Hydraulic ferrules are small metal sleeves that are used in hydraulic systems to connect two pieces of hydraulic tubing or hose together. They work by creating a tight seal between the two pieces of tubing or hose, which prevents hydraulic fluid from leaking out.
To create a seal, the hydraulic ferrule is placed over the end of the tubing or hose and then crimped tightly using a specialized tool. The crimping process compresses the ferrule around the tubing or hose, which deforms it and creates a tight seal.
The hydraulic ferrule is typically made of a durable metal, such as steel or brass, that can withstand the high pressures and temperatures that are common in hydraulic systems. The ferrule is also designed with a specific shape and size that is compatible with the tubing or hose being used.
