When it comes to working with cross-linked polyethylene, or PEX pipes, a crucial part that you can’t ignore is the PEX clamp. In this article, we’ll take a closer look at what PEX clamps are, why they’re so important, and share some tips on how to take them off effectively.
PEX clamps, also known as PEX cinch clamps, are small, strong rings made from stainless steel. Normally, they are used to attach PEX pipes to different parts like faucets or valves in your house.
Moreover, they play an important role in a PEX pipe system. Without them, the system would not be able to keep water from leaking, and this could cause serious water damage and possible health risks. When you use these clamps, the pipe system stays strong and lasts longer.
Indeed, removing these clamps can be quite simple once you get the hang of it. Here are 2 methods to help you navigate the process with ease:
Here, we will provide you with a step-by-step guide to removing these clamps:
Step 1: Preparing the pipe
First, identify the PEX clamp you wish to remove. Now, to begin, you need to cut the PEX pipe where the fitting assembly meets the pipe. In the process, use a pipe cutter for this task. Aim to cut close to the fitting. However, leave about 1/2” – 3/4“ of pipe. This leftover piece of pipe will make it easier to get a hold of the pipe with a plier for removal in the next step.
Step 2: Cut and remove the clamp
Now that the pipe is prepared, it’s time to deal with the clamp. To do this, position the cutting jaw of your end-cutter on each side of the clamp ear. Next, squeeze the handles of the cutter until the jaws successfully cut entirely.
Following this, use the jaws to grip one of the cut ends. By applying a little force, you can open and then remove the clamp from the pipe.
Step 3: Detaching the PEX pipe
The last step is to remove this pipe from the fitting. This might be a bit difficult. To overcome this, get a strong grip on the PEX pipe with a pair of pliers. With a firm grip, start twisting the pipe to remove it from the fitting.
If the pipe proves too stubborn, you may need to cut part way through the pipe to loosen it. However, ensure that you exercise great caution during this process.
Additionally, if this is your first time doing this, it might take a few tries before you get the hang of it. But don’t worry, with practice, you will become proficient at removing PEX clamps with tools, ensuring that your home’s plumbing system remains in good shape.
Now, we give you a step-by-step guide to removing PEX clamps with common tools:
Step 1: Preparing the pipe
First, you should locate the PEX clamp you want to take off. Now, take a pipe cutter and slice the PEX pipe near where it’s connected to the fitting. Aim to cut so that you leave a little bit of pipe, about 1/2” – 3/4“, still attached to the fitting. This extra bit of pipe will make it simpler to grip with pliers when we reach the final step.
Step 2: Loosening the clamp band
Once you’ve prepared the pipe, take a flat-headed screwdriver or the jaws of side cutters, and slide them under the clamp band’s tab. Then, gently lever up the end to disengage the interlocking tab mechanism. This movement will help loosen the clamp’s hold on the pipe.
Step 3: Take off the clamp
When the clamp band is loose, take side cutters or pliers to hold onto the loosened tab. With a firm pull, you can fully open the clamp band and slide the clamp off the pipe. This step may require a bit of strength, but it shouldn’t be too difficult with the right tools.
Step 4: Pulling out the PEX pipe
At last, it’s time to remove this pipe. The tiny barbs on the PEX fittings can make this step a bit tough, as they hold tightly to the pipe. To overcome this, get a strong hold on the PEX pipe with pliers and twist to take the pipe off the fitting.
Additionally, if the pipe is stubborn, you can cut it slightly into the pipe to help ease it off. But be careful! Make sure not to cut all the way through and damage the fitting.

Here’s a simple, step-by-step process to help you achieve this task:
Step 1: Loosen the fittings or remove adhesives
Begin this process by loosening the fittings or removing any adhesives that may be present. This can be done manually, without the need for tools. If it’s a threaded joint, turn it counterclockwise to loosen the connection. In case adhesives have been used to secure the fitting, try to gently peel it off using your fingers. Remember, take your time and be patient to prevent any damage.
Step 2: Remove the components
After loosening the fittings or peeling off the adhesive, it’s time to take the PEX materials out. Firmly, yet gently, grasp the PEX pipe and pull it away from the fitting. In the process, make sure to apply consistent force and avoid dragging it suddenly to prevent any potential damage or injury.
Step 3: Disassemble the parts
Lastly, be careful in this stage to prevent causing any permanent damage to the materials. Make sure you keep all the disassembled parts in one place once they’re separated. This avoids misplacing them and makes it easier when you want to put them back together or substitute them.
Maintaining your PEX clamps regularly plays a pivotal role in enhancing the lifespan and performance of this piping system. Below are a few steps you can take to ensure regular maintenance:
- Routine inspection: Always keep an eye on your PEX clamps. Regularly check for any visible signs of damage, such as rust, corrosion, or noticeable cracks in the clamps.
- Clamp tightness: Periodically test the tightness of these clamps. Over time, clamps can become loose due to temperature changes or normal wear and tear. If you find any loose clamps, they should be tightened or replaced to prevent any possible leaks.
- Check for leaks: Be careful with any water leakage around the PEX clamps. Even the smallest leak can turn into a major issue.
- Professional inspection: Consider scheduling a professional inspection of your plumbing system annually.
- Replacement of damaged clamps: If during your checking, you find any clamp that is severely damaged, consider replacing it immediately.
- Cleaning: Clean these clamps regularly. This helps prevent the build-up of grime and corrosion, thus enhancing their lifespan.
PEX clamps play a vital role in maintaining a robust and reliable plumbing system. By understanding their function and learning to install and remove them effectively, you’ll be well on your way to mastering your home plumbing tasks.
Yes, of course, the installation of PEX pipes requires not only a certain level of skill but also a specific tool. The unique clamps used with PEX piping are engineered to create a tight and secure seal, but to ensure this, you must use the appropriate pinch clamp tool.
Absolutely, stainless steel pinch clamps, sometimes known as ear clamps, are an effective method for joining PEX pipe to PEX fittings. The use of SS pinch clamps with an interlocking design can result in a connection just as robust and reliable as one made with a copper crimp ring.
Yes, if you lack an end cutter, you can still remove a PEX clamp using side-cut pliers and a flat screwdriver. Furthermore, in challenging situations where the clamp needs to be removed while the fitting is still in the system, a heavy-duty end cutter might make the task simpler.
