Final answer:

To properly connect two ACR tubes of the same size that have been swaged, the process called sweating is used. This involves heating the tubes and using solder to join them, ensuring a hermetic seal for durability in the refrigeration system.

Step-by-step explanation:

A proper connection of an ACR (Air Conditioning and Refrigeration) tube to another ACR tube of the same size that has been swaged involves sweating the tubes together with solder.

Sweating is a process of soldering in which the two copper tubes are heated and then joined by using a filler material, like solder, which is melted and drawn into the joint through capillary action. Critical steps in this process include proper tube preparation, application of a flux to prevent oxidation, alignment of the tubes for a uniform joint, heating the joint with a torch, and running the filler material into the joint to ensure a hermetic seal.

This process requires cleanliness and attention to detail to ensure a leak-free connection that will be durable and reliable in air conditioning and refrigeration systems. Tools typically required for this task include a swaging tool, a torch, solder, a wire brush, and flux.
