PTFE (Teflon®) Expansion Joints

PTFE Lined Expansion Joints

Multi-Purpose PTFE Lined Expansion Joints

Solid molded PTFE Lined expansion joints were developed to withstand higher pressures and temperatures in a space-saving design.  They are light-weight and corrosion resistant, available in Rubber and Metal.

PTFE is a synthetic fluoropolymer which finds numerous applications due to its non-stick nature, thermal stability, and high resistance to chemicals.  Elastomeric covering on solid PTFE and PTFE-lined metallic Expansion Joints are designed for environmentally corrosive applications.  A Kevlar® reinforcement overlay can be used to increase working pressures and provide additional safety factors for PTFE Expansion Joints.

Benefits of PTFE Lined Expansion Joints

  • Withstands higher pressures and temperatures
  • Ideal for installation where space limitations are a factor
  • Available in two, three and five convolution construction
  • Lightweight design
  • Corrosion Resistant
