Advantages
The primary benefit of this brass reducer is its robust construction, which ensures long-term structural integrity even under varying pressure and temperature conditions. Its precise threading allows for easy installation and a tight seal, minimizing the risk of leaks in complex piping configurations. Furthermore, the brass material provides excellent thermal stability and resistance to environmental degradation, contributing to the overall longevity and efficiency of the plumbing system.
Suitable for
Connecting pipes of different diameters in heating systems

Industrial fluid transport networks
Adapting threaded connections in plumbing manifolds
This fitting may not be suitable for high-pressure steam applications or systems involving highly aggressive chemical substances that could compromise the integrity of the brass material. It is also not intended for use in environments where the pipe diameter requirements exceed the specified 1 1/4 inch or 3/4 inch thread dimensions.
Key specifications
Material: Brass
Connection type: Internal thread to internal thread
Size: 1 1/4 inch x 3/4 inch
Application: Plumbing and heating systems
To install the TDM Brass inner sleeve, ensure that the pipe ends are clean and free of debris. Apply an appropriate thread sealant, such as PTFE tape or a liquid pipe sealant, to the male threads of the connecting pipes. Carefully screw the reducer onto the pipes, tightening it with a suitable wrench until a secure fit is achieved. Avoid overtightening, as this may damage the threads or the fitting itself.
What to consider before purchase
Verify the thread sizes of your existing piping system
Ensure compatibility with the fluid type being transported
Check if additional sealing materials are required for your specific installation
For optimal performance, it is recommended to inspect the connection periodically for signs of moisture or leaks, especially after initial installation. Always ensure that the piping is properly supported to prevent excessive mechanical stress on the fitting.
