Yellow PTFE tape is a polytetrafluoroethylene (PTFE) film for use in sealing pipe threads to eliminate movement and leakage in a threaded joint. This tape works as a deformable filler, helping to seal the joint without hardening or making it more difficult to tighten.
- Helps prevent Bi-Metal corrosion in thread joints
- Reduces chance of threads seizing when unscrewed
- Deformable filler
