Fabric Expansion Joints

Fabric expansion joints provide stress relief for piping and ducting systems by absorbing thermal growth and shock, isolating mechanical vibration, and allowing for misalignments. 

These non-metallic, flue-duct expansion joints are available in eight standard profiles to fit your application requirements from -110°F up to 2,000°F. Fabric expansion joints are custom-designed with single-layer and composite belts and elastomers with excellent abrasion resistance.


  • Standard profiles include U-type, flat belt type, square, rectangular, and round
  • Excellent corrosion and chemical resistance
  • Baffles protect the inner surface from particulates in the gas stream
  • Retaining rings made from carbon or stainless steel


  • Stress relief for piping and ducting systems
  • Absorbs thermal growth and shock
  • Isolates mechanical vibration
  • Simple retrofit into existing ducting system
  • Cost-effective solution to compensate for movement in ducting systems
