Alternative Name
Coupling 1/4" BSP Class 3000 Stainless Steel 316L (1.4404), Heavy-Wall High-Pressure Coupling, Stainless Steel Threaded Coupling, BSP Female Coupling, SS316L Coupling, Straight Coupling
Information
The 1/4" BSP Class 3000 Coupling is manufactured from 316L stainless steel (1.4404) and is designed for high-pressure threaded piping systems. Its heavy-wall construction provides excellent mechanical strength and allows 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
316 / 316L stainless steel is one of the most widely used austenitic stainless steels. It offers excellent corrosion resistance, outstanding weldability, and excellent forming properties, making it suitable for demanding industrial environments.
Equivalent material designations include:
- DIN 1.4401
- DIN 1.4404
- SS316
- SS316L
- AISI 316
- AISI 316L
Advantages
- Stainless steel (inox)
- Heavy-wall construction
- Female BSP parallel 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, high-pressure piping systems, and industrial process installations.
