Prepare for Angle Stop Installation

What happens here

For the demonstration, a copper pipe is secured in a vise on a workbench. The presenter takes an angle stop valve, separates the compression nut and the brass ferrule from it, and suggests applying pipe dope around the threads of the valve for an improved seal, although he doesn't explicitly apply it in this segment. He then slides the compression nut onto the copper pipe, followed by the angle stop valve, ensuring the ferrule is correctly positioned within the valve's compression end. The assembly is left loosely fitted before tightening.

Goal: The presenter sets up a copper pipe in a vise and demonstrates how to assemble and loosely place an angle stop valve, compression nut, and ferrule onto the pipe, optionally suggesting pipe dope for a better seal.
