Install New Angle Stop (Repaired Pipe)

What happens here

With the copper pipe now properly prepared (cut, deburred, and clean), apply pipe dope to the threads of the new angle stop. Slide the compression nut and ferrule onto the pipe, then attach the valve. Hand-tighten the nut and then use the angle stop wrench to complete the tightening, ensuring the valve is stable and properly seated. Pay close attention to achieving a snug fit without over-tightening.

Goal: Install the final new compression angle stop onto the newly cut and deburred copper pipe section.
