Tees

Malleable Iron Equal Tees are three-way pipe fittings used to connect three sections of pipe at 90-degree angles, allowing flow to be split or combined within a system. Manufactured from malleable iron with BSP threaded female connections, they provide a strong and reliable solution for a wide range of mechanical, fire protection and industrial applications.

 
They are a core component in threaded pipework systems and are widely used in building services and industrial installations.

Key Features

• Three-way equal tee configuration 
• Female BSPT threaded connections 
• Manufactured from durable malleable iron 
• High strength for pressure-bearing systems 
• Suitable for water, gas, oil and fire protection use 
• Compatible with standard steel pipe systems 
• Available in black and galvanised finishes

Product Description

Equal tees are designed to allow a pipeline to branch at 90 degrees while maintaining the same pipe size across all three outlets. This makes them one of the most commonly used fittings in threaded pipework systems, providing a simple and efficient method of distributing or combining flow.

 
Manufactured from malleable cast iron, these fittings offer a strong yet slightly ductile structure, allowing them to withstand installation torque, vibration and pressure fluctuations without cracking. This makes them well suited to demanding service environments.

 
Each tee typically features BSPT (British Standard Pipe Taper) female threads, designed to create a secure, leak-resistant joint when installed with appropriate sealing compounds or PTFE tape. The tapered thread profile ensures reliable engagement and long-term sealing performance across a wide range of operating conditions.

 
Manufactured to recognised standards such as BS EN 10242, malleable iron tees are designed for consistent quality and compatibility with standard steel pipe systems. They are commonly rated for pressures up to 25 bar and suitable for operating temperatures from sub-zero conditions up to elevated service temperatures in industrial applications, depending on specification.

 
These fittings are widely used in fire sprinkler systems, plumbing installations, HVAC networks and general industrial pipework. Their versatility makes them a fundamental component in both simple and complex piping layouts.

 
Available in Black (self-colour) for general internal use or systems that will be painted or coated, and Hot Dip Galvanised (HDG) for enhanced corrosion resistance in external or more aggressive environments.

Applications

Ideal for fire sprinkler systems, plumbing, heating, gas and oil pipework, HVAC installations and industrial services where a three-way branch connection is required within threaded pipework systems.
