I am not sure what you are referring to; the needle valve is already one unit from what I can see in your (blurry) photograph.

A bench vise is the easiest way to do it. You can probably do it without one, but it will be harder.

You can do this too, but I would prefer to remove the needle valve that is currently on there for a cleaner look in the end.
