What is the difference between standard and high-density PTFE tape for plumbing?

Standard PTFE tape is commonly used for general plumbing, household maintenance, and routine threaded water pipe connections.

High-density PTFE tape contains more PTFE material for a given tape size and generally provides greater thread coverage. It is often selected for professional plumbing, commercial installations, engineering projects, and applications where more consistent sealing performance is required.

The best choice should be based on the thread type, fitting size, operating conditions, and applicable project requirements.
