Titan 432-611 O-ring / Back-up Ring Set

O-ring / Back-up Ring Set 432-611 for Hydra Series

The 432-611 o-ring and back-up ring set is a comprehensive seal replacement kit for 0528925N_2000_4000, Hydr M nad Hydra Pro Super, and Hydra M and Hydra Pro 2000_4000 equipment. This set contains a matched combination of elastomeric o-rings and rigid back-up rings designed to work together in high-pressure fluid sealing applications. O-rings provide the primary seal by compressing between mating surfaces, while back-up rings are installed on the low-pressure side of the o-ring to prevent it from extruding into the gap under high pressure. This combination is essential for maintaining reliable sealing in hydraulic cylinders, pumps, valves, and other components operating at elevated pressures. A worn or damaged o-ring can cause fluid leaks and pressure loss, while missing or deteriorated back-up rings can allow o-ring extrusion, leading to rapid seal failure. This replacement set includes all necessary o-rings and back-up rings for a specific application, ensuring proper fit and material compatibility. Installation requires careful cleaning of the gland and proper orientation of components. Regular inspection and replacement of seal sets during maintenance helps prevent system failures.
