A ferrule is a small, typically cylindrical component that is used to reinforce, protect, or cap the end of a cable, wire, tube, or pipe. Ferrules are essential in providing mechanical strength, electrical insulation, and protection against environmental elements, ensuring a secure and reliable connection. They are widely used across multiple industries, including electrical, mechanical, and plumbing systems.

Key Features

• Material: Ferrules are typically made from metals like brass, copper, aluminum, or stainless steel for their excellent strength, corrosion resistance, and conductivity. Some ferrules, especially for electrical applications, may have a coating of tin or nickel to further enhance conductivity and corrosion resistance.
• Shape: Ferrules are typically cylindrical, with one end being crimped or compressed to fit the wire or cable snugly, and the other end serving as a protective cap or connection point.
• Size: Ferrules come in various sizes, depending on the type of cable or wire they are designed to fit. The internal diameter of the ferrule corresponds to the diameter of the wire, while the external diameter is designed for the connector or terminal it will fit into.
• Design: Some ferrules are designed with a small flange or lip to prevent the ferrule from sliding off when crimped, providing added stability and security in the connection.
