There are many small items in home renovation that, though unnoticeable, play an indispensable role throughout the entire process. One of these is PTFE tape, which many people are not familiar with. However, it is widely used in plumbing and electrical projects in home renovations. Today, we will detail the characteristics, uses, and correct application methods of PTFE tape to help you master its use in simple plumbing tasks.

1. Characteristics and Functions of PTFE Tape

PTFE tape, also known as "Polytetrafluoroethylene tape," is an essential material used in liquid pipeline installation. Its main component is PTFE, which has excellent chemical stability, and can withstand high and low temperatures, resist corrosion, and aging. Additionally, PTFE tape offers excellent sealing properties, lubrication, non-stick characteristics, and non-toxicity, making it widely used in industries such as machinery, chemicals, and electricity.

In home renovation plumbing projects, the primary function of PTFE tape is to enhance the sealing of pipe connections, preventing leaks in water and gas systems. For example, when replacing a faucet or installing a gas valve, PTFE tape ensures that the connection is sealed properly, preventing leaks caused by friction, pressure, and other factors.

2. Application of PTFE Tape in Home Renovation Plumbing Projects

In home renovation, PTFE tape is primarily used in plumbing projects, especially in the following scenarios:

1. Gas System:

   • Connection of gas pipes to gas valves
   • Connection of gas meters to pipes
   • Connection of the gas main pipe to the house

2. Water Pipe System:

   • Iron plug installation: Used to seal the water pipe's inner thread when fixtures are not yet installed.
   • Angle valve installation: Used for sealing pipe branch joints.
   • Washing machine and mop sink faucet installation
   • Shower mixing valve installation

By using PTFE tape, plumbers can ensure that these connections do not leak water or gas, improving the overall safety and longevity of home renovations.

3. Correct Use and Precautions for PTFE Tape

Proper technique is crucial when using PTFE tape. Following the correct steps ensures that the seal of the connection is not compromised. Here are the steps for using PTFE tape and some important precautions:

1. Usage Steps

Taking the connection of a gas valve as an example, the winding method for PTFE tape is as follows:

• Step 1: Hold the gas valve with your left hand, facing the threaded end (where the tape will be applied). Unroll the PTFE tape and start winding it around the threads in a clockwise direction, ensuring the tape is centered.

• Step 2: Generally, wind the tape around 15 times. If the tape is thin, add 3-5 more wraps. After wrapping, cut off any excess tape, making sure the cut end is flush with the wrapped surface.

• Step 3: Hold the gas valve with the PTFE tape wrapped around it and align it with the corresponding threaded component. Slowly screw it in clockwise. Be careful not to apply too much force to avoid damaging the parts.

• Step 4: Once you cannot screw it in any further, use an adjustable wrench to tighten it, ensuring a good seal.

• Step 5: After installation, open the gas valve and apply soap or dishwashing liquid to the connection. Check for any bubbles. If it's a water fixture, turn on the water valve and observe for any leaks.

• Step 6: Avoid turning the PTFE tape counterclockwise during installation, as this could compromise the seal and lead to gas or water leakage.

2. Precautions

• Reverse rotation risk: Do not rotate the PTFE tape counterclockwise during installation, as this can affect the sealing effect and cause leaks.
• Number of wraps: If the tape is thin, you may need to increase the number of wraps to ensure a tighter seal.
• Hidden installation points: For concealed installations, like angle valves inside kitchen cabinets, consider omitting the decorative cover plate for easier access.
• Rubber gasket usage: In some connections where a rubber gasket is used, PTFE tape can act as a supplementary sealing material to enhance the seal, especially in connections between metal hoses and angle valves.
