
Peter

That hose connection sure looks threaded to me. Any Allen Head screws or clips in the connection? Can you unhook the hose from it?
Any more details you can give me? There's no brand name anywhere? Back to you, Tom

I have unhooked as much of this assembley as I can, there is a nut just above this fitting which held the faucet tight to the sink, I have loosened it as much as possible but it can't go any further because it hits the T fitting. It looks like there is an oval shaped hole in the bottom output, I'm thinking there is a special tool that fits in this hole, but what I don't know what the tool is as there is no identification of what kind of faucet this is. I tried sliding a rod through the intakes on the side to gain some leverage, but as hard as I tried I couldn't loosen the upper fitting and didn't want to break it.

I know it may sound like a stupid question but you are turning it the correct direction aren't you ? Can you look up inside to see if you see any fasteners although that seems strange to me. GOOD LUCK, AC

Could that "hole" be a opening for a Allen Head screw?

Here is what I think.
