Threaded Socket
What is a Socket (Threaded Coupling)?
A Threaded Socket, also known as a Threaded Coupling, is a bar stock fitting designed to connect two male-threaded pipes in a straight-line configuration. It features female threads on both ends and is widely used in low- to high-pressure piping systems where welding is not feasible or desired.
Threaded sockets are available in full, half, and reducing types and are commonly used in plumbing, hydraulic circuits, compressed air systems, and oil & gas installations.
Key Features
- Inline Female Threaded Connection – Joins two threaded male pipes.
- Multiple Configurations – Available as full, half, and reducing sockets.
- Leak-Resistant Performance – Machined to precise tolerances for secure fit.
- Non-Welded Installation – Ideal for removable and modular piping systems.
- Standard Compliant Build – Meets ASME, DIN, MSS-SP, and BS specs.

Do you have questions?
What’s the difference between a full and half socket?
A full socket has threading on both ends, while a half socket connects a male-threaded pipe to a butt-weld or socket weld end.
Can you supply reducing sockets?
Yes, we offer reducing couplings/sockets to connect pipes of different diameters.
Are threaded sockets reusable?
Yes, as long as the threads remain intact and sealing material is replaced.
Do you provide test certificates?
Absolutely. MTCs and third-party inspection certificates are available on request.
