Threaded Cross
What is a Threaded Cross?
A Threaded Cross is a four-way pipe fitting with one inlet and three outlets (or vice versa), each with female threads. It’s used to create multi-directional branches in a piping network. These fittings are ideal for complex layouts in chemical plants, process skids, compressed air systems, and fluid control panels.
Threaded crosses simplify the design of compact piping arrangements where multiple lines intersect.
Key Features
- Four-Way Flow – Ideal for branching or collecting fluid in pipelines.
- Efficient Distribution – Enables organized multi-directional flow.
- Weld-Free Assembly – Easy to install, adjust, or replace.
- Industrial Strength – Built for high-pressure applications.
- Thread Versatility – Supports NPT, BSP, BSPT, and more.
Types of Threaded Cross
- Equal Threaded Cross
- Reducing Threaded Cross
- 4-Way Female Threaded Cross

Do you have questions?
When should a threaded cross be used?
Use a threaded cross when multiple branches need to diverge from one central line, especially in compact piping grids.
Are reducing crosses available?
Yes, we offer reducing crosses with customized branch sizes for specific layouts.
Can these be used in high-temperature applications?
Yes. When made from the right alloy (like SS 316 or Alloy Steel), they perform well under high temperatures.
Are threaded crosses tested for leakage and pressure?
All fittings undergo dimensional and pressure testing. Certifications like MTC, TPI, and hydro test reports are provided as required.
