Introduction
When it comes to high-performance aircraft and aerospace systems, reliability is non-negotiable—especially when dealing with hydraulic and fuel lines. That’s where Permaswage comes in. This advanced tube fitting technology is trusted across the aerospace industry for its ability to create permanent, leak-proof connections in high-pressure systems.
What Is Permaswage?
Permaswwage is a mechanical tube joining system that creates a permanent metal-to-metal seal by cold-working the fitting material around the tubing. This process eliminates the need for welding, flaring, or threaded connections, which can weaken over time.
Originally developed for aerospace applications, the system is widely used by OEMs, MRO facilities, and military operations due to its superior strength, reliability, and resistance to vibration and pressure.
How Does It Work?
The Permaswage system uses specially designed tools and fittings to swage (or compress) a collar or sleeve around a tube and insert. The result is a robust, tamper-proof joint that maintains integrity even under extreme conditions.
The basic process involves:
Inserting the tube into the fitting or ferrule
Using a hydraulic swaging tool to apply radial force
Cold-forming the fitting around the tube to create a tight seal
There are rigid (straight) and flexible (soft) Permaswage options depending on system requirements.
Why Is Permaswage Used?
- Permanent, reliable joints
- Faster installation than welding or brazing
- High-pressure capabilities
- Vibration resistance
- Weight savings, which is crucial in aerospace
Where Is Permaswage Used?
- Aircraft hydraulic and fuel systems
- Military and commercial aviation
- Spacecraft and defense systems
- Submarine and marine applications
