The Battle of Copper Crimp Fittings and Solder

When it comes to plumbing, there are various methods and materials available to join copper pipes. Two popular options are copper crimp fittings and solder. Both these methods have their advantages and disadvantages, and choosing the right one for your plumbing needs can make a significant difference in the long run.

Understanding Copper Crimp Fittings

Copper crimp fittings, also known as press fittings, are a relatively newer method of joining copper pipes. These fittings are made of brass or copper and feature an O-ring or rubber gasket inside. The pipes are inserted into the fitting, and a crimping tool is used to compress the fitting onto the pipe, creating a secure connection.

The main advantage of copper crimp fittings is their ease of installation. They require no flame or soldering, making them a safer option for DIY enthusiasts and professionals alike. Additionally, they offer a reliable and leak-free connection, as the crimping process ensures a tight seal.

Exploring Soldering for Copper Pipes

Soldering has been a traditional method of joining copper pipes for years. It involves heating the joint and applying solder, a metal alloy, to create a bond between the pipes. This method requires a torch or soldering iron and flux, a chemical that cleans the surfaces and helps the solder flow smoothly.

One significant advantage of soldering is its versatility. It can be used for various pipe sizes and shapes, making it suitable for complex plumbing systems. Soldered connections are also known for their durability and longevity when done correctly.

Comparing the Pros and Cons

Now that we understand the basics of copper crimp fittings and soldering, let’s compare their pros and cons to help you make an informed decision:

Copper Crimp Fittings:


  • Easy and safe installation, no need for a torch or soldering iron
  • Reliable and leak-free connections
  • Can be easily disassembled and reassembled if needed


  • Requires a crimping tool, which can be an additional expense
  • May not be suitable for tight spaces or areas with limited access



  • Versatile, can be used for various pipe sizes and shapes
  • Durable and long-lasting connections when done correctly
  • Less expensive than crimping tools in the long run


  • Requires a torch or soldering iron, posing potential safety risks
  • More skill and practice needed for a proper soldered connection
  • Not easily disassembled, may require heating and re-soldering for repairs

Which One Should You Choose?

The choice between copper crimp fittings and soldering ultimately depends on your specific plumbing needs and preferences. If you’re a DIY enthusiast or prefer a safer and easier installation process, copper crimp fittings may be the right choice for you. On the other hand, if you have experience with soldering or need to work with complex plumbing systems, soldering can offer durability and versatility.

It is essential to consider factors such as budget, available tools, and the overall complexity of the plumbing project before making a decision. Additionally, consulting with a professional plumber can provide valuable insights and ensure you make the best choice for your specific situation.


Copper crimp fittings and soldering are two popular methods of joining copper pipes in plumbing systems. While both have their advantages and disadvantages, it’s crucial to assess your needs and priorities before making a decision. Whether you opt for the ease of installation with copper crimp fittings or the durability of soldering, ensuring a secure and leak-free connection is vital for the longevity of your plumbing system.
