A Coupler Lines Tube Assembly is responsible for channeling the hydraulic fluid to and from hydraulic cylinders. The tube is carefully routed and secured to prevent damage from vibration, and impact. The inner surface of the tube is made smooth to minimize back pressure and reduce turbulence.Attributes:• Ensures efficient flow of hydraulic fluid• Provides controlled extension and retraction of coupler cylinder piston rodApplications:A Coupler Lines Tube Assembly is used to facilitate the flow of hydraulic fluid to and from the reservoir to actuate the coupler cylinder attached with the stick arm of the machine.
