Alternative Name
Coupling 3/4" BSP Class 3000 Stainless Steel 304L (1.4307), Stainless Steel Threaded Coupling, Female BSP Coupling, High-Pressure Coupling, Straight Coupling, SS304L Coupling, BSP Female Adapter
Information
The 3/4" BSP Class 3000 (206 bar) Coupling is manufactured from 304L stainless steel (1.4307) and is designed for high-pressure threaded piping systems. Its thick walls provide excellent mechanical strength and allow safe operation at pressures up to 206 bar.
The fitting features female BSP parallel threads on both ends, ensuring secure and reliable threaded connections in demanding industrial applications.
Material
304/304L stainless steel (1.4307) is one of the most widely used austenitic stainless steels. It offers excellent corrosion resistance, outstanding weldability, and high mechanical strength. It is commonly used in the food processing, pharmaceutical, brewing, marine, and general industrial sectors.
Advantages
- Stainless steel (inox)
- BSP parallel female threads
- Pressure class: Class 3000 (206 bar)
- Excellent corrosion resistance
- Excellent weldability
- Non-magnetic material
- Excellent ductility and impact resistance
- Wide operating temperature range
- 3.1 material certificate available on request
Applications
Heat exchangers, pharmaceutical equipment, dairy installations, breweries, marine fittings, coastal structures, food processing, pressure piping systems, refineries, and industrial process installations.
Marking
Each coupling is permanently marked with:
- Size
- Material grade
- Heat number
- Pressure class
- Thread type (where applicable)
All markings comply with the applicable industry standards.
Notes
Advantages: Easy selection of thread type and material grade.
Limitations: Not available with metric threads.
