Types of PTFE Tape & Common Usage
White – Basic Thread Seal Tape
White is the standard colour for thread sealant tapes and it is recommended for basic plumbing jobs. Most households probably have a roll or two of white Teflon tapes, as it's an all rounder and good to use for less-critical, non-professional jobs. It is still sturdy with all the features of PTFE: high resistance to most chemicals, high resistance to extreme temperatures and can tightly seal threaded pipe connections.
Pink – Thread Seal Tape For Water Lines
Colour-coded for water lines, pink thread sealant tape is used by pipefitters and plumbers. As such, it is very heavy duty compared to the other standard type of tape.
Yellow – Thread Seal Tape For Gas Lines
Yellow thread seal tape meets all gas company standards for gas lines of all types, be it butane, propane, or natural gas. It's important to use the right thread seal tape for gas, and the yellow variety is the only safe choice.
Green – Thread Seal Tape For Oxygen Lines
Green thread seal tapes are required for oxygen applications, as it is grease-free yet does not allow fires to start.
Grey – Thread Seal Tape For Stainless Steel
Grey thread seal tape has a high-density rating and is nearly double the thickness of standard thread seal tapes, making it ideal for taping up stainless steel threads, preventing seizing and galling.
