Teflon tape has primarily one use, which is in plumbing. This durable tape is meant to be durable and waterproof at the same time.
What Is It?
Polytetrafluoroethylene tape is the proper name of this material. It is typically white in color and is not a tape at all. The reason it is called a tape is because of the way it is rolled onto a spool.
This product is used in many plumbing applications to provide a seal between two pipes. This material when used with threaded pipes forms a seal between the two pipes. It is a thin material that sticks to itself and is vinyl like.
How It Works?
When attaching two threaded pipes the Teflon tape is wrapped around the male pile and it makes attaching the two pipes together easier. The plumber or repair person, will wrap it around the pipe by overlapping the tape and winding it around the entire threaded end of the pipe.
When the female end is screwed on a tight seal is formed between the two pipes. This helps to prevent leaks.
Where to Purchase
Teflon tape can be found in hardware stores and home improvement stores. It costs usually less than a dollar and can come in color coded models. It can be found in any place that plumbing supply is sold.
Blue or Orange tape is usually thicker and used for gas pipe connections and can be purchased from the same the sources that sell the Teflon variety.
This type of tape is rather thin and is always put on by hand, care must be taken when using this product that a piece does not break off and fall into the pipe especially when using this tape to seal gas pipes.
If a piece breaks off and falls into the line it could block the line and stuff it up, or in the case of gas pipes it can stop up the valve. Care should be taken when using this product to insure a clean seal with clean lines.
It is a good rule of thumb to keep some Teflon tape around the house just in case for emergency repairs until a plumber can be called or until the pipe can be replaced.
Teflon tape is a wonder that is a cheap efficient way of making sure those pipes are sealed and to prevent leaks down the road.
