The Screw Plug is a threaded closure component used to seal off fluid ports and passageways in hydraulic, lubrication, or cooling systems. The plug ensures that the internal fluid containment is maintained and that contaminants do not enter the closed system. With standardized thread patterns and durable sealing surfaces, the Screw Plug is a compact element in maintaining system integrity and service accessibility.Attributes:• Threaded design ensures tight sealing under fluid pressure.• Prevents leakage in closed hydraulic lubrication circuits.• Facilitates controlled adjustment of seal integrity under temperature cycles.Applications: The Screw Plug is used to block off inspection ports, test points, or unused threaded connections in hydraulic and lubrication systems during operation and maintenance.
