When it may not be suitable

How to use
To install the TDM Brass Union Tee, ensure that the pipe ends are clean and free of debris. Apply an appropriate thread sealant, such as PTFE tape or a compatible pipe sealant, to the male threads to ensure a watertight connection. Carefully thread the fitting onto the pipes by hand to prevent cross-threading, then use a suitable wrench to tighten the connection until secure. Avoid overtightening, as this can damage the threads or the fitting body.
What to consider before purchase
Verify the thread compatibility of your existing pipes
Ensure the 1/2 inch and 3/8 inch dimensions match your system requirements
Check local plumbing codes regarding the use of brass fittings
Confirm that the operating pressure and temperature of your system are within standard limits
Usage recommendations
Regularly inspect the connection points for any signs of moisture or corrosion after installation. If the system is subject to frequent thermal expansion and contraction, check the tightness of the fitting periodically to maintain a secure seal.
