Advantages
This brass union tee offers superior durability and structural integrity compared to plastic or lower-grade metal alternatives.

Suitable for
Residential water supply systems

Key specifications
Material: Brass
Configuration: 1" x 3/4" x 1"
Connection types: Combination of internal and external threads
Primary thread: 1" Male thread
Secondary thread: 3/4" Internal thread
To install the union tee, ensure the pipe ends are clean and free of debris. Apply appropriate thread sealant, such as PTFE tape or liquid pipe sealant, to the male threads to ensure a watertight connection. Thread the component onto the pipes by hand until firm, then use a suitable wrench to tighten it to the required torque, taking care not to overtighten and damage the threads.
What to consider before purchase
Verify the thread sizes of your existing piping to ensure compatibility with the 1" and 3/4" dimensions.
Check the system pressure and temperature ratings to ensure they fall within the operational limits of brass fittings.
Ensure you have the necessary tools, such as pipe wrenches, for proper installation.
Usage recommendations
Regularly inspect the connection for signs of moisture or corrosion during routine system maintenance to ensure long-term integrity.
