Опорное кольцо, наружный диаметр 66,03 мм Caterpillar 5034815

A Back-Up Ring inside the hydraulic cylinder of the valve manifold is positioned at the plug above the O-ring seal. Its primary purpose is to safeguard the O-Ring seal from extrusion during high-pressure operations and to give resistance support. By reducing the extrusion gap, the Back-Up Ring effectively shields the O-ring, preventing it from being forced into areas where it could be damaged or compromised under intense pressure. This protective mechanism ensures the longevity and reliability of the O-Ring seal, even in demanding hydraulic applications. The design of the Back-Up Ring takes into account the specific hydraulic system's requirements, including the type of fluid, pressure levels, and operating temperatures. Properly implemented, the Back-Up Ring can extend the service life of the O-Ring seal and contribute to the overall efficiency and reliability of the hydraulic system.Attributes: • Reduces extrusion gap to safeguard the O-Ring from damage or compromise• Resilient and durable materials to withstand hydraulic forces• Ensures a proper fit and optimal sealing performance• Easy installation and quick maintenanceApplication:This Back-Up Ring used in the hydraulic cylinder inside the valve manifold positioned in the plug protects the O-Ring seal from extrusion at high-pressure operations. It is done by reducing the extrusion gap by the Back Up Ring.
