What is the best PTFE tape for water pipes?

For most water pipe connections, choose a PTFE thread seal tape designed for plumbing and water systems. The right tape depends on the pipe material, thread size, installation conditions, and applicable drinking-water requirements.

Standard PTFE tape is suitable for general plumbing and maintenance, while higher-density PTFE tape provides greater material coverage and is often preferred for professional plumbing, commercial installations, and demanding water systems.

For potable water applications, choose PTFE tape with appropriate drinking-water approvals, such as WRAS or ACS, where required by local regulations or project specifications.
