When it may not be suitable

Key specifications

Connection type: Male-Female threaded
Diameter: 3/4 inch
Length: 20 mm
How to use
To install the TDM Brass Extender, ensure the pipe ends are clean and free of debris. Apply an appropriate thread sealant, such as PTFE tape or liquid sealant, to the male threads to ensure a watertight connection. Thread the extender onto the existing pipe or fitting by hand, then tighten it securely using a suitable wrench. Avoid over-tightening to prevent damage to the threads or the fitting itself. Once installed, pressurize the system slowly to check for any signs of leakage.
What to consider before purchase
Verify that the 3/4 inch thread size matches your existing piping
Ensure the 20 mm length is sufficient for your specific extension requirements
Check compatibility with the pipe material to prevent galvanic corrosion
Confirm that the operating pressure and temperature are within the limits of brass fittings
Usage recommendations
Regularly inspect the connection for signs of moisture or corrosion during routine system maintenance. If the fitting is removed for repairs, it is recommended to replace the thread sealant before reinstallation to maintain a reliable seal.
