How to Join Copper Pipes without Solder – A Step-By-Step Guide

How to Join Copper Pipes without Solder

For any DIY enthusiast, soldering copper pipes is a skill that takes some time and effort to master. Fortunately, there are other methods for joining copper pipes that don’t require soldering. If you’re looking for an easier and faster way to join copper pipes without the need for a torch or solder, this blog post is for you! We’re about to walk through a step-by-step guide on how to join copper pipes without solder.

Step 1: Gather Your Materials

Before you begin joining your copper pipes without solder, make sure you have all the necessary materials. You will need two copper pipes of the same size and shape, a fitting such as an elbow joint or tee joint (depending on what type of connection you’re making), and pipe sealant tape. It’s also important to note that in order to join two different sizes of copper pipe together, you will need an adapter fitting.

Step 2: Clean Your Pipes

Before joining your pipes together without solder, it is very important to clean them thoroughly so they can form a tight seal. Start by wiping down the outside of the pipe with a cloth or paper towel until it is free from dust and debris. Then use sandpaper or steel wool to lightly sand away any oxidation from inside the pipe ends before joining them together with your fitting. This step should not be overlooked, as oxidation can prevent the sealant tape from forming a tight bond between the two surfaces.

Step 3: Apply Sealant Tape

Once your pipes are clean and ready to go, wrap each end of one of the pipes with sealant tape until it covers around 3/4 of its circumference. Make sure that each piece overlaps slightly at each side, so there are no gaps between them when both sides are joined together with your fitting. Repeat this process on the other pipe before moving on to Step 4.

Step 4: Join The Pipes Together With Your Fitting

Now; it’s time to put your pieces together! Carefully slide one end of one pipe into your fitting until it reaches its stop point, and then do the same with the other end of that same pipe into the second fitting until it reaches its stop point as well. Once both ends are secure in their respective fittings, give each piece a gentle twist back and forth while pushing inwards until they lock into place with each other securely. If done correctly, there should be no gap between either end of either pipe, and they should fit snugly against one another without any movement or wobbling when pressure is applied from each direction. And that’s all there is to it! You have now successfully joined two pieces of copper pipe without using solder!


Joining copper pipes doesn’t have to be difficult or tedious—you just need to know some tricks, like using sealant tape as an adhesive instead of relying solely on soldering techniques! Using this method requires fewer tools than traditional soldering methods and makes for quick connections between two pieces of piping—without having to worry about potentially damaging them by heating up components with a torch! Hopefully, this blog post has given you some insight into how easy joining two pieces of piping can be if done correctly with only basic tools like sealant tape! Happy plumbing!
