Threaded Cross

Threaded Cross is a type of pipe fitting used in plumbing and industrial piping systems. It is designed to connect four pipes at 90-degree angles, forming a cross shape. Unlike butt weld or socket weld fittings, threaded crosses use threaded connections, which means the pipes are screwed into the fitting rather than welded.

What is Threaded Cross

Threaded Cross is a pipe fitting with four threaded openings arranged at 90-degree angles, used to connect four pipes in a piping system. It allows fluid or gas to flow in four directions and is installed by screwing threaded pipes into its ends.


Made from materials like stainless steel, carbon steel, or brass, it is commonly used in low to medium-pressure systems such as plumbing, gas distribution, and irrigation.


Its key advantages include easy installation, reusability, and versatility. However, it is not suitable for high-pressure or high-temperature applications due to potential leak risks at threaded joints.

Advantages of Socket Weld Cross

Ease of Installation: Pipes can be easily screwed into the fitting without welding.


Reusability: Can be disassembled and reused, making it ideal for temporary or modular systems.


Versatility: Suitable for a wide range of applications, including plumbing, gas, and low-pressure industrial systems.


Applications of Threaded Cross

Plumbing Systems: Connects water supply lines in residential or commercial buildings.


Gas Distribution: Used in low-pressure gas lines for distribution.


Industrial Systems: Suitable for low-pressure fluid transport in machinery or equipment.


Fire Protection Systems: Distributes water in fire sprinkler systems.


Irrigation Systems: Connects pipes in agricultural or landscape irrigation.
