Constructed from high-quality nickel-plated brass, it provides excellent structural integrity and long-term resistance to corrosion, making it a dependable choice for professional water supply installations.
Advantages
This union tee offers exceptional durability due to its robust nickel-plated brass construction, which effectively prevents oxidation and ensures a long service life even in demanding environments.

Its versatile design simplifies the branching of piping networks, providing a stable and permanent connection that meets professional plumbing standards.

When it may not be suitable

It should also be avoided in systems where the piping material is incompatible with brass to prevent galvanic corrosion.

How to use
To install the TDM Brass union tee, ensure that the pipe ends are clean, deburred, and free of debris. Apply an appropriate thread sealant, such as PTFE tape or liquid pipe sealant, to the male threads of the connecting pipes. Carefully thread the pipes into the fitting by hand to avoid cross-threading, then tighten securely using a suitable wrench. Do not overtighten, as this may damage the threads or the fitting body.
What to consider before purchase
Verify the thread sizes of your existing piping to ensure compatibility with the 3/4" and 1/2" female connections.
Check the pressure and temperature ratings of your system against the specifications of the fitting.
Ensure you have the necessary tools and sealing materials for a professional-grade installation.
Usage recommendations
Regularly inspect the connection points for any signs of moisture or leaks after the initial installation and during routine system maintenance to ensure continued operational safety.
