To use 15mm-teflon-tape effectively without damaging the tape or the threaded parts, follow these steps:
Clean the Threads: Before applying PTFE tape, ensure that the threaded parts are clean and free from dirt, debris, or old thread sealant residues. Use a clean cloth or brush to remove any contaminants from the threads.
Choose the Right Tape: Select the appropriate width of PTFE tape for the threaded connection. In this case, use 19mm PTFE tape for 19mm pipe threads. Ensure that the tape is specifically designed for plumbing and pipe applications.
Start at the End: Begin wrapping the PTFE tape at the end of the male threaded part (the part that will be inserted into the female threaded part). Wrap the tape in the direction of the threads. For most threaded connections, clockwise wrapping is recommended.
