How to use
To install the TDM Brass Union Tee, ensure that the pipe ends are clean and free of debris. Apply appropriate thread sealant, such as PTFE tape or liquid pipe sealant, to the external threads to guarantee a watertight seal. Carefully thread the fitting onto the pipes by hand initially to prevent 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 pipes to ensure compatibility with the 1-inch and 3/4-inch specifications.
Check the system pressure and temperature requirements to ensure they fall within the operational limits of brass fittings.
Ensure you have the necessary tools, such as pipe wrenches, for a secure installation.
Usage recommendations
Regularly inspect the connection for signs of moisture or leaks, especially after initial installation or system maintenance. Ensure that the piping is properly supported to prevent excessive mechanical stress on the fitting.
