PTFE/TEFLON EXPANSION JOINTS FOR PIPING
NOTE: Joints sizes 2-12″ I.D. are lined with PTFE.
Sizes 14″ and above are lined with FEP.
PTFE/Teflon Expansions Joint Features
Our PTFE expansion joints are made from the synthetic material Polytetrafluoroethylene. This non-reactive material is widely used in pipelines within the chemical manufacturing industry and acts as a protective agent against highly corrosive substances and withstands high temperatures.
