Proper tube preparation is essential to every successful Permaswage® installation. Before a fitting can be installed and swaged, the tube must be cut, deburred, cleaned, and inspected to ensure the highest quality connection.
Permaswage® Deburring Tools are specifically designed to remove internal burrs from tubing after cutting. When used with the correct stem assembly, these tools help create a smooth tube entrance that supports proper fitting installation and helps protect seals from damage.
In this guide, we'll explain how Permaswage® Deburring Tools work, provide a complete list of tool and stem assembly part numbers, and discuss why proper deburring is critical to the swaging process.
What Is a Permaswage® Deburring Tool?
A Permaswage® Deburring Tool is a reusable hand tool designed to hold interchangeable stem assemblies for removing internal burrs from tubing.
After a tube is cut, small burrs and sharp edges are often left inside the tube. These burrs can interfere with fitting installation, damage seals, and introduce contamination into hydraulic, fuel, or pneumatic systems.
Using the proper deburring tool helps ensure the tube is ready for the next steps in the installation process.
Why Is Deburring Important?
Deburring is one of the most important tube preparation steps because it helps eliminate sharp edges that could negatively affect the installation.
Proper deburring helps:
- Protect fitting seals
- Reduce contamination
- Improve fitting insertion
- Support proper swage quality
- Reduce installation damage
- Improve long-term reliability
Skipping the deburring process can result in damaged fittings, seal failures, and installation issues.
How Permaswage® Deburring Tools Work
- Select the correct stem assembly for the tube size.
- Install the stem into the deburring tool handle.
- Lubricate the rubber expansion plug if required.
- Insert the stem into the tubing.
- Rotate the tool to remove internal burrs.
- Inspect the tube end.
- Clean the tool before storage.
The interchangeable stem design allows a single deburring tool handle to service multiple tubing sizes.
