Structure: One end is a connection end with a ring-shaped hole (through which bolts can be passed to achieve articulated connection with equipment or other components), and the other end is a core tube with a toothed pattern (used for crimping connection with hydraulic rubber hoses).

Function: In hydraulic pipelines, it enables the pipelines to move within a certain Angle range, adapting to equipment vibration, displacement and other conditions, ensuring the stability of oil circuit connections. It is often used in hydraulic systems of construction machinery, mining machinery and other equipment with relatively moving parts, such as the connection between cylinders, swing motors and pipelines.

Advantages: Compared with ordinary straight cylinder joints, the hinged design can reduce the stress caused by hard connections in the pipeline, extend the service life of the rubber hose and joint, and enhance the reliability of the hydraulic system.
