That’s the under side of a kitchen sink faucet.Maybe I'm not looking properly but what is the orientation of this tube/pipe? Is it coming out horizontally from a wall or vertically from something over it? What at the 'cables' coming out? Can you see the other side? If so, what's there? The picture (to me) has no point of reference.
It’s a kitchen faucet. The larger threaded tube is the shank of the faucet and the water supplies along with the pull out sprayer hose extends through this shank.I dunno, if you blow that picture up and look really close, it looks like TWO threaded pieces. The outer piece is up against that 'brass' C thingy but if you look real close, it looks like there is a STEP down to the other threaded piece. I think I would remove those two screws and see if the outer piece will just unthread from the inner threaded piece; and I wouldn't touch those hoses/whatever until I got those two threaded pieces apart. And it looks like the black hose is inside a white collar tube; is this one of those sprayer hookups where you pull up the black hose to move the sprayer around? Maybe a description of what is on TOP of this assy would be in order?
