Apply Flux and Assemble Joint

What happens here

Using a small brush, apply a thin, even coat of 'No-Korode' regular paste flux to the freshly cleaned outside surface of the copper pipe and the inside surface of the copper male adapter. The flux helps to prevent oxidation during heating and allows the solder to flow smoothly into the joint. Push the male adapter onto the end of the copper pipe firmly. Use your work glove to wipe away any excess flux that squeezes out of the joint.

Goal: Apply flux and assemble the copper pipe and fitting
