304 Stainless Steel BSP Male Hex Plug — End Blanking Stop Fitting

Match the plug size to your pipe's nominal bore (DN) rating. DN8 fits 1/4" BSP ports, DN15 fits 1/2" BSP, DN25 fits 1" BSP, and DN50 fits 2" BSP. Always verify the thread size stamped on your fitting or valve body before ordering. If you are between sizes, the thread pitch on a BSP port will confirm the correct nominal size.

304 stainless steel BSP male plugs generally handle working pressures up to 150 PSI (approximately 10 bar) in standard plumbing and hydraulic applications. Actual ratings depend on pipe wall thickness, temperature, and installation quality. Contact us to confirm for your specific application.

Yes. 304 stainless steel offers good corrosion resistance for most outdoor, marine-adjacent, and mildly corrosive environments. For highly chlorinated or saltwater-immersion applications, 316 stainless steel is typically recommended instead. If your environment involves strong acids, chlorides, or aggressive chemicals, please contact us before ordering.

These plugs use BSP (British Standard Pipe) threads, also known as G-thread or Whitworth pipe thread. BSP is widely used in plumbing, pneumatics, and hydraulics across the US, UK, Europe, and Asia. They are not compatible with NPT (National Pipe Taper) threads without an adapter. Check your port markings — BSP ports are typically labeled "G" or "BSP", while NPT ports are labeled "NPT" or "NPS".

These plugs feature a hex socket (Allen key) drive on the end face. You will need a hex key (Allen wrench) or hex bit socket of the appropriate size for the plug diameter you ordered. The hex drive allows installation in recessed or tight-clearance ports where a standard wrench cannot reach — a common requirement in hydraulic manifolds and compact valve assemblies.

For liquid or gas applications, applying PTFE thread tape or a compatible thread sealant compound is generally recommended to ensure a leak-free seal. BSP parallel (BSPP/G) threads in particular rely on a face seal or sealant rather than thread taper alone — unlike tapered NPT threads which can self-seal under torque. Always follow the sealant manufacturer's compatibility guidelines for your media.

In most cases, yes — 304 stainless steel BSP hex plugs are commonly used to blank off unused ports in hydraulic manifolds, pneumatic cylinders, and compressed air systems. Always verify the pressure and temperature ratings match your system requirements before installation. For high-pressure hydraulic circuits (above 150 PSI), contact us to confirm suitability.

Generally, yes. Stainless steel BSP hex plugs can typically be removed and reinstalled multiple times without significant thread wear, provided they are not overtightened and the threads are kept clean. Inspect the threads and apply fresh sealant tape each time you reinstall for a reliable seal.
