What is Pipe Joint Tape?

Published in Plumbing Sealant 2 mins read

Pipe joint tape, also widely known as thread seal tape, PTFE tape, Teflon tape, or plumber's tape, is a specialized sealing material used primarily in plumbing applications.

Based on common usage and materials, pipe joint tape is:

  • A polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads.
  • Designed to fill the tiny gaps between pipe threads, creating a watertight and airtight seal.
  • Essential for preventing leaks in threaded pipe connections.

Material: PTFE Film

The core material of pipe joint tape is Polytetrafluoroethylene (PTFE), a synthetic fluoropolymer. PTFE is known for its excellent properties, including:

  • Non-stick surface
  • High chemical resistance
  • Temperature stability
  • Low friction

These properties make PTFE an ideal material for sealing threads, as it won't degrade easily and allows threads to be tightened smoothly without galling.

How Pipe Joint Tape Works

When pipe joint tape is wrapped around the threads of a pipe, it conforms to the shape of the threads. As the pipes are screwed together, the tape is compressed into the spaces between the male and female threads. This compressed PTFE creates a thin, impermeable barrier that effectively seals the joint, preventing water, gas, or other fluids from leaking out.

Common Names and Applications

As mentioned, pipe joint tape goes by several names:

  • Thread Seal Tape
  • PTFE Tape
  • Teflon Tape (Note: Teflon is a brand name for PTFE)
  • Plumber's Tape

Its primary application is sealing threaded connections in plumbing systems. It is used on:

  • Water pipes
  • Gas pipes
  • Air lines
  • Connections for fixtures like faucets, showerheads, and toilets

Different colors of tape are sometimes used to indicate compatibility with specific types of pipes or substances (e.g., yellow for gas lines, pink for potable water, white for general use).

Packaging and Form

The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads before connecting the pipes. The spool protects the tape and allows for simple application.
