Threaded Tee
What is a Threaded Tee?
A Threaded Tee is a three-way pipe fitting used to combine or split the flow of fluids in a pipeline. Each port of the tee features a female threaded end that allows easy and leak-proof connection of pipes, especially in maintenance-heavy or retrofit systems. Threaded tees are widely used in plumbing, oil & gas, water treatment, chemical processing, and HVAC.
Available in both equal and reducing variants, these tees allow either uniform or variable size branching of pipelines.
Key Features
- 90° Branch Connections – Ideal for creating perpendicular flow lines.
- Flexible Design Options – Available in both equal and reducing configurations.
- Hassle-Free Installation – Threaded ends eliminate the need for welding.
- Thread Compatibility – Offered in NPT, BSP, and BSPT thread types.
- High-Pressure Durability – Built to withstand demanding operating conditions.
Types of Threaded Tees
- Equal Threaded Tee
- Reducing Threaded Tee
- Female Threaded Tee
- Male-Female Thread Tee (custom)

Do you have questions?
What is a threaded tee used for?
It connects three pipe sections and allows fluid to branch or merge, often at 90° angles.
Do you offer custom size combinations for reducing tees?
Yes. We manufacture custom-reducing tees as per client drawings or specifications.
Are threaded tees suitable for drinking water applications?
Yes, when made from SS 304 or SS 316, they are safe for potable water systems.
Can I get tees with BSPT threads?
Absolutely. We offer BSP, BSPT, NPT, and metric threads based on customer requirements.
