Hey there! I’m a supplier of shouldered copper capillary tubes, and today I’m gonna share with you how to cut these tubes. It might seem like a simple task, but there are some key things to keep in mind to get a clean and accurate cut. Shouldered Copper Capillary Tube

First off, let’s talk about why you might need to cut a shouldered copper capillary tube. These tubes are used in a bunch of different applications, like in refrigeration systems, air – conditioning units, and some medical equipment. Sometimes, you need to adjust the length of the tube to fit a specific project or repair.
Tools You’ll Need
To cut a shouldered copper capillary tube, you’re gonna need a few tools. The most important one is a tube cutter. There are different types of tube cutters out there, but for copper capillary tubes, a small, precision tube cutter is the way to go. You can find these at your local hardware store or online.
You’ll also need a deburring tool. After you cut the tube, there will be burrs on the edges, and if you don’t remove them, they can cause problems in your application. A deburring tool helps smooth out those rough edges.
Another thing that can be handy is a pair of pliers. You might need them to hold the tube steady while you’re cutting, especially if the tube is really small.
Preparing the Tube
Before you start cutting, you need to make sure the tube is clean and free of any dirt or debris. If there’s dirt on the tube, it can affect the cutting process and might even damage your tube cutter. You can use a clean cloth to wipe the tube down.
Next, measure the length you want to cut. Use a ruler or a measuring tape to get an accurate measurement. Mark the spot where you’re gonna make the cut with a marker. This will help you stay on track when you’re using the tube cutter.
Cutting the Tube
Now, it’s time to cut the tube. Take your tube cutter and place it around the tube at the marked spot. Make sure the cutter is centered and the cutting wheel is in contact with the tube.
Tighten the cutter by turning the adjustment screw. You don’t want to over – tighten it, just enough so that the cutting wheel bites into the tube.
Start rotating the tube cutter around the tube. As you rotate, keep applying a little bit of pressure to the adjustment screw to gradually deepen the cut. Keep rotating until the tube is completely cut through. This might take a few turns, depending on the thickness of the tube.
Deburring the Cut
Once you’ve cut the tube, it’s time to deburr it. Take your deburring tool and insert it into the end of the tube. Gently rotate the tool to remove the burrs from the inside and outside of the tube. Make sure to be careful not to damage the tube while you’re deburring.
Tips and Tricks
- Keep the tube straight: When you’re cutting, make sure the tube is straight. If it’s bent, it can be difficult to get a clean cut, and the tube might not fit properly in your application.
- Use lubrication: If you’re having a hard time cutting the tube, you can use a little bit of lubricant on the cutting wheel. This will make the cutting process smoother and help prevent the tube cutter from getting stuck.
- Practice on scrap tubes: If you’re new to cutting shouldered copper capillary tubes, it’s a good idea to practice on some scrap tubes first. This will help you get the hang of using the tube cutter and deburring tool.
Common Mistakes to Avoid
- Over – tightening the tube cutter: As I mentioned earlier, over – tightening the tube cutter can damage the tube. It can also make it harder to rotate the cutter around the tube.
- Not deburring the tube: If you don’t deburr the tube, the burrs can cause problems in your application. They can block the flow of fluid in a refrigeration system or cause leaks.
- Cutting at the wrong angle: Make sure you’re cutting the tube at a 90 – degree angle. If you cut at an angle, the tube might not fit properly in your application.
Quality Control
As a supplier of shouldered copper capillary tubes, I know how important it is to maintain quality. After you cut the tube, take a close look at the cut. It should be clean and smooth, with no rough edges or burrs. If the cut doesn’t look right, you might need to try cutting the tube again.
You can also check the length of the tube to make sure it’s accurate. Use a ruler or a measuring tape to double – check the measurement.
Applications of Cut Shouldered Copper Capillary Tubes
Once you’ve successfully cut and deburred your shouldered copper capillary tube, you can use it in a variety of applications.
In refrigeration systems, these tubes are used to carry refrigerant between different components. The accurate length and clean cut are crucial for the proper functioning of the system.
In air – conditioning units, the tubes help transfer heat and cool the air. A well – cut tube ensures efficient heat transfer and reliable operation.
In medical equipment, such as blood analyzers or infusion pumps, shouldered copper capillary tubes are used for fluid transfer. The precision of the cut is essential to maintain the accuracy of the equipment.
Conclusion

Cutting a shouldered copper capillary tube might seem like a small task, but it requires some skill and attention to detail. By using the right tools, following the proper steps, and avoiding common mistakes, you can get a clean and accurate cut.
