How to use
To install the Jinan Meide brass coupling, ensure that the pipe ends are clean, deburred, and free of debris. Apply an appropriate thread sealant, such as PTFE tape or a liquid pipe sealant, to the male threads of the pipes being connected. Carefully thread the coupling onto the 3/4-inch pipe end and tighten it using a suitable wrench, ensuring not to overtighten to avoid damaging the threads. Repeat the process for the 1/2-inch connection. Once installed, pressurize the system slowly to check for any signs of leakage at the connection points.
What to consider before purchase
Verify the thread type and size requirements of your existing piping
Ensure the brass material is compatible with your specific fluid type
Check that the installation space allows for the use of a wrench
Confirm the pressure and temperature ratings of your system do not exceed the fitting's capacity
Usage recommendations
Always use professional-grade thread sealant to ensure a leak-proof connection and avoid using excessive force during installation to prevent thread stripping or cracking of the brass fitting.
