White Teflon tape, also known as PTFE tape, is a type of tape commonly used in plumbing and other applications to seal and prevent leaks in threaded connections. It is made from a thin film of polytetrafluoroethylene (PTFE), a synthetic fluoropolymer that is highly resistant to heat, chemicals, and moisture.
When wrapping white Teflon tape around a threaded connection, the tape acts as a lubricant, allowing the threads to be tightened more easily and creating a watertight seal. It is important to wrap the tape in a clockwise direction around the male end of the connection, so that it will not unravel when the female end is screwed onto it.
White Teflon tape is suitable for use with most types of plumbing materials, including metal, plastic, and rubber. It is also commonly used in other industries, such as automotive and aerospace, where high-performance seals and gaskets are required.
