The Differences

Although crimping and cinching aim towards achieving a perfect connection, they differ in varying aspects.


Cinch tools are advantageous due to their versatile nature. You only require one device for multiple projects. This saves you money because you won’t need to buy other tool sizes. Furthermore, the cinching tools are more flexible for both tiny spaces since they require little effort. You can also use them with both copper and stainless steel rings.

When it comes to the crimping method, usually, crimp tools make connections for only a single size of PEX fittings. They are designed in angle or straight models with the former featuring shorter handles. Also, they are flexible enough to be used in hard to reach area.

Some versions of crimp tools work with two PEX sizes like ½ inch and ¾ inch.  Although you won’t need to purchase another tool of different size, the dual-size tools are much complicated to use than the single-sized tools. As an alternative, PEX crimp devices come with interchangeable jaws to fit various sizes of pipes.

As a professional plumber, you want your work to be fast, easy, and perfect with the first attempt. The crimping method is very popular with its ease of use. You don’t require any special skills to use crimping tools. This makes them suitable for both beginners and experts. On the other hand, cinching is relatively technical and requires expertise. However, it is easy to remove the clamps if you make a mistake.


Crimping involves copper rings while cinching woks with stainless steel rings. Because copper is more prone to corrosion than the latter, it is less durable. The copper material can also cause damage to the pipe system due to freezing water.

When sealing pex pipes, you can use either a pex clamp tool or a pex crimp tool as they serve the same purpose. However, there are unique differences between these two. The pex crimp tool is limited to using copper and it crimps the whole crimp ring. With the clamp tool, you get to use different materials ranging from copper to stainless steel, it however  cinches just one section of the whole fitting.

When it comes to which method is better between crimping and cinching, it all comes down to personal preference and workload. If you are looking for a fast and more secure connection that will stand the test of time, crimp tools are your better option. But if you want more flexibility without working more, go for PEX clamps.
