How to use copper pipe compression fittings?

Copper pipe compression fittings are a reliable and effective way to join two pieces of copper piping. A compression fitting works by using threaded nuts and a compression ring, which helps to create a tight seal between the two pipes. This fitting type is ideal for plumbing applications, as it provides excellent durability and longevity. In this article, we’ll give you an overview of how to use copper pipe compression fittings so that you can make sure your plumbing projects are completed correctly.

Step 1: Measure the Pipes

The first step in using copper pipe compression fittings is to measure the pipes that need to be connected. Ensure you get an accurate measurement, as even minor errors can cause problems with the connection. Please consider any bends or angles in the pipes when measuring them, as these will also affect the final connection.

Step 2: Prepare the Fitting

Once you have measured the pipes, it’s time to prepare the fitting itself. Start by sliding one end of the fitting onto one of the pipes and then threading on one of the nuts until it’s tight against the end of the pipe. Next, slide on a compression ring before repeating this process with the other nut and pipe. Ensure that both nuts are firmly tightened against each pipe before going to Step 3.

Step 3: Connecting The Pipes With The Fitting

Now that you have both nuts secured against each pipe, it’s time to connect them with your fitting. Thread both nuts onto either side of your fitting until they’re securely fastened. Once this is done, your connection should be complete! However, if there’s any play or movement in your relationship, you may need to tighten up your nuts further for a better seal – be careful not to over-tighten them, as this could damage your pipes or lead to leaks later down the line.


Using copper pipe compression fittings is a simple yet reliable way of joining two pieces of copper piping together quickly and securely. By following these steps carefully, you should be able to join your pipes confidently – remember not to overtighten any components during installation! With correct usage, these fittings should provide years of trouble-free service for all plumbing projects, large or small – happy connecting!
