How to replace the water pipe that goes to flush tank

[irainesan]

I need to install a bidet toilet seat. My water supply line is a pull to close type. I have the following questions. Any ideas will be greatly appreciated.

(1) Please refer to the red circle in the first picture. How do I remove this end that connects to the water supply line? When I turn this end counter-clockwise with a wrench, it simply keeps turning but does not unscrew.
(2) After removing the part mentioned above, how do I connect the screw nut shown in the green circle in the second picture?. The parts shown in the second picture came with the bidet.

TIA

That valve you have is not designed to just remove the hose. You will have to remove that entire valve and replace it with a valve which allows a threaded supply line.

Yup change it out. They are junk.
