Teflon tape will not fix stripped threads on a pipe or fitting, as it is strictly designed to act as a thread sealant and lubricant for minor gaps rather than restoring structural integrity. When threads are stripped, the metal or plastic ridges that hold the male and female connectors securely together have been worn down, sheared, or flattened, meaning the components cannot achieve proper mechanical engagement or tension. Wrapping Teflon tape around stripped threads may provide a brief, temporary illusion of grip, but internal water or gas pressure will quickly blow past the seal and cause the joint to fail. The only permanent and safe solution for stripped threads is to completely replace the damaged pipe fitting or connector.
