УПЛОТНЕНИЕ Caterpillar 1989428

The Stick Cylinder Plug Seal secures the hydraulic seal around the plug in the stick cylinder assembly. Prevent hydraulic fluid from escaping and maintain internal system pressure during cylinder operation. The seal ensures the plug remains leak-free, protecting the system from pressure loss that impairs movement. Keeping the hydraulic path fully contained reduces the risk of component wear caused by fluid contamination or pressure imbalance. Attributes:• Ensures the plug remains securely seated in its position.• Minimizes energy loss due to pressure drops in the system.• Prevents hydraulic fluid leakage from the plug interface.Applications: The Stick Cylinder Plug Seal is located at the plug interface of the stick cylinder in hydraulic systems, sealing hydraulic fluid within the chamber to maintain pressure and ensure smooth movement during digging, lifting, and holding operations.
