The Metric Threaded Plug Protectors are to tightly secure metric threaded openings in hydraulic and fluid systems, preventing unwanted fluid escape and protecting against the entry of dust, dirt, and moisture. A proper seal ensures that internal pressure levels remain consistent, supporting reliable system performance during operation. By isolating unused or service ports, the plug helps safeguard internal components from contamination that may lead to wear or malfunction. Effective closure of exposed threaded ports contributes to improved operational efficiency and enhances overall equipment reliability in demanding environments.Attributes:• Provides a secure seal to eliminate fluid seepage from threaded openings.• Shields internal systems from debris, moisture, and airborne contaminants.• Maintains consistent internal pressure by closing inactive ports.• Available in a pack quantity of 50 pieces.Applications: The Metric Threaded Plug Protectors fit into metric threaded ports of hydraulic assemblies, pumps, valves, and manifolds, and are sealed using this plug to protect against leakage and environmental contamination.
