Lining PTFE rubber joint on the basis of the general rubber joint, the interior lining with PTFE PTFE coating, coating is mainly white, can effectively protect the rubber joint from corrosive media erosion, such as strong acid and alkali or high temperature oil. The original mechanical and physical properties of the flexible rubber joint have not been affected a little, but can still compensate pipeline vibration, absorb pipeline displacement, reduce pipeline noise. Teflon coating can be effectively attached to the inner wall of the pipeline, to prevent the erosion of the medium or the pipeline tensile shrinkage produced by the detachment.

The PTFE rubber joint lining has the characteristics of vibration reduction, corrosion resistance, acid and alkali resistance, high temperature resistance, flexure and friction resistance. It is suitable for the connection of misalignment, displacement, size change and vibration part of pipeline. It can be used for the feeding and discharging pipe of storage tank, chemical industry, corrosion, vulcanization tank truck and other equipment, and can also be used for other special purposes. Polytetrafluoroethylene (PTFE, also called teflon, Teflon, Teflon, Teflon, 4F, and King of Plastics) is often called "non-stick coating" or "easy to clean material." The lining material tetrafluoride has excellent chemical stability and corrosion resistance. In addition, it has sealing, high lubricity, non-viscosity, electrical insulation, good aging resistance, excellent temperature resistance (can work for a long time at +250℃ to -180℃).
