## Long description

The TDM Brass threaded union connection is a professional-grade plumbing fitting engineered for creating secure and reliable joints in piping systems. With a 3/4 inch connection size, this component is specifically designed to facilitate easy assembly and disassembly of pipes without the need to rotate the entire pipeline. Crafted from high-quality brass, it offers exceptional durability and long-term performance in both residential and commercial water supply and heating applications.
Advantages
This union connection stands out due to its robust brass construction, which provides superior resistance to corrosion, rust, and mechanical wear. The precision-machined threads ensure a tight, leak-proof seal, minimizing the risk of water damage or pressure loss. Its design allows for convenient maintenance, as the union can be disconnected quickly when repairs or system modifications are required, saving significant time and effort during plumbing work.
Suitable for
Connecting water supply pipes in residential buildings
Integrating components into heating systems
Maintenance and repair of existing plumbing lines
Industrial fluid transport systems where frequent disconnection is necessary
When it may not be suitable
This fitting is not intended for use with aggressive chemicals or high-pressure steam systems that exceed the material's thermal and pressure ratings. It is also not suitable for pipes made of materials that are incompatible with brass, as this could lead to galvanic corrosion.
Key specifications
Connection size: 3/4 inch
Material: High-quality brass
Type: Threaded union connection
Application: Water supply and heating systems
How to use
To install the TDM Brass union, ensure that the pipe ends are clean and free of debris. Apply a suitable thread sealant or PTFE tape to the male threads to enhance the seal. Screw the two halves of the union onto the respective pipe ends using appropriate wrenches. Once the pipes are aligned, tighten the central nut of the union to compress the internal seal, ensuring a secure and leak-free connection. Always check for leaks under pressure after installation.
What to consider before purchase
Verify the pipe diameter matches the 3/4 inch specification
Ensure compatibility with the existing piping material to prevent corrosion
Check the pressure and temperature requirements of your specific system
Confirm that there is sufficient space for the union fitting in the installation area
Usage recommendations
Regularly inspect the connection for signs of moisture or corrosion, especially in heating systems. If the union is disconnected for maintenance, it is recommended to replace the internal seal or reapply thread sealant before reassembly to maintain optimal performance.
