Teflon tape or thread sealant is a simple yet effective material found in tradie toolkits worldwide. Also known generically as PTFE tape, it's generally used as a sealant and lubricating material, perfect for installing fittings in the kitchen and bathroom.

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. 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.
