In the world of plumbing, there are various methods and techniques used to ensure leak-free connections. Two popular methods that have gained significant attention in recent years are pex crimping and pex clamping. Both methods provide secure connections, but each has its own advantages and disadvantages. In this article, we will explore the differences between pex crimping and pex clamping and determine which method is the best choice for your plumbing needs in 2023.

What is Pex Crimping?

Pex crimping is a method of joining pex pipes using copper crimp rings. This method involves using a crimping tool to compress the copper ring onto the pipe and fitting, creating a tight and secure connection. The crimping process requires skill and precision to ensure proper compression of the ring without damaging the pipe.

What is Pex Clamping?

Pex clamping, also known as cinch or clamp method, is an alternative to crimping. This method uses stainless steel clamps instead of copper rings to secure the pipe and fitting together. The clamps are placed over the pipe and fitting and tightened using a cinch tool, providing a reliable and durable connection.

Advantages of Pex Crimping

One major advantage of pex crimping is its compatibility with a wide range of fittings and pipes. Crimp rings are available in various sizes, allowing for versatility in plumbing projects. Additionally, crimping tools are relatively affordable and easy to use, making this method accessible to both professionals and DIY enthusiasts.

Advantages of Pex Clamping

Pex clamping also offers several advantages. Stainless steel clamps are resistant to corrosion and can be reused, reducing the overall cost of plumbing projects. This method requires fewer tools compared to crimping, making it a more cost-effective option for occasional plumbing tasks. Furthermore, clamps provide a visible indication of a secure connection, giving homeowners peace of mind.

Disadvantages of Pex Crimping

While pex crimping is widely used, it has a few drawbacks. The crimping process requires a steady hand and practice to achieve consistent and secure connections. Inexperienced individuals may struggle to properly compress the copper ring, leading to leaks or weak connections. Additionally, crimp rings are not reusable and must be cut off if repairs or modifications are needed.

Disadvantages of Pex Clamping

Pex clamping also has its limitations. Although stainless steel clamps are durable, they can be more expensive compared to copper rings. The cinch tool used for clamping can also be more expensive than a crimping tool. Furthermore, the cinch method is not compatible with all types of pex fittings, limiting its versatility in certain plumbing projects.

Which Method is Best for You?

Choosing between pex crimping and pex clamping ultimately depends on your specific needs and preferences. If you prioritize versatility, affordability, and accessibility, pex crimping may be the ideal choice for you. On the other hand, if you value durability, reusability, and ease of installation, pex clamping might be the better option.


Both pex crimping and pex clamping offer reliable and secure connections for plumbing projects. Understanding the advantages and disadvantages of each method will help you make an informed decision based on your requirements. Whether you choose pex crimping or pex clamping in 2023, it is essential to follow manufacturer guidelines and use high-quality materials to ensure long-lasting and leak-free plumbing connections.
