Buying Guide: Choosing PTFE Thread Seal Tape

White Tape for General Plumbing
The white Black Swan tape is a PTFE thread seal tape for general plumbing. One white option is a low-density tape with a flexible design that wraps smoothly around threads and helps prevent leaks in plumbing connections.

The yellow Black Swan tape is a high density PTFE tape intended for natural gas, propane, butane, water, oil and chemical lines. It comes as a 0.5 in by 260 in roll. For gas lines, have a qualified technician do the work and follow the manufacturer's instructions.

Pipe Materials for 1/2 in and 0.75 in White Tape
The 1/2 in and 0.75 in white tapes are used on iron, brass, aluminum, ceramic, plastic, synthetic rubber, monel and carbon pipe. Check the pipe material before you choose a roll.
