What is PTFE Tape?

PTFE Tape is a sealing material made from PTFE, commonly known as “Thread Seal Tape.”

Properties:

 

• Resistant to Chemicals: It doesn’t react with most chemicals. It works well with acids, bases, and solvents.
• Handles Extreme Temperatures:Works in a wide range from -200°C to 260°C (-328°F to 500°F).
• Great Sealing Ability: Stretches well and seals tightly.
• Good Insulation & Durability : Doesn’t conduct electricity and doesn’t break down easily over time.

 

Types of PTFE Tape:

Standard Thread Seal Tape

Expanded PTFE Tape

PTFE Film Tape

PTFE Fiberglass Tape

Anti-Static PTFE Tape

 

What is it used for?

 

Gas Pipes:Seals threaded connections to prevent gas leaks and ensure safety.

Fuel & Oil Lines:Used in small fuel systems and oil/lubrication pipelines to seal threaded joints.

Ear Stretching (Body Modification):Because it’s non-allergenic, heat-resistant, and stretchy, it helps slowly stretch ear piercings with less risk of tearing or infection.

 

How to Use It:

Step 1:Clean the tape and pipe threads to remove oil or water.

Step 2:Check the thread’s twist direction. Start wrapping from the end of the thread.

Step 3:Wrap tightly to the end. Press it down gently to hold it in place, then cut off the extra tape.

How Does PTFE Tape Work?

PTFE Tape is soft and flexible. When the threads are tightened, the tape squishes and fills the tiny gaps between threads. This blocks leaks and creates a seal. The tape is also smooth, heat-resistant, and doesn’t react with chemicals.

 

PTFE Tape vs Teflon Tape

There’s no real difference—they’re the same material: PTFE.

 

 “PTFE Tape” focuses on the material name.

“Teflon Tape” uses the brand name “Teflon,” which was created by DuPont and is now owned by Chemours.

 

FAQ:

 

Colours:

The standard colour is white (natural PTFE).

Black:More heat and corrosion resistant

Gray:Neutral tone

Blue:Strong chemical resistance

Green:Often used for eco-friendly products

Custom colours are available if needed.

 

Wrapping Direction:

Always wrap the tape in the same direction as the threads twist. This way, the tape won’t loosen when you screw the parts together—it will stay tight and sealed.
