The Protection Plug prevents external contaminants from entering internal cavities where controlled movement and lubrication are required. Sealing these openings helps maintain stable internal conditions that support consistent performance. It restricts unintended fluid escape from access points, reducing the risk of leakage during operation.Attributes:• Maintains enclosed operating conditions within assemblies.• Supports clean internal movement of connected components.• Minimizes exposure of internal passages to external elements.Applications: The Protection Plug is inserted into open ports on hydraulic pumps, valves, and cylinders. It seals these openings during transit and repair to maintain system purity and prevent fluid loss.
