Espa?olTo use 19mm PTFE thread tape (PTFE 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.
Overlap the Wraps: Apply the PTFE tape with a slight tension to ensure a snug fit but avoid stretching the tape excessively. Overlap each wrap by about 50%, covering the threads completely. Usually, 3 to 5 wraps are sufficient for a standard threaded connection.
Avoid Excessive Wrapping: Avoid using too many wraps of PTFE tape, as excessive wrapping can lead to over-tightening, tape deformation, and difficulty in disassembly.
No Tape on the First Thread: Leave the first thread exposed, without any PTFE tape. This helps to prevent tape particles from entering the flow and ensures a clean connection.
Smooth Down the Edges: After applying the tape, smooth down the edges of the tape to ensure that there are no loose ends or rough edges that can interfere with the proper sealing.
Insert and Tighten: Insert the male threaded part into the female threaded part and tighten until snug. Use an appropriate wrench or tool to achieve the recommended torque, but avoid over-tightening.
Check for Leaks: After tightening, check the connection for any signs of leaks. If you notice any leaks, slightly tighten the connection without over-tightening.
Use Only on Tapered Threads: PTFE tape is suitable for tapered pipe threads (NPT or BSP threads). Do not use PTFE tape on parallel threads, as it may not create an effective seal.
