## Long description

The TDM Brass union tee is a precision-engineered plumbing fitting designed to facilitate secure and leak-resistant connections within water supply and heating infrastructure. Constructed from high-quality brass, this component provides excellent durability and resistance to corrosion, making it a reliable choice for both residential and commercial piping systems. The fitting features a specific transition design, allowing for a seamless connection between pipes of different diameters while maintaining structural integrity under operational pressure.
Advantages
This brass union tee offers superior mechanical strength and longevity compared to plastic or lower-grade metal alternatives. Its robust construction ensures that it can withstand the thermal expansion and contraction common in heating systems without compromising the seal. The precision-cut threads allow for smooth installation and reliable tightening, reducing the risk of cross-threading or mechanical failure during assembly. Furthermore, the use of high-grade brass ensures compatibility with various water types, minimizing the risk of degradation over time.
Suitable for
Connecting pipes in domestic water supply systems
Integrating components in central heating installations
Transitioning between 1 1/2 inch and 1 1/4 inch pipe diameters
Professional plumbing repairs and new system assemblies
When it may not be suitable
This fitting is not intended for use in high-pressure industrial steam systems or environments involving highly corrosive chemical substances that may react with brass. It should also not be used in applications where the pipe material is incompatible with brass, as this could lead to galvanic corrosion.
Key specifications
Material: Brass
Connection 1: 1 1/2 inch external thread
Connection 2: 1 1/4 inch internal thread
Configuration: Union tee
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 a compatible pipe joint compound, to the male threads to ensure a watertight seal. Thread the fitting onto the pipes by hand initially to ensure proper alignment, then use a suitable wrench to tighten the connection securely. Avoid overtightening, as this may damage the threads or the fitting body.
What to consider before purchase
Verify the thread type and size requirements of your existing piping system
Ensure the installation space allows for the use of a wrench
Check for compatibility with the pipe material to prevent galvanic corrosion
Usage recommendations
Regularly inspect the connection for signs of moisture or leaks after the initial installation and during routine maintenance of the plumbing system. Ensure that the system pressure remains within the rated limits for brass fittings to maintain long-term performance.
