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. The assembly includes an O Ring Face Seal Sleeve, and Nut to ensure a secure and leak-free connection.Attributes:• Withstands 28000 kPa relief valve pressure• Provides precise control over attachment engagement and disengagementApplications: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.
