Maintains Seal under Pressure and after Slight Adjustments

An Indian manufacturer of domestic water purifiers used ptfe tapes to seal the plastic pipe thread joints. Though no leaks were detected at assembly / testing stage, the joints loosened during transportation & handling causing leak. PTFE tapes offeres lubricity that many times results in over tightening of the plastic joints – leasing to cracks and under vibrations – aids loosening. PTFE tapes also tend to shred and lose their sealing properties when the joints are re-adjusted.
