Manufactured from straight stainless steel, the 02 NPTF Hollow Hex Pipe Plug Stnls is designed to seal 1/8-27 male NPTF threaded ports in hydraulic and industrial fluid systems. The hollow hex drive allows for installation using a hex key, making it well suited for confined or tight-clearance applications where a standard external hex tool cannot be used.
Built to SAE J476 thread specifications, the NPTF thread form provides a dry-seal connection that resists leakage without relying solely on sealant. Stainless steel construction offers corrosion resistance in demanding service environments. With an overall length of 0.300 inches and a drill size of 0.220 inches, this is a compact plug appropriate for port-sealing in manifolds, valves, and other threaded assemblies. Brennan Industries manufactures this fitting under their 5406-HP series.
