Since the PTFE is malleable, deformable and impermeable, it acts a little like putty under compression, being forced into small gaps between threads in order to create an air- and watertight seal when threaded into a joint.

The tape is commonly used commercially in pressurized water systems, such as central heating systems, as well as in air compression equipment and thread joints with coarse threads.

Details:

• PTFE Thread Sealing Tape
• Seals your fittings (if needed) to prevent serious water leaks
  
  

Note: We recommend using this thread tape for fittings which do not have an O-ring seal.

Tips:

• Start wrapping the male threads at end of the pipe but do not lap over the end. Doing so may result in reduced water pressure or even clogs from bits of the tape that get into the water supply.
• Start with a couple loops around at the end, then wrap all the threads, overlapping half the width of the tape on each wind.
• Wrap in the direction of the threads starting from the end and proceeding toward the length of the pipe. Wrapping the wrong way may result in the tape coming unwound as the fittings are tightened.
• As you wrap, keep tension on the tape so that it is pulled into the threads.
• If you loosen or disconnect a fitting, remove the old tape and rewrap with a fresh piece.
