The thickness of Teflon tape, also known as PTFE (polytetrafluoroethylene) tape, can vary between different brands and products. Generally, Teflon tape comes in thicknesses ranging from 0.003 to 0.005 inches (0.076 to 0.127 mm). The most common thickness for standard plumbing applications is around 0.004 inches (0.1 mm).

Teflon tape is thin and flexible, making it easy to wrap around the threads of pipes and fittings. The tape is designed to fill gaps between the threads and create a seal that helps prevent leaks. While it may seem delicate due to its thinness, Teflon tape is effective in providing a reliable seal when applied correctly.

When using Teflon tape, it’s important not to use excessive amounts. A few wraps around the threads are usually sufficient to create an effective seal. Overusing the tape can lead to difficulties when tightening the fittings and may not improve the sealing properties.

Always follow the manufacturer’s recommendations and guidelines regarding the application of Teflon tape and pay attention to the specific requirements of your plumbing or pipe sealing project.
