22. Teflon Tape: The Plumber’s Friend
PTFE, better known as Teflon tape, is a staple in every plumber’s toolkit. Wrapped around pipe threads, this thin, white tape creates a watertight seal that prevents leaks in plumbing and gas lines. Its slippery nature makes assembly easier and helps ensure long-lasting, drip-free connections. No wonder it’s a go-to solution for professionals and DIYers alike. (Source: Family Handyman)
