Ferrules are used to make secure connections and seals, preventing leaks or fraying.
Components:
A ferrule fitting is made up of a nut, one or two ferrules (or compression rings), and a body. The ferrule is compressed against the tubing as the nut is tightened.
Types:
Single ferrule fittings: Simpler and often used for lower-pressure applications.
Double ferrule fittings: Use two ferrules for a more secure seal, often in high-pressure, high-vibration, and high-temperature applications.
Applications:
Fluid systems: Connecting and sealing tubes in hydraulic and pneumatic systems, from low-pressure plumbing to high-pressure industrial lines.
Electrical systems: Crimp onto the ends of wires to keep strands together, prevent fraying, and ensure a solid electrical connection.
Other uses: As protective sleeves, or as caps on furniture legs and walking sticks.
