enter image description hereThis is a 4 year old faucet, and it has a nut/extension that I have not seen before. The tip is plastic. I checked with local HD, and they did not have an answer either. I appreciate your help. enter image description here

  • I believe those are caps to protect the lines. Pull them off to see what you have underneath.

  • You may need to twist them off rather than pull them off, if they're threaded... But, yeah, removing the black pieces looks like the first step.

  • @Ruskes: Hot and cold in, separate spray head out, hence three tubes. I could always be wrong, but that looks like the underside of a kitchen faucet to me. And the OP says it's a faucet. Why do you think otherwise?

    It appears they have to be tightened from the other side. However you can try to grip the threaded stubs with pilers and turn them at a risk of damaging the threads and having more issues later.

    Thank you All. Yes, it was the other side. I removed the faucet, and it was right there. For the record, this is a Kraus faucet, and I followed the Step 2, and Step 1 of this video. youtube.com/watch?v=2pfeofClXcA
