ASTM A105N Threaded Coupling Specification
ASTM A105N threaded couplings are used in piping systems to connect two pipes with threaded ends. They are made from carbon steel conforming to ASTM A105N, a normalized grade of ASTM A105, which enhances its mechanical properties and improves toughness.
| Types | Full Coupling , Half Coupling |
| Shapes | Con-coupling , Red-coupling |
| Normal Size | 1/8”– 4” / DN6 – DN100 |
| Class | Class 3000lbs , 6000lbs |
| Production Standard | ASME B16.11, BS3799, GB/T 14383 |
| Thread mode | NPT, PT, BSPP, BSPT, PF |
Types of Threaded Couplings
Full Coupling
– Connects two pipes of the same diameter.
– Fully threaded inside.
Half Coupling
– Has internal threads on one end and a plain end on the other.
– Used for branching off a pipe or welding one end to a larger structure.

Threaded Couplings Key Features
Connecting Pipes:
The primary function is to extend pipe runs or connect sections of piping.
Connecting Fittings:
They can also be used to join other threaded fittings, such as valves or other components.
Ease of Installation:
Threaded connections are relatively easy to install and disassemble, making them useful for applications where maintenance or modifications may be required.
Applications:
– Threaded couplings are found in a wide range of applications, including:
– Plumbing systems
– Industrial piping
– Pneumatic and hydraulic systems
– Irrigation systems
