What is Teflon tape primarily used for?

Teflon tape, also known as plumber's tape or thread seal tape, is primarily utilized as a type of thread sealant to prevent leaks in piping systems. Its key function is to coat the threads of threaded connections, providing a tight seal that minimizes the chances of fluid or gas escaping through the joints. The tape's slippery nature allows for easy application and enables the threads to tighten effectively without compromising the integrity of the seal.

When wrapped around threaded pipes before joining them, Teflon tape fills the tiny gaps between the threads, creating a watertight seal that is resistant to many chemicals. This is crucial in plumbing and various industrial applications where leaks can lead to significant problems, such as water damage or the loss of pressurized gases.

Other options, while related to various aspects of piping and installations, do not accurately describe the primary purpose of Teflon tape. Enhancing aesthetics, insulating electrical components, and protecting against corrosion are different objectives that typically require other materials or methods.
