174mm Inner Diameter Piston Pump O Ring Seal Caterpillar 6379656

The Piston Pump O Ring Seal creates a secure seal inside the piston pump, preventing hydraulic fluid from leaking during operation. It ensures that pressure is maintained within the pump for efficient fluid transfer and system performance. By forming a tight barrier, the O ring helps the pump operate smoothly without loss of fluid and pressure. Attributes:• Creates a tight seal within the piston pump.• Maintains internal pressure for efficient fluid transfer.• Protects other components by preventing leakage.Applications: The Piston Pump O Ring Seal is located inside the piston pump assembly. It forms a sealing barrier that prevents hydraulic fluid leaks and maintains system pressure during pump operation.
