Copper Pipe Transformers: What is Compression Fitting and Why You Need It

Compression fittings are a type of pipe fitting used to connect copper pipes without the need for soldering or welding. They consist of a body, a nut, and a ferrule. The body is the main part of the fitting and has a threaded end that connects to the copper pipe. The nut is tightened onto the body, which compresses the ferrule and creates a seal between the pipe and the fitting.

Benefits of Compression Fittings for Copper Pipe

Compression fittings offer several benefits over other types of pipe fittings, including:

• Ease of installation: Compression fittings can be installed quickly and easily, even by DIYers.
• No special tools required: All you need to install compression fittings is a wrench or pliers.
• Reusable: Compression fittings can be reused multiple times, making them a cost-effective option.
• Versatile: Compression fittings can be used to connect copper pipes of different sizes and types.
• Leak-proof: When properly installed, compression fittings create a leak-proof seal.

Choosing the Right Compression Fitting for Copper Pipe

When choosing a compression fitting for copper pipe, there are a few factors to consider:

• Pipe size: Choose a fitting that is the same size as the copper pipe you are connecting.
• Type of pipe: There are different types of compression fittings available for different types of copper pipe, such as soft copper, hard copper, and PEX.
• Material: Compression fittings are typically made from brass or plastic. Brass fittings are more durable and corrosion-resistant, but plastic fittings are less expensive.
• Brand: There are many different brands of compression fittings available. Choose a brand that is reputable and offers a warranty.

How to Install Compression Fittings on Copper Pipe

Installing compression fittings on copper pipe is a relatively simple process. Here are the steps:

1. Cut the copper pipe to the desired length.
2. Deburr the ends of the pipe.
3. Slide the ferrule onto the pipe.
4. Insert the pipe into the body of the fitting.
5. Tighten the nut onto the body.

Troubleshooting Compression Fitting Leaks

If you are experiencing leaks from a compression fitting, there are a few things you can check:

• Is the fitting properly tightened?
• Is the ferrule damaged?
• Is the pipe properly deburred?
• Is the fitting the correct size for the pipe?

If you have checked all of these things and the leak persists, you may need to replace the fitting.

Other Uses for Compression Fittings

In addition to connecting copper pipes, compression fittings can also be used to connect other types of pipes, such as:

• PEX pipe
• CPVC pipe
• ABS pipe
• PVC pipe

Wrapping Up

Compression fittings are a versatile and easy-to-use option for connecting copper pipes. They are a cost-effective and leak-proof solution that can be installed quickly and easily. By following the steps outlined in this guide, you can ensure that your compression fittings are installed correctly and will provide years of trouble-free service.

Frequently Asked Questions

• Q: Can compression fittings be used on copper pipes that are already soldered?
• A: No, compression fittings cannot be used on copper pipes that have already been soldered. Soldering creates a permanent bond between the pipe and the fitting, and compression fittings cannot create a seal on a soldered surface.
• Q: Can compression fittings be used to connect copper pipes of different sizes?
• A: Yes, there are compression fittings available that can connect copper pipes of different sizes. These fittings are called “reducers” and they are available in a variety of sizes.
• Q: How long do compression fittings last?
• A: Compression fittings can last for many years if they are properly installed and maintained. However, the lifespan of a compression fitting can be affected by factors such as the quality of the fitting, the type of pipe it is used on, and the environment in which it is installed.
