Threaded Socket
What is a Threaded Socket?
A Threaded Socket, also referred to as a Threaded Coupling, is a short pipe fitting used to connect two pipes of the same or different sizes via female threads. Designed for low to medium-pressure piping systems, these fittings allow for easy and secure straight-line pipe connections without welding.
Threaded sockets are commonly used in water pipelines, oil & gas networks, fire protection systems, and compressed air lines, and are available in full, half, and reducing types to suit various piping layouts.
Key Features
- Inline Connectivity – Designed for joining two pipe sections in a straight line.
- Quick Installation – No welding required; easy to assemble and replace.
- Multiple Variants – Available in full, half, and reducing configurations.
- Thread Versatility – Supports NPT, BSP, and BSPT thread standards.
- Robust & Corrosion-Resistant – Reliable under pressure and harsh conditions.
Types of Threaded Sockets
- Full Coupling
- Half Coupling

Do you have questions?
What is the difference between a full and half coupling?
A full coupling has threads on both ends, while a half coupling has threads on one side and a plain end for welding or socketing.
Are reducing couplings available?
Yes, we offer reducing couplings to connect pipes of differing diameters.
What thread types do you support?
We provide NPT, BSP, BSPT, and custom threads as per client needs.
Are threaded couplings reusable?
Yes, provided the threads are undamaged and properly sealed during reassembly.
