As someone who has worked with plumbing systems for many years, I can attest to the fact that 3/4 compression fitting copper is an essential component in any plumbing project. These fittings are specifically designed to connect two pieces of copper piping together, creating a secure and leak-free joint. Here are a few reasons why these fittings are necessary:

The fitting can easily be removed and replaced without damaging the piping, making it a great option for future repairs or modifications.
