Description
Steel Coupling 1/4" BSP Weldable
- Size: 1/4"
- Material: Carbon steel
- Thread type: BSP (also known as G, Rp, parallel pipe thread)
- Dimension B: 18 mm
- Dimension L: 25 mm
- Suitable for welding
- Applications: Industrial installations, agricultural machinery, central heating systems
Alternative Name
Steel Coupling 1/4" BSP Weldable, Carbon Steel Threaded Coupling, BSP Pipe Coupling, Female Thread Coupling, Steel Socket, Threaded Pipe Coupling
Information
The 1/4" BSP Steel Coupling is manufactured from carbon steel and is designed for joining threaded pipes and fittings in industrial and heating systems. The fitting features female BSP threads on both ends, ensuring compatibility with standard BSP (G/Rp) threaded piping systems.
Its robust construction and excellent weldability make it a reliable solution for industrial installations, central heating systems, agricultural machinery, and general engineering applications.
Material
Carbon steel provides high mechanical strength, good machinability, and excellent weldability. It is widely used in industrial piping, heating systems, machinery, and general-purpose engineering applications.
Advantages
- Carbon steel construction
- BSP female threads
- Excellent weldability
- High mechanical strength
- Reliable threaded connection
- Suitable for industrial applications
Applications
Industrial installations, agricultural machinery, central heating systems, water installations, compressed air systems, and general-purpose piping.
We also offer steel couplings in many other sizes. If you have any questions, please contact us. Call +48 63 261 42 02 or email biuro@polberis.pl.
