What is Teflon Tape?
Teflon tape is a versatile film strip mostly used by plumbers, commonly as a joint sealer to seal the pipe's threads and sometimes as a leakage preventer. It is also known as Thread seal, plumber's strip, or polytetrafluoroethylene film, abbreviated as PTFE tape. It is quite a necessary item in most cases involving plumbing requirements. Since it is very convenient and easy to use, it can be found in most plumbers' toolboxes. It is not generally used in cases of plastic fittings where it is likely to cause problems. It also acts as a lubricator in most piping connections threaded in which there is no in-built seal. It is available wounded on a spool and makes it easier to wrap around the threads of piping joints; it is cut to specific thickness or widths.

While using the strip, it is applied or wrapped around the joint two to three times and then pulled tight to secure appropriately and thus make it watertight, after which the nut is screwed. Teflon taps also works as a better option than an electrical strip that is thicker and does not help much where gas pressure must be sealed. The plumber's strap is sufficiently thick and dense because PTFE has very low surface friction.
It is also vital to understand the different temperature ratings provided by various brands and formulations. If one is not sure what the temperature demands are for a specific use or environment, it is suggested to procure expert assistants. The minimum temperature that is safe for operating PTFE strips is around -200 degrees Celsius, and the maximum heat is around +260 degrees Celsius. As these are non-sticky, it is easy to remove them or reapply later as the case may be.
Use of Teflon Tape:
The uses of the Thread seal are figured or precisely analyzed according to the task undertaken. Plumbers typically use these strips to install fittings in a kitchen or a bathroom and outdoors, such as water taps in the garden, etc.
Commercially, these are used in radiators, water pressure systems or hydraulic applications, air compressors, and centrally heating equipment and the likes. These thread seal strips are also used in ducting application works. It is generally used in the threaded piping connections or joints that are usually supposed to have an in-built rubber seal or a gasket to secure it more effectively during the installation works or plumbing projects.
These Thread seal straps could also act as deformable fillers and fill any gaps between the threads or connections. The physical composition and the chemical inertness of the Thread seal make it oil and petrol resistant, and therefore it can also be used in the automotive area application. One must be careful with using these strips as it can be dangerous when not appropriately applied or overused.
There are various types of these that vary according to the requirement. The most commonly used ones are white in colors that are mostly used in plumbing projects or applications. Another available variety is yellow, used in gas pipelines and fuel lines, pink used in potable water, and green for medical purposes, specifically oxygen lines, etc.
Where to Buy Teflon Tape?
Some many industries and manufacturers deal in the supply and exportations of these straps in India and internationally. Thread seal strips are also available and can be bought online from many e-commerce websites such as Amazon, Flipkart, Shopclues, Snapdeal, Walmart, etc.
Teflon Tape Sizes:
The Thread seal strip's size mostly depends on the threads' size where it is intended to be used, and the product and the price vary accordingly. White ones are single density and mostly used in plumbing threads up to 3/8 inch are generally ½ inch wide.
Yellow ones are doubly dense and hence used in gas fittings require thicker straps. ¾ inch wide strap is sufficient for 2-inch threads.Green ones are triple density and therefore used on medical gases require oil-free PTFE tapes. The grade and standards are relevant in terms of the industries where it is used. Europe and the US have specified grades of PTFE.
Best Teflon Tapes:
There are enormous types and brands of Thread seal straps available nowadays, and case specifications determine the quality and standard. With all the surge of professional products as well as DIY work necessities, different brands provide particular strengths and offer qualities specific to areas of application.
So they are to be chosen wisely as per the use and the application area. It is also to be noted that if any point in time the pipe connections are to be dismantled or unscrewed, the PTFE ones also help prevent them from sticking or seizing up. There is a casual difference between plumber's strip and Teflon, as in some situations, the former may be referred to as the latter, which is not correct in a technical way.
Teflon is identical to PTFE in terms of its functionality or chemical composition. Still, a particular brand has ceased to manufacture in the form of tapes by the existing trademark holder, Chemours.
Any reference to Teflon strips mostly applies or refers to Thread seal tape or PTFE or Plumber's tape nowadays. Thread seal strips or plumber's tape are also beneficial and advantageous to professional workers and a DIY plumber as it tends to remain fresh in the toolbox even after years and is also very easy and convenient to use. Another significant factor about these strips is that they are very inexpensive and affordable and readily available in the market.
