Description

A105 Threaded (NPT/BSPT) Coupling ASME B16.11, Carbon Steel Forged fitting for Oil & gas pipelines


What Is ASTM A105 Carbon Steel Coupling?

A105 Threaded Coupling is a forged carbon steel pipe fitting used to join two threaded pipes in a straight line. Made from ASTM A105 material, it features internal NPT threads on both ends and is rated for high-pressure service (2000#–9000# per ASME B16.11). Common in oil & gas, petrochemical, and power industries, it provides a reliable, leak-tight connection without welding.
