Why is thread sealing tape used on pipe threads?

• A. To seal the joint and prevent leaks
• B. To lubricate threads
• C. To color-code pipes
• D. To protect threads from corrosion

Answer: (A)

Thread sealing tape is used on pipe threads to create a leak-tight joint by filling the small gaps between the threads. When the joint is tightened, the tape compresses and forms a seal that blocks liquids or gases from leaking out. It also helps the threads slide together more easily, but that easing effect is secondary to sealing. It isn’t meant for color-coding pipes or protecting threads from corrosion. If you’re applying it, wrap the tape in the direction of tightening so it doesn’t unravel as you assemble the joint.
