PTFE Tapes

PTFE (Polytetrafluoroethylene) tape is widely used in the plumbing industry due to their high resistance to both extreme temperatures and chemicals. PTFE is a staple of a plumber's toolbox.

Here at Cromwell, we offer a choice selection of PTFE tapes from our trusted, exclusive brand Kennedy as well as national brand 3M.

What are PTFE tapes?

PTFE (Polytetrafluoroethylene) tape, also known as plumber's tape or thread seal tape, is a non-stick, high-temperature resistant tape made of a thin film of PTFE material.

Why PTFE tapes?

PTFE tapes are used for their high temperature and chemical resistant properties. They also possess low friction properties and make leakproof connections.

When are PTFE tapes used?

It is commonly used in plumbing, HVAC, and industrial applications, for tasks such as sealing pipe threads and making leak-proof connections.

PTFE tape types

There are several types of electrical tapes available, each of which possess key attributes. To help you to find the best one for your needs, we've broken down each type to highlight the basic features of each.

Standard PTFE tape   -   Standard PTFE tape is the most widely used type. It has a thin film of PTFE material with a self-adhesive backing. Standard PTFE tape is suitable for general plumbing applications, such as sealing pipe threads, preventing leaks, and providing a smooth, lubricated surface for easy assembly and disassembly.

High density PTFE tape   -   High-density PTFE tape is denser and thicker than standard PTFE tape. It provides increased sealing effectiveness and is commonly used in high-pressure applications or with aggressive chemicals.

Gas PTFE tape   -   PTFE tape is specifically designed for gas line applications. It has a yellow color to indicate its use for gas connections and is typically thicker and denser than standard PTFE tape. Gas PTFE tape provides enhanced sealing properties to prevent gas leaks.

Considerations when choosing a PTFE tape

By considering the following factors, you can select the most suitable PTFE tape for your specific requirements, ensuring leakproof and reliable pipe connections as well as resistance to extreme temperatures and chemicals.

• Density and thickness - Evaluate the density and thickness of the tape. Thicker and denser tapes generally provide better sealing effectiveness, especially in high-pressure or aggressive chemical environments.

• Width and length - Select the appropriate width and length of the tape based on the pipe thread size and the coverage area required for effective sealing. Ensure that the tape is wide enough to cover the threads adequately.

• Temperature and chemical resistance - Consider the temperature range and the type of chemicals or substances the tape will come into contact with. PTFE tapes offer excellent resistance to high temperatures and a wide range of chemicals. Ensure the chosen tape is suitable for the specific temperature and chemical conditions.

• Compatibility with threads - PTFE tape is typically used for sealing pipe threads. Ensure that the tape is compatible with the materials used for the pipe threads, such as metal or plastic. Some tapes may have enhanced adhesion or compatibility with certain thread materials.

• Ease of application - Consider the ease of applying and wrapping the tape around the pipe threads. Some tapes have better conformability and ease of use, making them more convenient for application.

• Code and compliance - Check if the PTFE tape meets relevant industry standards, such as those set by plumbing codes or regulatory bodies, to ensure compliance and safety.


Is Teflon tape the same as PTFE tape?
Yes. Much like Velcro® and hook and loop tape, or Hoover and vacuum cleaner, Teflon™ is a brand name for PTFE tape. Other brands who manufacture PTFE tape will not be able to use the term Teflon™ tape when referring to the product.
