Introduction

Types of PTFE Tape

1. White PTFE Tape (Standard)
   Recommended for most residential and light commercial plumbing connections. White PTFE tape provides a thin and flexible seal that offers tight sealing for bathrooms, kitchens, and general plumbing fixtures. This type of tape is a favorite among home users. Consider Maodali's white PTFE tape.
   

2. Yellow PTFE Tape (Gas Pipe)
   Yellow PTFE tape is thicker and designed specifically for gas applications, suitable for propane, butane, and natural gas connections. Its thickness and durability provide a safer seal, ensuring no leaks in high-risk environments. Be sure to choose a standard-compliant product, such as Maodali's yellow PTFE tape for gas.
   

3. Pink PTFE Tape (Heavy-Duty Water Pipe)
   Pink PTFE tape is designed for high-pressure and industrial-grade water systems. Its increased thickness is suitable for commercial-grade water systems and connections that need to withstand significant water pressure. Choosing the right brand, like Maodali's 12MM pink PTFE tape, ensures long-lasting sealing effects.
   

4. Blue PTFE Tape (Specific Applications)
   Blue PTFE tape is commonly used in plumbing and air conditioning systems, suitable for high-pressure water pipe connections, providing excellent sealing performance. Consider Maodali's blue PTFE tape.
   

How to Use PTFE Tape Correctly

1. Clean the Threads

   • Tip: Use a cleaning cloth or brush to remove dust, grease, and rust from the threads, ensuring they are clean.
   • Note: If there is old PTFE tape residue on the threads, be sure to remove it completely to ensure effective adhesion of the new tape.

2. Wrap the Tape Correctly

   • Steps:
     • Start wrapping the PTFE tape from the base of the threads in a clockwise direction.
     • Wrap 3-5 turns, ensuring there are no gaps between each turn.
   • Tip: While wrapping, gently pull the tape to ensure it adheres evenly and flatly to the threads, avoiding wrinkles.
   • Note: If the tape is too tight, it may damage the threads; if too loose, the sealing effect will be reduced.

3. Tighten the Joint

   • Steps:
     • Gently place the nut or joint back, ensuring it aligns with the threads.
     • Use a wrench to tighten the joint clockwise until you feel moderate resistance.
   • Tip: Use a manual wrench instead of a power tool to avoid applying too much force.
   • Note: After tightening, check the connection again to ensure there are no leaks.

Common Mistakes and How to Avoid Them

• Incorrect Wrapping Direction: Ensure the tape is wrapped in a clockwise direction to prevent it from loosening when tightening the joint.
• Using Excess Tape: Overuse of tape can lead to poor sealing; using an appropriate amount achieves the best effect.
• Choosing the Wrong Type: Using the incorrect type of tape in gas or oxygen systems can pose safety risks; ensure you select the appropriate PTFE tape based on application needs.

Case Studies

1. Application in Residential Gas Piping
   A homeowner used yellow PTFE tape to seal connections when installing a new natural gas stove. By following the correct wrapping method, a safe and leak-free connection was ensured, avoiding potential fire risks.

2. High-Pressure Water Piping in Commercial Buildings
   In a newly constructed commercial building, plumbers used pink PTFE tape to connect high-pressure water pipes. After several months of use following project completion, no leaks occurred, indicating that the choice of pink PTFE tape was very successful.

3. Use of Blue PTFE Tape in Air Conditioning Systems
   An air conditioning company used blue PTFE tape to seal water pipe joints while installing a new cooling system. After maintenance, technicians found the system operating well with no leaks, confirming the effectiveness of blue PTFE tape.
