An Expert's Guide to Threaded Equal Tee

Plumbing or irrigation systems involve various fixtures and fittings, which are essential for the system’s proper functioning. A threaded equal tee is one such component to connect three pipes of the same diameter. It forms a T shape, with one straight pipe running perpendicular to the other two. These fittings are available in various materials like brass, stainless steel, and PVC. This blog post will guide an expert to a threaded equal tee, covering its types, advantages, and applications.

What is Threaded Equal Tee?

A threaded equal tee is a plumbing fitting typically used with pipes to connect two branches of the same diameter in a pipe system. It has three female threads of the same size, creating an “equal” junction for water, gas, or other fluids to pass through. The seal between these threads prevents leakage and ensures efficient flow within a pipe system.

Types of Threaded Equal Tees

There are several types of threaded equal tee fittings available in the market. The most common ones are:

Straight: This type of tee has an equal diameter of the straight and lateral branches.

Reduced: It has a smaller diameter of the lateral outlet branch than the straight and opposite outlet branches.

Flanged: It has a flange on one of its ends, which allows it to join with pipes or fittings that have flanges.

Advantages of Threaded Equal Tees

Threaded equal tee fittings have several benefits over other types of fittings. Some of these are:

Easy to install

Threaded fittings do not require any special equipment or skill for installation. They can be easily installed by hand or with the help of a wrench.


Threaded fittings are made of high-quality materials, making them durable and resistant to corrosion and rust.


You can use threaded fittings in various plumbing and irrigation applications, such as water supply, wastewater management, and fire protection systems.

Applications of Threaded Equal Tees

Threaded equal tee fittings find their usage in multiple applications, as stated below:

Water Supply

Residential, commercial, and industrial water supply systems use threaded equal tees. They ensure proper water flow and water pressure throughout the system.

Wastewater Management

Threaded equal tees find their usage in wastewater management systems, ensuring proper distribution and wastewater flow without any leakage.

Fire Protection Systems

Threaded equal tees are crucial for fire protection systems. They help in the proper distribution of water or firefighting agent throughout the system, minimizing fire damage.

Factors to consider while buying a Threaded Equal Tees

Before purchasing this fitting, one needs to consider several factors:


The relevant material should be suitable for the specific application and compatible with other components.


The fitting size should match the pipes’ diameter to be connected.

Pressure Rating

The fitting’s pressure rating should match the system’s maximum operating pressure.


A threaded equal tee is an essential component for plumbing and irrigation systems. It ensures proper distribution and flow of water or wastewater and minimizes the chances of leakage. It is available in various types, materials, and sizes, making it suitable for various applications. These fittings are easy to install, durable, and versatile, making them popular among plumbers and irrigation professionals. Before buying a threaded equal tee fitting, one should consider several factors like material, size, and pressure rating to ensure system efficiency and safety.
