Today, it’s hard to imagine a plumber not using Teflon tape. The tapes are used to seal various types of threads in plumbing, heating and sewage systems of homes. Teflon does not break or deteriorate, unlike its counterparts on the market. When it appeared on the market, it quickly replaced the special adhesives used until then. The product is made of a white polymer containing fluorine, often called Teflon. It is also commonly used in everyday life (e.g. Teflon coated pots). Teflon tape is available in different densities, thicknesses and widths.

Teflon is a versatile material and can be used for a variety of purposes. As already mentioned, it is used to seal various types of cylindrical threaded joints. It is used by plumbers, gas workers and fitters. But pipe sealing is not the only area of application. Teflon tape can insulate electrical components from each other. Teflon does not change its properties at very high or low temperatures, and retains its flexibility and stability. It does not react with water, making it ideal for plumbing systems.

How to use Teflon tape?

how to use teflon tape clockwise movements around the thread

To begin with, it is extremely important to clean the thread from rust, scale and any dirt. Then, degrease it.
Remember to always apply the tape clockwise to the direction that is facing you. Otherwise, your tape will bunch up, and it’s not going to be able to seal. Start at the top of the thread, holding the tape with your finger to prevent it from peeling, and work your way down. Finish winding when the thread is completely hidden. Press the tape with your hand – as if you had wrapped your palm around the thread. This ensures that the tape fills the threads accurately. If this is not done, there is a risk of high pressure water making its way out. Finally, screw the part by hand. Take a wrench and press the connection down.
