The Stainless Steel Hex Plug 316 Class 300 Threaded NPT Casting Fitting is an essential component for sealing idle ports in various pipeline systems.
Class 300-pound threaded hexagonal pipe plugs are widely used in:
- Water treatment facilities
- Chemical auxiliary pipelines
- General industrial fluid handling
- Building water supply and drainage systems
The NPT threaded connection provides a simple, effective, and reversible sealing solution, suitable for terminal sealing of various medium and low-pressure pipelines.
Our cast pipe fittings are produced using precision casting (sol silica) technology to achieve excellent dimensional accuracy and surface finish:
- Creation of wax mold
- Coating with multiple layers of refractory material
- Heating to melt wax and form hollow shell
- Pouring molten stainless steel
- Cooling and solidification
- Machining and tapping to produce final product
- Product Name: Threaded Hex Plug
- Material: Stainless Steel 316 / Casting Grade CF8M
- Standard: ASTM A351 (Material) / ISO 4144 (Dimensions, ref.)
- Fitting Type: Hex Head Plug, Casting
- Connection: Threaded NPT
- Pressure Rating: Class 300
- Application: Sealing Threaded Ports, Low-Pressure Systems
- Size: Available in various sizes
Casting plugs are used to safely block unused internal threaded ports on pipe fittings or pipelines. The most common types include:
- Hexagonal Head Plug (Hex Plug): Most common design facilitating installation and removal using standard wrenches
- Square Head Plug: Alternative design for specific tool requirements
- Round Head Plug: For specific installation space requirements
Threaded pipe fittings primarily follow two major international thread systems:
- NPT (American Standard Pipe Taper Thread): 60° thread angle, 1:16 taper for sealing (used in this product)
- BSP (British Standard Pipe Thread): 55° thread angle, available as taper (BSPT) or parallel (BSPP)
The use of CF8M/316 stainless steel ensures excellent durability and corrosion resistance:
- Superior to 304 grade in resisting chloride and general industrial corrosion
- Contains molybdenum for enhanced corrosion resistance
- Prevents thread sticking or failure due to corrosion
- Ensures long-term sealing reliability
- Enables smooth disassembly during maintenance
