A Boom Cylinder U Cup Seal is made of rubber material, which offers flexibility, resilience, and resistance to hydraulic fluids. It has a U-shaped cross-section, which gives it the name "U cup". The seal is installed in a groove on the cylinder head and is made to make contact with the outer surface of the piston rod. It is used to provide a reliable and leak-free seal for the boom cylinder.Attributes:• Withstands the hydraulic pressure within the boom cylinder• Manufactured to precise specifications and is built for durability and reliabilityApplications:A Boom Cylinder U Cup Seal maintains contact with the cylinder head and creates a seal that prevents hydraulic fluid from leaking past the piston rod. The U-shaped design of the seal provides an effective sealing action by sealing in both directions, ensuring a reliable and leak-free hydraulic system.
