The Metric Threaded Plug Protectors are to tightly seal unused metric threaded ports, protecting the system from fluid escape and external contaminants such as dust, debris, and moisture. A properly fitted plug helps retain internal pressure stability by eliminating exposed openings that may compromise performance. By keeping foreign particles out, the plug supports cleaner internal conditions and promotes dependable equipment operation. Effective sealing of service or auxiliary ports reduces maintenance concerns and contributes to consistent hydraulic or fluid system efficiency. Reliable closure of threaded connections also enhances operational safety by controlling unintended discharge.Attributes:• Ensures tight closure of metric threaded ports to avoid unwanted fluid loss.• Shields internal passages from dirt, moisture, and airborne particles.• Maintains consistent internal pressure by eliminating open connections.• Supplied in a pack size of 50 pieces.Applications: The Metric Threaded Plug Protectors are commonly fitted into spare or temporary metric threaded ports in hydraulic assemblies, manifolds, and fluid transfer equipment, and to secure open connections and protect internal passages.
