Alternative Name

3/4" BSPT Coupling Class 3000 Stainless Steel 304L (1.4307), Stainless Steel Threaded Coupling, Female BSPT Coupling, High-Pressure Coupling, Straight Coupling, SS304L Coupling, BSPT Female Adapter

Information

The 3/4" BSPT 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 BSPT tapered threads on both ends, ensuring secure and leak-tight 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)
BSPT tapered 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.
