Constructed from high-quality brass, this component provides excellent resistance to corrosion and mechanical stress, ensuring long-term reliability in various fluid transport systems. Its design features internal threads on both ends, allowing for a seamless transition between pipes of different diameters while maintaining a tight, leak-proof seal.
Advantages
This brass inner sleeve offers exceptional durability due to the robust nature of the material, which withstands high pressure and temperature fluctuations common in modern heating and water supply systems. The precision-machined threads ensure easy installation and a high level of compatibility with standard piping components, reducing the risk of leaks and maintenance requirements. Its compact design allows for efficient use of space in tight installation areas, while the corrosion-resistant properties of the brass alloy guarantee a long service life even in demanding environments.

How to use
To install the TDM Brass inner sleeve, ensure that the pipe ends are clean, free of debris, and properly cut. Apply a suitable thread sealant, such as PTFE tape or a professional pipe joint compound, to the male threads of the connecting pipes. Carefully screw the pipes into the internal threads of the sleeve by hand, then tighten with an appropriate wrench until secure. Avoid overtightening to prevent damage to the threads or the fitting itself. Once installed, perform a pressure test to verify that the connection is completely leak-proof before putting the system into full operation.
What to consider before purchase
Verify that the pipe diameters match the 1 inch and 3/4 inch specifications
Ensure the thread type is compatible with your existing piping system
Check the operating pressure and temperature requirements of your installation
Confirm that the fluid being transported is compatible with brass fittings
Usage recommendations
Regularly inspect the connection points during routine maintenance of your plumbing system to ensure that no leaks have developed over time. If the system is exposed to extreme temperature changes, ensure that proper pipe support is in place to minimize mechanical stress on the fitting.
